Description
The Dirt King MT Prerunner Kit is a complete suspension package engineered to deliver the ideal blend of aggressive off-road capability and everyday on-road comfort. It includes 2.5" DCA Coilovers, 2.5" DCA Smooth Body Rear Shocks, Multi-rate Springs, and 4130 Upper Control Arms (UCAs)—developed together to ensure the front and rear suspension systems work in perfect sync.
Unlike most manufacturers, we began by tuning spring rates independently from shock damping to achieve optimal front-to-rear balance and roll control before refining compression and rebound valving. Increased rate allows the progressive-rate rear springs and shocks to work in harmony on-road for a smooth drive while also helping prevent harsh bottom-outs when the terrain gets rough.
Both front and rear shocks feature Dirt King's Dual Compression Adjusters (DCA), with high-speed and low-speed compression knobs for terrain-specific tuning. From trail driving to hauling gear, you’ll get consistent control and comfort both on and off the road.
The 4130 UCAs are built from chromoly tubing for superior strength and durability under extreme conditions. Designed with optimized geometry for improved caster and camber alignment, they deliver smooth, predictable handling both on and off the road. Each arm is equipped with heavy-duty ProBearing ball joints and maintenance-free SilentSpin bushings, offering maximum articulation, noise-free performance, and long-term reliability.
