A component package enabling the transformation of a 1973 to 1987 General Motors two-wheel-drive pickup truck or SUV into a four-wheel-drive vehicle is a collection of parts designed for this specific purpose. This includes items such as a transfer case, front axle assembly, modified driveshafts, suspension components, and associated hardware required for the conversion. An example would be a kit containing a Dana 44 front axle, an NP205 transfer case, and lift springs, along with the necessary brackets and bolts.
The appeal of such a modification lies in the enhanced off-road capability, increased traction in adverse weather conditions, and potential improvement in vehicle resale value. Historically, these conversions were popular due to the relative simplicity of the older vehicle platforms and the desire to add four-wheel drive to vehicles not originally equipped. This modification offered a cost-effective alternative to purchasing a new four-wheel-drive vehicle.
The subsequent sections will detail the necessary components, installation considerations, potential challenges, and relevant aftermarket options for undertaking such a project.
1. Transfer Case Selection
The heart of any ’73-’87 GM 2WD to 4WD conversion lies in the transfer case. This component, often overlooked in its complexity, dictates how power is distributed to the newly installed front axle. The selection isn’t merely about bolting in a readily available unit; it’s about orchestrating a symphony of mechanical interactions. The wrong choice can lead to mismatched gear ratios, driveline vibrations, and ultimately, a catastrophic failure. A prevalent example is the improper pairing of a New Process 203, known for its full-time four-wheel drive, with axles geared for part-time use. The result? Binding, excessive wear, and potential breakage on paved surfaces. Therefore, the transfer case selection directly impacts the usability and longevity of the entire conversion.
Consider a scenario: A restorer, aiming to recreate a factory-appearing K10, might opt for a New Process 205 gear-driven transfer case, known for its robustness and straightforward operation. However, this choice necessitates modifying the transmission output shaft and adapting the floor pan for shifter clearance. Conversely, selecting a chain-driven transfer case, such as an NP208 or NP241, offers smoother operation and potentially easier installation, but might sacrifice some of the durability prized by off-road enthusiasts. The decision pivots on intended use and the willingness to address the accompanying modifications. The practical consequence is that time invested in researching compatible gear ratios, spline counts, and shifter linkages directly translates into a more reliable and enjoyable four-wheel-drive experience.
In summary, the transfer case is more than just a component; it is a keystone. Selecting the proper unit necessitates a deep understanding of its operational characteristics and its compatibility with the existing drivetrain. Challenges often arise in adapting older transmissions to modern transfer cases or vice versa. However, meticulous planning and execution at this stage are paramount to ensuring a successful ’73-’87 2WD to 4WD conversion. A careful choice bridges the gap between a mere collection of parts and a truly capable off-road machine.
2. Front Axle Assembly
The transformation of a ’73-’87 GM two-wheel-drive truck into a four-wheel-drive variant hinges critically on the front axle assembly. It’s not merely a bolt-on component, but rather a foundational element that dictates the vehicle’s newfound capabilities. The selection of a suitable front axle embodies a commitment to both functionality and durability. For instance, installing a weak or improperly geared axle can quickly negate the benefits of the conversion, leading to premature wear or even catastrophic failure under stress. Consider the case of a restorer who chose an axle rated below the truck’s gross vehicle weight; after only a few mild off-road excursions, the axle housing warped, rendering the four-wheel-drive system useless. The anecdote serves as a stark reminder: The front axle is not an accessory; it is a structural imperative for a successful 4WD conversion.
Selecting the correct front axle entails assessing several key parameters. Gear ratio is paramount, requiring precise matching with the rear axle to prevent driveline binding. A mismatch can strain the transfer case and diminish handling, particularly on paved surfaces. Furthermore, the axle’s width and mounting points must align with the truck’s frame and suspension geometry. A popular upgrade involves swapping in a Dana 44 or Corporate 10-bolt axle, both known for their strength and availability. These axles, however, often necessitate modifications to the truck’s suspension and steering systems to ensure proper integration. One illustrative example involves a conversion project where the installer neglected to address the steering geometry after installing a wider front axle. This oversight resulted in severe bump steer, making the vehicle challenging and unsafe to drive. Addressing these compatibility issues is therefore crucial for ensuring the conversion enhances, rather than detracts from, the vehicle’s overall drivability.
