Features

_x000D_

Complete Stage 2 Suspension Solution – Combines heavy-duty upper control arms, forged torsion leveling keys, and shock spacers into a single system designed to work together for maximum performance and reliability.

_x000D_

True Double-Shear Construction – Built from identical upper and lower 3/16" steel plates that are precision laser cut and hand welded into a single rigid structure. This true double-shear architecture distributes suspension loads evenly while maximizing strength, rigidity, and long-term durability.

_x000D_

Equipped with AX6292 Grade 12.9 Ball Joints – Every kit includes a pair of Axiom Supply AX6292 bolt-on upper ball joints featuring our Grade 12.9 Extreme-Duty Ball Stud technology for exceptional strength, steering precision, and resistance to deformation under heavy loads.

_x000D_

Forged Torsion Leveling Keys – Designed to provide additional front ride height while maintaining proper torsion bar indexing and adjustment range.

_x000D_

Shock Spacer & Extension System – Restores available shock travel after leveling to help maintain ride quality, suspension performance, and shock longevity.

_x000D_

Corrected Suspension Geometry – Restores proper suspension operating angles while improving droop travel and overall suspension performance.

_x000D_

Dual-Position Ball Joint Mounting – Allows the ball joint to be mounted above or below the control arm mounting plate, providing additional flexibility when dialing in alignment settings and suspension geometry.

_x000D_

Precision Laser-Cut Components – Manufactured using computer-designed, laser-cut steel components for exceptional fitment consistency and manufacturing accuracy.

_x000D_

Description

_x000D_

The Axiom Supply Stage 2 Leveling System was developed for GM HD truck owners looking for more than a simple leveling kit. By combining ride height adjustment with suspension correction components, this system delivers improved appearance, increased capability, and long-term reliability.

_x000D_

At the foundation of the system are Axiom Supply forged torsion leveling keys, providing up to 2" of front ride height adjustment to eliminate factory rake and create clearance for larger tire and wheel combinations. To maintain proper suspension performance after leveling, the system includes Axiom Supply shock spacers and extensions that help restore shock travel and preserve ride quality throughout the suspension's operating range.

_x000D_

Unlike basic leveling kits that simply increase ride height, the Stage 2 System addresses the geometry changes created by suspension modifications. Included Axiom Supply Heavy-Duty Upper Control Arms feature a true double-shear construction utilizing identical upper and lower 3/16" steel plates hand welded into a rigid boxed structure. This design distributes suspension loads evenly through the ball joint mounting area while minimizing flex and maintaining alignment integrity under demanding conditions.

_x000D_

Each control arm is equipped with Axiom Supply AX6292 Bolt-On Upper Ball Joints featuring our Grade 12.9 Extreme-Duty Ball Stud technology. Combined with the dual-position ball joint mounting system, installers gain additional alignment flexibility while benefiting from one of the strongest bolt-on upper ball joints available for the GM HD platform.

_x000D_

Whether your truck is used for towing, work, off-road exploration, or everyday driving, the Axiom Supply Stage 2 Leveling System provides the ride height, suspension correction, and component strength required to confidently handle whatever comes next.

_x000D_

Maintenance

_x000D_

Apply 3 pumps of grease to each ball joint during installation.

_x000D_

For continued performance, service each ball joint every 5,000–7,000 miles. Use only the amount of grease necessary to lubricate the joint and avoid over-greasing.
