Product Description

The Timbren GMRCK25DM1.5 Active Off-Road Bump-Stop Kit is built for drivers of heavy-duty Chevrolet and GMC 2500/3500 trucks who need enhanced suspension performance under serious load or travel conditions. While factory bump-stops may bottom out or harshly engage when the vehicle is loaded or used off-road, this kit’s hollow-rubber springs progressively engage to absorb shocks, reduce axle hop and maintain better contact with the road or trail.

Installation is straightforward -the kit mounts directly into the factory rear bump-stop locations and retains normal ride height when the truck is unloaded. When you load heavy gear, tow trailers or tackle rough terrain, the system supports the rear suspension without altering daily-drive comfort. It’s especially useful for owners who experience sag, excessive axle movement or harsh rear bump-stop hits in their ¾-ton trucks.

While this kit significantly improves stability, load control and ride quality, it does **not** increase the vehicle’s Gross Vehicle Weight Rating (GVWR). Always adhere to factory payload and towing limits. Confirm your specific year, trim, engine and drivetrain configuration before ordering.
