Skyjacker specifically engineered a progressive variable rate coil spring, distinctively a 2-stage dual rate long travel coil. Spring rate progression is from a first Flex Rate to a second Ride Rate. First Flex Rate stage delivers a comfortable ride with the ability to flex/expand during full articulation as the suspension drops (full droop). This keeps the coil springs seated in the upper coil mount/bucket and the tires in contact with the terrain. Second Ride Rate stage only engages after compression past Flex Rate. Includes a Pair of Front and a Pair of Rear Dual Rate Long Travel Coil Springs. Front and Rear Bump Stop Spacers bolt in between the upper frame and OEM bump stops. Correct bump keeps the suspension travel safely in check. Rear Track Bar Lower Axle Mount Bracket mounts directly to the rear axle housing to correct the track bar angle. The track bar bracket re-centers the rear axle and improves suspension handling and a lower roll center. Lower roll center means less side-to-side sway. Eccentric alignment cam bolts correct caster and pinion angles (front lower axle and rear upper front). Comes complete with Bushings and High-Grade Mounting Hardware.
