Description

The Axiom Supply Stage 1 Leveling System is the ideal solution for GM HD truck owners looking to eliminate factory rake while preserving the ride quality and suspension performance their truck was designed to deliver.

At the heart of the system are precision-forged torsion bar keys featuring a revised index that provides up to 2" of front lift without overloading the torsion bar adjustment range. The result is a level stance, increased ground clearance, and additional room for larger tire and wheel combinations while maintaining predictable handling characteristics.

Unlike leveling kits that simply raise the front suspension, the Axiom Supply Stage 1 System also includes front shock extension brackets designed to relocate the factory shock absorbers and preserve proper suspension travel. By maintaining the factory operating range of the shocks, the system helps deliver a comfortable ride while reducing unnecessary stress on suspension components.

Engineered specifically for GM torsion bar suspension platforms, every component is manufactured for precise fitment and long-term durability. The forged torsion keys feature a corrosion-resistant black powder-coated finish, while the included hardware is designed to provide years of dependable service in demanding work and off-road environments.

For customers planning more aggressive leveling or larger tire packages, the Stage 1 System serves as the ideal foundation and pairs perfectly with Axiom Supply Heavy-Duty Upper Control Arms for additional suspension geometry correction and alignment capability.

Whether your truck is built for towing, work, daily driving, or weekend adventures, the Axiom Supply Stage 1 Leveling System provides the balanced stance, increased clearance, and suspension performance expected from a premium leveling solution.
