This modification component replaces the factory suspension with a system utilizing four links to locate the axle. These kits typically include adjustable link arms, brackets for mounting to the frame and axle, and necessary hardware. This aftermarket upgrade is primarily intended for off-road performance enhancement.
The benefits of this modification include improved articulation, allowing the vehicle’s wheels to maintain better contact with uneven terrain. This, in turn, increases traction and control. Furthermore, the adjustable nature of the components allows for fine-tuning of the suspension geometry to optimize handling and ride quality. Historically, such systems have been adopted in various forms of motorsports, including rock crawling and desert racing, and are now available for popular truck models to improve their off-road capabilities.
