Skyjacker's 4" Component Box with Dual Rate Springs for Jeep Wrangler JK is an excellent way to add high-grade suspension products and springs to improve off-road performance. Heavy-duty coils offer dual spring rates which deliver a comfortable ride with the ability to flex and expand during full articulation, keeping the coil springs seated in the upper coil mount/bucket and tires in contact with the terrain. Also included are Front and Rear Bump Stop Spacers which bolt onto the axle bump pads and keep the suspension travel safely in check, adjustable front track bar, as well as front and rear bump stop spacers that are beefier and more durable than factory versions. Kit features all hardware necessary for installation, as well as pressed-in bushings and comes with a limited lifetime warranty.
