BMW OE Final Drive Pinion Seal Guard - Small | Part No. 33121213903

Protect the heart of your BMW's rear axle assembly with this BMW original pinion seal guard in the small size, part number 33121213903. This factory component shields the input pinion area from grit, water and road spray to help reduce premature wear of the pinion lip seal and keep your final drive running quietly and leak free.

Built to BMW's exacting standards, this direct-fit cover plate installs like-for-like on the pinion flange area and is the smart preventative maintenance step to pair with a seal service or propshaft work. We fit this part on our own builds and customers' cars and the feedback is consistently excellent for longevity and fitment.

Reasons to choose this OE pinion protector

  • Genuine BMW component for precise fit and OE-level reliability
  • Shields the input flange and pinion seal from dirt, salt, moisture and debris
  • Helps minimise diff weeping and protects against premature seal failure
  • Cost-effective preventative maintenance during driveshaft or seal replacement
  • Proven in our workshop and by happy customers