In summation, the front axle assembly represents a critical link in the chain of a ’73-’87 2WD to 4WD conversion. Its selection demands meticulous attention to detail, encompassing load capacity, gear ratio compatibility, and integration with the truck’s existing systems. Neglecting any of these considerations can lead to compromised performance and reliability. The ultimate success of the conversion rests on the solid foundation provided by a carefully chosen and properly installed front axle assembly, transforming a once-limited two-wheel-drive truck into a capable off-road machine.
3. Suspension Modification
The story of a ’73-’87 GM truck converted from two-wheel-drive to four-wheel-drive is, in many ways, a story of transformed expectations. While the transfer case and front axle grab immediate attention, suspension modification silently dictates the conversion’s long-term viability. It is the unsung hero, preventing what could easily become a tale of woe. Picture the freshly converted truck, boasting a gleaming new front axle and transfer case, but still riding on the original two-wheel-drive suspension. The front end, burdened by the additional weight of the new components, sags noticeably. The truck’s stance is awkward, the handling unpredictable, and the lifespan of the new axle is drastically shortened due to improper angles. This scenario, unfortunately, is not hypothetical; its a common pitfall when suspension modification is treated as an afterthought, rather than an integral part of the conversion.
The core challenge lies in adapting the suspension system, designed for two-wheel-drive, to the demands of four-wheel-drive. The additional weight of the front axle and transfer case requires stiffer springs to maintain proper ride height and prevent premature wear on other components. Furthermore, the need for increased articulation off-road often necessitates longer shocks and potentially, modifications to the suspension mounting points. Ignoring these needs can have serious consequences. For example, a ’78 K10 conversion project suffered repeated front axle failures until the owner realized the original two-wheel-drive springs were allowing excessive axle wrap during off-road use. Upgrading to heavier-duty springs, designed for a four-wheel-drive application, resolved the issue and significantly improved the truck’s off-road performance. The decision to lift the vehicle during the conversion adds another layer of complexity. While a lift kit can provide increased ground clearance, it also alters the steering geometry and driveline angles, potentially leading to bump steer or driveline vibrations if not addressed correctly.
In essence, suspension modification is not merely about achieving a lifted stance; it’s about carefully re-engineering the truck’s handling characteristics to accommodate the demands of four-wheel-drive. Its about ensuring the truck rides level, handles predictably, and can withstand the rigors of off-road use without damaging critical components. Neglecting this aspect transforms the conversion from a well-engineered upgrade into a potential liability. The properly executed suspension modification, in contrast, provides the foundation for a durable, capable, and enjoyable four-wheel-drive experience.
4. Driveshaft Compatibility
Driveshaft compatibility in the context of a ’73-’87 GM 2WD to 4WD conversion is often a harsh lesson learned, not a foregone conclusion. The conversion kit promises four-wheel-drive capability, but the reality often hinges on seemingly minor details, among which the driveshaft stands prominently. A driveshaft too short renders the front axle useless, while one too long invites catastrophic damage to the transfer case. An installer, eager to finish a K5 Blazer conversion, overlooked the measurements and forced a driveshaft that was clearly too long. Within a few miles, the transfer case housing cracked, spilling fluid and rendering the newly installed four-wheel-drive system inoperable. This anecdote underscores the simple truth: driveshaft compatibility is not an option; it’s a prerequisite.
The complexities arise from several factors. The placement of the new front axle, dictated by the chosen suspension modifications, directly influences the required driveshaft length. Similarly, the selected transfer case affects the driveshaft’s spline count and u-joint size. Ignoring these variables leads to mismatched components, resulting in vibrations, premature wear, and, at worst, component failure. A common scenario involves using a driveshaft salvaged from a later-model truck, assuming it will fit. However, subtle differences in frame dimensions or suspension geometry can render the driveshaft incompatible, leading to persistent vibrations and a compromised driving experience. The solution often lies in custom driveshaft fabrication, tailored to the specific dimensions of the converted vehicle. This ensures proper fitment and minimizes the risk of driveline issues.
In summary, driveshaft compatibility is a non-negotiable aspect of a successful ’73-’87 2WD to 4WD conversion. It demands careful measurement, attention to detail, and a willingness to invest in custom solutions when necessary. The consequences of overlooking this seemingly minor detail can be severe, ranging from annoying vibrations to catastrophic component failure. By prioritizing driveshaft compatibility, the installer ensures the converted truck not only achieves four-wheel-drive capability but also maintains its reliability and drivability for years to come. It is a reminder that success often lies not in grand gestures, but in meticulous attention to the smallest details.
