BMW E46 (M3) Upgraded Front Differential Bolt

Sale price$15.00 USD


This is for the BMW E46 M3 only! This bolt is 70mm long. Please compare to your OEM bolt before ordering.

This is a very common upgrade done by those that track or drift their car. The stock bolt is weak, and, when exposed to aggressive driving, is known to snap in two. 

We only recommend this upgrade to those that have already or are going to upgrade or replace their factory diff bushing. A sloppy front diff bushing is the main reason these bolts tend to snap!

Class 10.9 steel is at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer.

  • Black-Oxide
  • Class 10.9 Steel
  • Flanged Hex Head
  • Black corrosion-resistant-coated steel is more corrosion resistant in wet environments than zinc-plated steel 
  • Screws meet ISO 898-1 and comply with specifications and testing requirements for material quality.

Kit Includes: 

(x1) Grade 10.9 M14 Bolt
