4 Inch Component Box With Dual Rate Long Travel Coil Springs with Lower Links 03-06 Jeep Wrangler TJ Skyjacker

Skyjacker specifically engineered a progressive variable rate coil spring, distinctively a 2-stage dual rate long travel coil. The first Flex Rate stage delivers a comfortable ride with the ability to flex/expand during full articulation. The second Ride Rate stage only engages after compression past the Flex Rate, resulting in a smoother ride. This kit provides a 4-inch lift and includes front and rear dual rate long travel coil springs, longer replacement front and rear lower control link arms, front and rear bump stop spacers, front and rear extended length sway bar end links, a tubular transfer case lowering kit, a drop pitman arm, and a rear track bar lower axle mount bracket.
