Stop your tubes from spinning with the Artec Industries 8.8 Truss Bridge. The bridge will connect your Modular 8.8 Truss to the third member of your axle, adding more resistance to spinning axle tubes. The Artec Industries 8.8 Truss Bridge welds to the truss itself and bolts onto the casting. Depending on the pinion angle, the truss side of the bridge might need trimming. Hardware isn't included.
