CFMi - GM 14 Bolt Full Float Axle Truss System for Squarebody Chevy Trucks and Off-Road Builds

CFM Industries GM 14 Bolt Full Float Axle Truss System

Strengthen your rear axle setup with this low-profile GM 14 bolt full-float axle truss system designed for serious off-road and custom suspension builds. Engineered for dual triangulated 4-link configurations, this system provides the strength, rigidity, and link mounting structure needed for high-articulation suspension setups.

Built from formed plate steel with a boxed truss design and massive integrated pinion protection, this setup is designed to handle hard off-road use, large tires, and high-load suspension systems.

Why This Upgrade Works

A linked suspension setup is only as strong as the axle structure supporting it. This truss system reinforces the axle housing, improves link mounting strength, and adds serious pinion protection for demanding off-road use and high-articulation suspension systems.
