Level The Stance And Make Room For The Tires You Actually Want

GM HD trucks are built with a forward rake straight from the factory, which makes sense for towing heavy loads but leaves the front end sitting lower than most owners want. The Axiom Supply Stage 1 Leveling System takes care of that on your 2020-2026 Silverado HD or Sierra HD, delivering up to 2 inches of front lift to level out the stance and open up clearance for tires up to 35 inches when properly configured. What makes this system stand apart from a basic torsion key kit is the included front shock extension brackets, which reposition your factory shocks so they keep working through their full range of travel instead of topping out early. That means you get the leveled look and added clearance without giving up ride quality or wearing out your shocks prematurely. The forged torsion keys are precisely re-indexed to deliver that extra height while staying within the factory torsion bar's preload and adjustment range, so nothing is getting pushed past its intended limits. Whether your truck is towing during the week or exploring backroads on the weekend, this system holds up to real use without compromise. And if you're planning to build further, it's the ideal foundation before stepping up to Axiom's Heavy-Duty Upper Control Arms.

Precision Engineered Suspension Geometry

The Axiom Supply AXGM20STAGE1 is a complete Stage 1 leveling system engineered specifically around the suspension geometry of the 2020-2026 Silverado HD and Sierra HD platform, covering 2500HD and 3500HD models. At the core of the kit are precision-forged torsion bar keys with an optimized re-index that delivers up to 2 inches of additional front ride height while maintaining proper torsion bar preload and staying within the factory adjustment range. Paired with the keys are front shock extension brackets, which relocate the factory shock absorbers to preserve suspension travel and maintain proper operation throughout the entire range of motion. This system is designed to work with factory front shocks or OE-equivalent replacements only, and the included shock extensions should never be installed with shocks longer than stock length, as that can compromise travel and suspension performance. With the kit properly installed, most applications can accommodate tires up to 35 inches depending on wheel offset and tire width. Every component features a durable black powder-coated finish for long-term corrosion resistance, and installation is a direct bolt-on process using factory mounting locations with no cutting or drilling required. The complete kit includes the torsion keys, shock extension brackets, all necessary installation hardware, and detailed instructions, and it's backed by Axiom Supply's lifetime warranty against manufacturer defects, premature wear, or breakage. For maximum suspension performance, this system pairs directly with Axiom's Heavy-Duty Upper Control Arm System.
