14 Bolt Pinion Truss Bridge

14 Bolt Pinion Truss Bridge

Heavy-duty reinforcement where 14 Bolts need it most.

The 14 Bolt axle is a proven platform, but when you're putting down big horsepower, the factory plug welds on the axle tubes can become a failure point. The RuffStuff Pinion Truss Bridge strengthens that area by tying your axle truss directly into the pinion support—greatly improving structural rigidity and reducing the risk of tube separation under extreme stress.

This bridge is designed to pair with our 14 Bolt Truss but is fully adaptable to most aftermarket or custom-built trusses. The elongated slots on the bridge allow for multiple mounting options—including with or without a pinion guard.
