Features

Complete Stage 1 Leveling System – Includes forged torsion bar keys and front shock extension brackets engineered to work together as a complete suspension leveling solution.

Forged Torsion Keys – Precision-forged and re-indexed to provide up to 2" of front ride height while maintaining factory torsion bar engagement and adjustment range.

Maintains Proper Shock Travel – Included shock extension brackets reposition the factory shock absorbers to preserve suspension travel and prevent the shock from becoming the suspension's limiting component.

Improved Stance & Ground Clearance – Eliminates the factory nose-down rake while increasing approach angle and front-end clearance for improved capability on and off-road.

Additional Tire Clearance – Creates room for larger tire and wheel combinations without compromising everyday drivability.

Durable Powder-Coated Finish – Premium black powder coating provides excellent corrosion resistance and long-term durability in harsh environments.

Engineered for GM 1500 4WD Trucks – Designed specifically around the geometry and suspension characteristics of 6-lug GM 1500 torsion bar front suspension systems.

Direct Bolt-On Installation – Installs using factory mounting locations with no cutting, welding, or permanent modifications required.

Description

The Axiom Supply Stage 1 Leveling System is the ideal solution for 4WD GM 1500 truck and SUV owners looking to eliminate factory rake while preserving the ride quality and suspension performance their vehicle was designed to deliver.

From the factory, many GM 1500 trucks and SUVs sit lower in the front to accommodate payload and towing requirements. While functional, this forward rake limits tire clearance and gives the vehicle an uneven stance. The Axiom Stage 1 System raises the front suspension up to 2", creating a more balanced appearance while increasing ground clearance and improving front-end clearance for daily driving, towing, trail use, and weekend adventure.

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

Unlike basic 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 6-lug GM 1500 4WD 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 shock extensions and hardware are built for dependable service in real-world driving conditions.

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 work, towing, daily driving, or off-road use, the Axiom Supply Stage 1 Leveling System provides the balanced stance, increased clearance, and suspension performance expected from a premium leveling solution.
