Ford 8.8 Swap Bundle

Everything you need to convert to an indestructible yet lightweight Ford 8.8 setup in your 135i, 335i or M3. Features carbon clutch LSD, billet stubs, and single piece aluminum driveshaft.


This kit makes it simple to install one of the most durable drivetrains into your 135i, 335i or M3. This kit is a great option to get rid of the terrible open differentials that come standard in the 135i/335i and the lousy M-Variable differential in the E9X M3. No more one-wheel peels! You'll be able to light up both tires like a proper hoon with this kit. This system is right at home drifting, drag racing or road racing. Can easily support more than 1200hp. 



  • Gold-Zinc Coated Brackets with 4th diff mount option
  • Upgraded axles with lifetime warranty
  • Fully rebuilt Ford 8.8 pumpkin with carbon clutch LSD and aluminum diff bushings installed
  • 3.5" Aluminum driveshaft with billet trans adapter


This kit is fully bolt-on and does not require any permanent modifications. Works great on auto, manual and DCT cars. DCT cars must run a XHP flash to change gear ratio.
