Zone Offroad leaf springs are a 5-leaf pack with anti-friction pads and center leaf spacer plates between each leaf. This design significantly decreases leaf pack internal friction for a smooth and consistent spring rate. The 4" lift kit includes front leaf springs with bushings and u-bolts, steering arm, front & rear brake line relocation brackets, front & rear yellow zinc plated u-bolts with high nuts and washers, a rear block and 4 Zone Hydro shocks. Shock boots sold separately. If your vehicle came with a front sway bar, the Zone unique shackle sway bar link design is recommended.
