Are you bringing your differential back to life and want to upgrade at the same time? Our three clutch limited slip differential kit will do the trick! This is our most popular setup. Dynamic lockup is increased and clutch durability is significantly improved over that of a stock unit allowing you to extract more rear wheel traction.

Stock drivability is maintained by properly tolerancing the components to avoid excessive preload!

With this purchase, you'll receive three 188mm clutch discs, three properly toleranced 188mm 4-lug dog ear plates and eight 12.9 grade carrier bolts. Everything that you need to upgrade your differential!

Best of all, this kit does not require any machine work on standard 188mm differentials.

Our clutches are coated with a molybdenum traction surface and are specifically designed for the high temperature abuse situations that occur within the BMW differential. The clutches will retain the smooth limited slip engagement feel of the stock differential while providing long term durability. Our dog ear plates are precisely machined and hardened to ensure long term use.
