RacingDiffs Limited Slip Differential Reinforced Billet steel cap 188mm (2.65 - 3.07) for BMW

ZF Limited Slip Differential often found in BMW E30, E36, E34, Z3... has cast iron parts that often fail under increased load/power due to fatigue. When you upgrade your LSD and change the ramp angle to 30°/30° or 30°/60°, there is an increased risk of the differential cap breaking.

For this issue, a RacingDiffs reinforced billet steel cap is a permanent solution. By installing this product, you will avoid a cap failure for good.
The cap is made from the highest quality tool steel, hardened and nitrated for the ultimate resistance and longevity.
Reinforced bolts are included in the set as well, which do not suffer from the internal stripping problem as compared to the original bolts.

The cap is highly recommended for drifting and any type of racing.

*Please note that the 188mm cap is made to fit with a 4 clutch pack. It is 4mm shorter than the original, so a minimum number of clutch plates is 3.