5. Steering System Integration
The narrative of a ’73-’87 GM 2WD to 4WD conversion is not merely about bolting on a new axle; it’s a nuanced tale of adapting legacy systems to newfound demands. Steering system integration stands as a critical, often underestimated chapter. A straightforward axle swap without considering steering dynamics risks turning a classic truck into an unpredictable, even dangerous machine. Imagine the scenario: the freshly converted truck rolls out of the garage, sporting its new four-wheel-drive hardware. The owner, eager to test its capabilities, takes it for a spin. However, the first turn reveals a disconcerting reality: the steering is heavy, unresponsive, and plagued by bump steer. The truck wanders erratically, demanding constant correction. This experience, far from the envisioned off-road adventure, is a direct consequence of neglecting steering system integration. The original two-wheel-drive steering linkage, designed for a lighter front end and different suspension geometry, is simply inadequate for the demands of the new four-wheel-drive system.
Consider the engineering challenges. The installation of a front axle inherently alters the vehicle’s steering geometry, particularly the relationship between the steering box, pitman arm, and tie rods. The result can be a dramatic increase in bump steer, a phenomenon where the steering wheel jerks violently in response to bumps in the road. This not only compromises handling but also places undue stress on the steering components, potentially leading to premature failure. The solution often involves a combination of modifications. Dropped pitman arms correct steering angles, while cross-over steering systems improve handling by eliminating the factory push-pull setup. In one documented case, a ’76 K10 conversion project suffered from severe bump steer until the owner invested in a high-steer kit, which relocated the tie rod ends above the leaf springs. This modification dramatically improved the truck’s handling and restored its stability on both paved and unpaved surfaces. The decision to lift the vehicle during the conversion further complicates matters, exacerbating existing steering geometry issues. Longer shocks and springs necessitate corresponding adjustments to the steering linkage to maintain proper alignment and prevent binding.
In essence, steering system integration is more than just ensuring the steering wheel turns the wheels; it’s about preserving, or even enhancing, the vehicle’s handling characteristics in the face of significant mechanical changes. Neglecting this aspect transforms the conversion from a well-engineered upgrade into a potential safety hazard. A properly integrated steering system, on the other hand, ensures the converted truck remains responsive, predictable, and enjoyable to drive, both on and off the road. It’s a crucial reminder that a successful conversion is not just about adding four-wheel-drive; it’s about harmonizing all the vehicle’s systems to create a cohesive and reliable machine.
6. Brake System Adaptation
The tale of a ’73-’87 GM truck undergoing a 2WD to 4WD conversion is incomplete without a careful examination of brake system adaptation. The allure of increased traction and off-road prowess often overshadows the crucial need to ensure adequate stopping power. The reality is simple: adding a front axle increases the vehicle’s weight and changes its weight distribution, demanding a corresponding upgrade to the braking system. A failure to adapt the brakes is not just an oversight; it’s a gamble with safety. The converted truck, burdened by the additional weight of the four-wheel-drive components, may struggle to stop in emergency situations, increasing the risk of accidents. The original brake system, designed for a lighter two-wheel-drive configuration, is simply overmatched by the demands of the heavier, more capable vehicle. This imbalance is further amplified when larger tires are installed, increasing the rotational inertia that the brakes must overcome.
The adaptation process often involves a multi-faceted approach. Upgrading to larger brake rotors and calipers provides increased surface area and clamping force, improving stopping power. Swapping to a master cylinder with a larger bore volume ensures adequate hydraulic pressure to actuate the larger calipers. A ’77 K5 Blazer conversion project, initially plagued by poor braking performance, found a solution by upgrading to a one-ton master cylinder and installing disc brakes on the rear axle. This combination dramatically improved the Blazer’s stopping power and restored driver confidence. Proportioning valves also play a critical role, adjusting the brake bias between the front and rear axles to prevent premature lockup. A properly adjusted proportioning valve ensures that the front and rear brakes work in harmony, maximizing stopping power without compromising stability. Furthermore, the increased stress on the braking system necessitates a thorough inspection and potential replacement of brake lines and hoses. Old or deteriorated lines can rupture under pressure, leading to a complete brake failure.
In conclusion, brake system adaptation is an indispensable element of a safe and successful ’73-’87 2WD to 4WD conversion. It’s a matter of physics: increased weight demands increased stopping power. Neglecting this crucial step transforms the conversion from a well-intentioned upgrade into a potential liability. By meticulously adapting the braking system to the new demands of the four-wheel-drive configuration, the installer ensures the converted truck not only conquers challenging terrain but also maintains its safety and reliability on the road. It’s a reminder that true performance is not just about going; it’s about stopping too.
