Skyjacker aluminum suspension lift kit.

The biggest determining factors in ride quality and suspension performance are coil springs and shocks. Skyjacker specifically engineered a progressive 2-stage dual rate long travel coil. 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. Shocks are a key link in-between the chassis and the moving parts of your suspension. Their key role is to optimize your suspension by keeping your tires in contact with the terrain. Front and Rear Bump Stop Spacers bolt onto the axle bump pads and keep the suspension travel safely in check. Comes complete with Bushings and High-Grade Mounting Hardware.

A suspension lift raises ride height to clear larger tires; component kits vary in what they include, so check the parts list.
