Our upgraded E46 M3 Differential Front Mount Bolt is a replacement for the OEM Part # 33177840535.
The common issues with the E46 M3 differential bolt include;
- Zinc-flake finish has started to corrode
- Years of driving has worn the rubber bushing and now the bolt is allowing the differential to clunk (no longer tight enough)
- After removing the bolt to take out the differential, the threads in he bolt (or worse, the differential) are damaged
Improvements to our bolt include;
- Grade 12.9 (vs. OEM Grade 10.9)
- Yellow zinc (vs. OEM zinc-flake)
- Washer included is also yellow zinc plated
Each bolt has threaded verified and checked before shipping.
