The "BTF Model 20 Diff Ring for Truss" is laser-cut from 3/8" high-strength steel plate. This is the ring that we use with our line of "Kryptonite" Diff Covers. It could be used to build your own diff cover or it could be used as a large washer to keep your stock cover from peeling-up when it is dragged over a rock. Note: The ring may require minor grinding to clear the stock cover.
This ring was designed for use with our truss systems to reinforce the truss to the cover. It could be used for other purposes.
