Oem LSD Preload shim (belleville washer) set 168mm for BMW E30 E36 E34

Enhance Your BMW's LSD Performance with RacingDiffs Preload Shims

A frequent issue with ZF Limited Slip Differentials in BMW models such as the E30, E36, and E34 is the loosening or damage of preload shims (Belleville washers) due to overheating. To maintain optimal performance and reliability, it is essential to replace these shims during an LSD rebuild.
