Dirt King Fabrication Long Travel Race Kit for Chevy Silverado / GMC Sierra 1500 DK-632909

This suspension system was developed for the most extreme off-road terrain. The long travel race kit is capable of 17.5” of travel and can accept up to a 37” tire. Dirt King has perfected the suspension geometry by relocating the upper control arm mounts and modifying the outer pivot locations on the spindle. With these changes they were able to achieve twice the amount of travel compared to stock and eliminate bump steer throughout the suspension cycle. The kit accepts 2.5 x 10” coil overs, 3.0 x 10” bypasses, and 2.0 X 2.0 bump stops (NOT INCLUDED) for superior suspension dampening. This kit is constructed using parts commonly found on trophy trucks such as massive FK 1.5" uniballs and JMX series heims. The result is a suspension system with reliable performance and off road handling that will exceed all expectations.
