Fxx M3/M4 Dual Differential Mount

When adding power or tracking your Fxx M3/M4, you can get play in the rear end.  Stiffen it all up with Revshift's billet aluminum dual differential mount.  This kit includes a second rear bushing and dual mount bracket that adds a mounting point to the subframe.  The polyurethane bushings mount the differential eliminating wheel hop and improving the vehicles handling.  The two piece bushing design sandwiches the subframe not only locking everything in place, but making it easier to remove the bushings if needed.  The bushings won't shift while driving like other one piece designs.

The dual mount bracket was CAD designed for strength and the best fitment on the market.  This kit is entirely made in the USA from 6061 billet aluminum.
