// 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, and Billet Upper Control Arms—developed together to ensure the front and rear suspension systems work in perfect sync. 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 Billet UCAs are precision-machined from 6061 aluminum, with improved caster settings, re-engineered pivot angles, and an adjustable inner pivot system. They are available with either maintenance-free SilentSpin bushings or ¾” chromoly rod ends, both paired with heavy-duty Probearing ball joints for strength and articulation. Choose the amount of lift that matches your desired ride height, with options including a 2" front lift to level with factory rear springs or a 3.5" front lift paired with a 1.5" rear lift, complete with Eibach springs.
