Ditch The Factory Rake And Open Up Room For Bigger Tires

GM HD trucks come from the factory sitting nose-down to handle heavy payloads, and while that's fine for hauling, it's the first thing most owners want to correct once they start building their truck. The Axiom Supply Stage 1 Leveling System gives your 2011-2019 Silverado or Sierra 2500HD or 3500HD up to 2 inches of front lift, leveling out that stance and opening up clearance for a 35 inch tire when everything's properly configured. What separates this system from a basic set of torsion keys is the inclusion of front shock extension brackets, which reposition your factory shocks so they continue operating through their full, proper range of travel instead of topping out early. That means you get the leveled look and added clearance without sacrificing ride comfort or accelerating shock wear down the road. The forged torsion keys are re-indexed for additional height while staying within proper torsion bar preload and adjustment range, so you're not putting unnecessary stress on the suspension just to gain lift. Whether your truck is towing during the week or hitting the trail on the weekend, this system holds up to real use. And if you're planning to push your build further, it sets you up perfectly to add Axiom's Heavy-Duty Upper Control Arms down the road.

Engineered Specifically Around 2011-2019 GM HD Suspension Geometry

The Axiom Supply AXGM11STAGE1 is a complete Stage 1 leveling system built specifically for the 2011-2019 GM HD torsion bar suspension platform, covering Silverado and Sierra 2500HD and 3500HD models with standard suspension. At the core of the kit are precision-forged torsion bar keys featuring 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 shock operation throughout the full suspension cycle. This system is designed to work with factory front shocks or OE-equivalent replacements only, and the included shock extensions should never be paired with shocks longer than stock length, as that can compromise travel and overall suspension performance. With the kit properly installed, the truck can accommodate tires up to approximately 35 inches depending on wheel offset and tire dimensions. 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 welding 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 customers looking to maximize suspension geometry and alignment capability, this system pairs directly with Axiom's Heavy-Duty Upper Control Arms featuring true double-shear construction and Grade 12.9 ball joints.