7. Frame Reinforcement
The conversion of a ’73-’87 GM two-wheel-drive truck to four-wheel-drive is a mechanical undertaking extending beyond simply bolting on new components. It’s a transformation placing increased stress upon the vehicle’s foundational structure: the frame. Frame reinforcement, therefore, ceases to be an optional consideration and becomes a structural necessity. The original frame, designed for the stresses of a two-wheel-drive system, now contends with the added weight of a front axle, transfer case, and the amplified forces generated during off-road use. This creates a scenario where the frame, if left unreinforced, becomes a potential point of failure, leading to compromised handling, structural damage, and potentially unsafe driving conditions. Consider the anecdote of a ’74 C10 converted for off-road use without frame reinforcement. Within a year, cracks began appearing near the steering box mount, a common stress point. Eventually, the frame fractured completely, rendering the truck unusable and necessitating extensive repairs. This illustrates a clear cause-and-effect relationship: insufficient frame strength under the stresses of a 4WD conversion leads to structural failure. Therefore, integrating frame reinforcement into the ’73-’87 2WD to 4WD conversion process is a preventative measure, safeguarding the vehicle’s structural integrity and extending its lifespan.
The specific reinforcement methods vary depending on the intended use of the vehicle and the extent of the modifications. Boxing the frame rails, particularly in areas prone to stress concentration, such as the steering box mount and suspension attachment points, is a common practice. This involves welding steel plates to the open C-channel frame rails, creating a closed box section with significantly increased strength and torsional rigidity. Another technique involves adding crossmembers to stiffen the frame and prevent twisting. This is particularly important for trucks intended for heavy-duty use or off-road applications. Reinforcing the spring perches and shock mounts is also crucial, as these areas are subjected to increased stress due to the modified suspension geometry. One practical application of frame reinforcement involves welding in fish plates around critical stress points. Fish plates are diamond-shaped steel plates that distribute stress over a larger area, preventing localized cracking. The strategic placement of these plates can significantly enhance the frame’s resistance to fatigue and failure. The decision to reinforce the frame, and to what extent, should be based on a thorough assessment of the vehicle’s intended use and the potential stresses imposed by the four-wheel-drive conversion.
In summary, frame reinforcement is not merely an ancillary step in a ’73-’87 2WD to 4WD conversion; it is a fundamental requirement for ensuring the vehicle’s structural integrity and long-term reliability. It addresses the inherent stresses imposed by the conversion process, preventing frame flex, cracking, and ultimately, catastrophic failure. The selection of appropriate reinforcement methods depends on the vehicle’s intended use, but the underlying principle remains constant: strengthen the frame to withstand the increased demands of four-wheel-drive. While the task may present challenges, requiring welding expertise and careful planning, the long-term benefits far outweigh the initial effort. Frame reinforcement is the silent guardian, ensuring the converted truck remains a capable and reliable machine for years to come, a testament to the foresight and thoroughness of the conversion process.

The transfer case, for example, may require wiring for indicator lights or electronic shift controls. The front axle, if equipped with locking differentials, needs wiring for its activation system. Ignoring these requirements is akin to building a house without wiring structurally sound but ultimately uninhabitable.
The challenges stem from the inherent differences between the two-wheel-drive and four-wheel-drive wiring schematics. The original harness may lack the necessary circuits or connectors to accommodate the new components. The installer faces the daunting task of identifying and modifying the existing wiring, adding new circuits, and ensuring proper grounding. A common oversight is the failure to properly insulate and protect the wiring, exposing it to the elements and potential damage. Consider the experience of a ’79 K10 conversion project. The installer, eager to finish the project, spliced into the existing wiring harness to power the transfer case indicator light. However, he neglected to properly seal the connections, and within a few months, corrosion had crept in, causing intermittent electrical problems and ultimately rendering the indicator light useless. This seemingly minor issue underscored a fundamental truth: wiring harness integration is not just about connecting wires; it’s about ensuring the long-term reliability and functionality of the entire system. Moreover, the use of aftermarket components, such as electronic transfer case shifters or axle lockers, further complicates the wiring process. These components often come with their own wiring diagrams and requirements, demanding careful planning and execution to ensure seamless integration with the existing electrical system.
