Timbren Active Off-Road bump stops for 2017+ Chevrolet Colorado ZR2 rear suspension replace conventional stops with progressive-rate rubber springs that absorb axle energy instead of creating a hard stop. They preserve usable suspension travel, produce smoother, quieter engagement when bottoming out, and are backed by Timbren’s Lifetime Warranty plus a 100-day money-back guarantee for off-road upgrades.
