Description

The Axiom Supply Stage 1 Leveling System is the ideal suspension upgrade for owners looking to eliminate factory rake while preserving the ride quality, suspension travel, and reliability engineered into today's GM HD trucks.

From the factory, Silverado HD and Sierra HD trucks feature a forward rake designed to accommodate heavy payloads and towing. While practical, this stance reduces front-end clearance and limits the overall appearance of the truck. The Axiom Stage 1 System raises the front suspension up to 2", creating a level stance while increasing approach angle and providing additional room for larger tire and wheel combinations.

At the core of the system are Axiom Supply precision-forged torsion bar keys featuring an optimized re-index that delivers additional ride height without overextending the factory torsion bar adjustment range. This engineered approach provides dependable lift while maintaining predictable suspension characteristics and long-term reliability.

Unlike basic torsion key leveling kits, the Axiom Stage 1 System also includes front shock extension brackets designed to relocate the factory shock absorbers and preserve proper suspension travel. Maintaining the factory shock operating range helps reduce unnecessary stress on suspension components while delivering a comfortable, controlled ride on the highway, at the job site, or off the beaten path.

Manufactured for precise fitment and long-term durability, every component is engineered specifically for the 2020-2026 GM HD platform. The forged torsion keys feature a corrosion-resistant black powder-coated finish, while the included hardware is built to withstand years of demanding service.

For customers seeking the highest level of suspension performance, the Stage 1 System pairs perfectly with the Axiom Supply Heavy-Duty Upper Control Arm System, creating a complete suspension solution that improves alignment capability, suspension geometry, and overall front-end performance.

Whether your truck is built for towing, hauling, work, or weekend adventure, the Axiom Supply Stage 1 Leveling System delivers the balanced stance, increased clearance, and confidence expected from a premium leveling system.
