Installing a new LSD or changing the gear ratio on your post-1999 BMW? Correct carrier preload and backlash are critical for quiet operation and long life. The RacingDiffs Precision C-Clip Kit gives you the fine adjustment range needed for a factory-grade setup.
| Intended use | Carrier preload and backlash adjustment on post-1999 BMW differentials (non-M). |
| Kit content | Precision C-clips (~3.0–4.0 mm range in 0.1 mm steps), 10 pieces total. |
| When to use | After installing an LSD carrier or changing final drive ratio; whenever backlash/preload must be reset. |
| Measurement | Use a dial indicator at the ring gear to set backlash to BMW specification; verify tooth contact with marking compound. |
| Best practices | Work clean; record each trial stack; torque fasteners to spec; rotate and re-measure after seating bearings. |
Note: Backlash/preload targets vary by differential family; follow BMW service specifications for your chassis.
