F87 M2, F80 M3, F82 M4, F10 M5 axle shaft seal 33137596788

Exact-fit BMW differential output shaft seal for F87 M2, F80 M3, F82/F83 M4, F10 M5 and F12/F13 M6. Part number 33137596788 - the same seal BMW uses to stop gear oil leaks at the diff output.

Not a generic copy. Not a 'compatible' guess. This is the OEM-specified part, precision-machined for correct seating and long-term sealing - critical on fast-road or track-day cars where oil loss risks diff failure.

• Stops leaks at the driveshaft/diff interface - no more oily rear subframe or ruined diff mounts
• Fits without modification; replaces failed or worn factory seals during service or refresh
• Stocked and ready - no waiting for overseas shipments or 'will fit' uncertainty
