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. Front and Rear Bump Stop Spacers bolt onto the axle bump pads and keep the suspension travel safely in check. Rear Track Bar Lower Axle Mount Bracket re-centers rear axle and restores the Wranglers distinctive suspension handling characteristics. Complete with All High-Quality Grade Mounting Hardware.
