Finally A Bump Stop Built For Trucks That Sit Leveled

If you've leveled your GM HD truck, you already know factory rubber bump stops weren't designed for the increased suspension angle that comes with it. They crack, compress, and lose their shape fast, and once that happens you start feeling every hard hit straight through the chassis. Axiom Supply built this bump stop specifically to solve that problem, and it's the only truly molded polyurethane version made for these trucks rather than a repurposed universal part. The team spent real time dialing in the exact polyurethane durometer needed, firm enough to control suspension movement under heavy-duty loads, but compliant enough to actually absorb impact instead of just transferring it into the cab. These bump stops are meant to stay in light contact with the lower control arm at ride height on a leveled truck, and that's intentional, not a fitment issue. That contact is what dampens unwanted suspension movement and keeps things from feeling harsh over rough roads. Whether you're daily driving, towing, or running your leveled truck off-road, this kit protects your front suspension from repeated hard bottom-outs. It's a small part that makes a noticeable difference in ride quality.

Purpose Engineered Construction For Leveled Suspension Geometry

The Axiom Supply AXGM201426 is a molded polyurethane front lower bump stop kit engineered specifically for 2001-2010 GM Silverado and Sierra 2500HD and 3500HD trucks running a leveling kit or other modification that increases front suspension angle. This kit is not intended for stock-height trucks, since the design relies on that increased angle to function correctly. Each bump stop is fully molded as a single, application-specific component, which gives it consistent shape and density compared to basic rubber replacements that deform and crumble over time. Embedded directly into each bump stop during the molding process is a gold-zinc-plated Grade 8 mounting stud, eliminating loose internal hardware or improvised fastening methods found in lesser aftermarket parts. Each stud is secured with a nyloc flange nut, which provides even clamping pressure while the nylon insert resists loosening under repeated vibration and suspension cycling. On a leveled truck, these bump stops are designed to make contact with the lower control arm at ride height, providing progressive support as the suspension compresses and helping dampen oscillation rather than allowing harsh metal-to-metal contact. The kit is sold as a matched pair, covering both the left and right side of the front suspension in a single purchase. Every AXGM201426 kit is backed by Axiom Supply's lifetime warranty against manufacturer defects, premature wear, or breakage.
