The 14 Bolt BACKBONE Truss from Artec Industries is a full-length top truss for the GM/Dodge 14-bolt full-float rear axle, the go-to housing for serious one-ton builds. Rather than reinforcing only the link-mount area, it runs the entire span of the axle to fight bending and keep your gear pattern true under big-tire, high-speed abuse. If you are building a 14-bolt for a Jeep, buggy, or heavy tow rig, this is the backbone that keeps the housing straight.
Key Features
- 1/8" thick mild steel truss top with internally jigging gussets, precision CNC cut and bent for repeatable fitment.
- Triangular profile so you are not dragging boxy edges over rock, while adding structural rigidity to the housing.
- Spans the entire length of the axle — brake flange to brake flange — for complete reinforcement of the tubes, not just the link area.
- Internal gussets carry the load; the hardware simply holds the assembly together for welding.
- Designed for vehicles that hit obstacles at speed, where a short center truss leaves the tube ends exposed.
Fitment & Compatibility
Fits GM and Dodge 14-bolt full-float rear axles built to a 68" WMS (wheel-mounting-surface) width. Narrower axles will require trimming the ends of the truss to fit. This is a weld-on reinforcement intended for custom axle builds and one-ton swaps rather than a specific model year; verify your housing width before ordering. It pairs naturally with an Artec 14 bolt Pinion Guard with Bridge to protect the third member.

Frequently Asked Questions
What axle does the 14 Bolt BACKBONE Truss fit?
It is built for the GM/Dodge 14-bolt full-float rear axle at 68" WMS width. Narrower housings can be run by trimming the ends of the truss.
How is it different from a short center truss?
The BACKBONE spans the full length of the housing flange-to-flange, so the tube ends are supported too. That matters most for rigs that take hits at speed, where a short truss leaves the outer tubes unbraced.
Does it require welding?
Yes. This is a weld-on truss. The internal jigging gussets set the alignment and carry the load, so a competent MIG welder and full-penetration welds are recommended.
Will it clear my springs and mounts?
The low, triangular profile is designed to shed rocks and reduce interference, but always mock up against your spring perches, link mounts, and pinion guard before final welding.
