RKTunes - Diff Lock

Looking to drift or drag race your car? You need to lock your diff for more consistent results!

Effortlessly lock your BMW/Supra differential with our diff lock. We have designed a part that replaces your original diff motor with a solid billet aluminum block and heat-treated steel shaft. Easy to install and remove for cars that are driven both on and off the track.

No electronics to break or malfunction, reliability where you need it most.
