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 the Timbren SES line, Active Off-Road Bumpstops carry Timbren's Lifetime Warranty and a 100-Day Money Back Guarantee. ABSGMFK replaces the rear OEM bump stops on the 2015-current Chevy Colorado/ GMC Canyon. Included in this kit is a U-Bolt flip kit to allow for more ground clearance. Upgrade to Active Off-road Bumpstops and experience the difference.
