Stiffer Spring Rates
Achieving increased ride height typically necessitates the use of stiffer springs. These springs, designed to support the vehicle at a higher stance and resist bottoming out during off-road excursions, inherently transmit more impact force to the vehicle’s frame and occupants. On paved roads, this translates to a firmer ride, characterized by increased sensitivity to bumps and imperfections. The once-supple suspension now communicates more of the road’s texture directly to the cabin.
-
Altered Shock Absorber Characteristics
To control the increased spring rate and maintain stability, lift kits often include shocks with different damping characteristics than the factory-equipped units. These shocks may be valved to provide greater resistance to compression and rebound, leading to a less compliant ride. While this increased firmness can improve handling and control, it also reduces the suspension’s ability to absorb smaller bumps and vibrations, resulting in a harsher ride quality.
-
Increased Body Roll (Potentially)
Though counterintuitive, simply adding height does not ensure better control. Adding a system shifts the center of gravity. Without proper control, such as sway bar modification or appropriate shock valving, this increased height can cause additional body roll. This can translate to less stability when turning and less comfort in high speed situations.
-
Noise, Vibration, and Harshness (NVH)
The installation of a suspension kit can alter the vehicle’s NVH characteristics. Stiffer components and altered geometry may introduce new sources of noise, vibration, and harshness into the cabin.
