We use the latest valving technology that works in stages based on the vehicle’s speed to provide optimal driving control. Additionally, the Teflon bonded piston seal helps reduce friction and keep temperatures low, ensuring the stability of the valve. Our springs are heat-treated and powder-coated to ensure durability and corrosion resistance in harsh conditions. The steel rod is micro-polished with double chrome plating to increase corrosion resistance and extend lifespan. Driving More Comfortable. Spring seats insulated to springs to ensure quiet and comfortable ride quality. Neoprene boots and bump stops when applicable. Constant rate front coil springs help improve stability and recover or maintain ride height. Replacing this new shock absorber can greatly improve your ride comfort, drivability and tire grip. Superior Driving Experience and Easy Installation. We’ve included isolators between the spring seat and springs to reduce noise and enhance comfort. Moreover, the shock absorber set comes pre-assembled with the spring, boot, bumper kit, spring seat, isolator, and shock mount. It can be quickly installed on your vehicle without the need for special tools. Any question, please don’t hesitate to let us know.
