Build your 14 bolt to survive anything — a low-profile, heavy-duty truss system for serious Squarebody off-road and linked rear axle builds.

This is the CFM Industries GM 14 Bolt Full Float axle truss system, built to strengthen and modernize the rear axle on your Squarebody Chevy and GMC build. The GM 14 bolt full-float is already one of the toughest axles GM ever put under a truck — this truss system takes that foundation and makes it ready for hard wheeling, big tires, and a linked suspension setup.

Whether you're triangulating a 4-link, crawling rocks, or building a no-compromise off-road rig, this system gives your housing the strength and the mounting points to do it right — without a bulky truss hanging down to catch every obstacle.

Why It Works

• Built for the GM 14 bolt full-float — purpose-made for one of the strongest axles under any Squarebody.
• Low-profile design — adds serious strength without hanging down to snag on the trail.
• Link-ready — set up for triangulated 4-link and linked suspension builds.
• Heavy-duty fabrication — reinforces the housing for big power, big tires, and hard hits.
• Weld options to fit you — have us weld as much as we can, or weld it all yourself.
