Active Off-Road Bumpstops provide off-road enthusiasts greater control over their vehicles' suspension travel. Using progressive-rate springs means that instead of a hard stop at the end of axle travel the axle energy will be absorbed when bottoming-out producing smooth, predictable and quiet axle engagement and disengagement. Unlike OEM bump stops, Active Off-Road Bumpstops are made from natural rubber. Just like our Timbren SES line, Active Off-Road Bumpstops carry a lifetime warranty and a satisfaction guarantee.Installation InstructionsInstallation Instructions Absorbs Energy and Cushions Road Shock Smooth Engagement and Disengagement Maintain Full Suspension Travel Enhance Suspension Performance Stronger than OEM Bump stops 100 Day Money Back Guarantee Satisfaction Guarantee Easy Installation Lifetime Warranty
