Description

The Axiom Supply Stage 1 Leveling System is the ideal first step in upgrading the stance and capability of your 2011-2019 GM HD truck.

Factory rake is designed to accommodate heavy payloads, but it often leaves the truck with an uneven appearance while limiting front-end clearance for larger tires. The Axiom Stage 1 System raises the front suspension up to 2", creating a balanced stance, improving approach angle, and increasing clearance for today's larger wheel and tire combinations.

At the center of the system are precision-forged torsion bar keys featuring an optimized re-index that delivers additional ride height while maintaining proper torsion bar geometry and adjustment range. This engineered design allows the suspension to achieve increased lift without compromising long-term reliability.

Unlike basic torsion key leveling kits, the Axiom Supply Stage 1 System includes front shock extension brackets that reposition the factory shock absorbers to maintain proper suspension travel. Preserving the factory shock operating range helps maintain ride comfort, improves suspension performance, and reduces unnecessary stress on the shock absorbers and surrounding suspension components.

Every component is engineered specifically for the 2011-2019 GM HD platform and manufactured to deliver exceptional fitment, durability, and long-term corrosion resistance. The forged torsion keys receive a durable black powder-coated finish, while the included installation hardware is designed to provide dependable service in demanding work, towing, and off-road environments.

For customers planning to maximize suspension performance, the Stage 1 Leveling System is the ideal foundation for upgrading to the Axiom Supply Heavy-Duty Upper Control Arm System featuring True Double-Shear Construction and AX6292 Grade 12.9 Ball Joints. Together, they provide improved suspension geometry, increased alignment capability, and enhanced front-end durability.

Whether your truck spends its life towing, hauling, working, or exploring off-road, the Axiom Supply Stage 1 Leveling System delivers the balanced stance, additional clearance, and confidence expected from a premium suspension upgrade.
