This is the key to fixing wheel hop / limit diff travel!
It simply replaces the existing single-bushing bracket bolted to the rear of the differential with a new billet aluminum bracket designed to add a second bushing
Note* The single bushing option is suggested if you have aftermarket polyurethane bushings already or just want to add one bushings. We suggest a full set of bushings if you have oem diff bushings. Powerflex bushings are the best we have used and it is what we included.
new hardware is included also
