Special tools, upgrades and spares


Why to choose RacingDiffs?

Besides LSD clutch plates, bearing kits, conversion sets and complete LSD units  we produce heavy-duty spare parts for BMW factory Limited slip differentials.

If you have a broken gear, a pin, LSD cap, damaged ramp or anything else which stops you from repairing your differential, you are on the right place. We make all parts which you can't purchase anywhere else, not wishing to sell a complete LSD unit, if you need only a pin or a single gear to repair yours. Instead of bare profit, we believe in trust. That is why we are making something that no one else does, BMW LSD spare parts.

Besides spare parts, you will find various accessories for differential adjustments, such as Backlash shims and C clips, gear ratio swap sets, crown gear spacers and much more.

There are also special tools which we use in our workshop, necessary for some builds, such as BMW E9X M3 diff rebuild.

If you have a need for parts we don't have already, please send email and we will get back to you with the solution.
