Here is the ultimate for strengthening the rear axle of a 2011-15 Ford Superduty. This modular truss system allows it to be installed as a top only, rear only or for the strongest possible installation, both!
The top section of this is fabricated from 1/4" and the rear from 3/16". Rear diff cover is built from heavy duty 3/8" plate. All components are 100% CNC laser cut and bent for excellent quality and fitment.
The rear diff cover (if ordered) will come fully welded and CNC decked/drilled to ensure proper fitment. If diff cover by itself is ordered, no truss is included. None of the trusses come welded and some minor fitment work is to be expected.
It should also be noted that because the center sections have areas that can/will be welded to the factory cast differential housing and the fact that the axle is being welded in general, this needs to be done by a competent welder/shop.
PMF is not responsible for damage to your axle/differential!
