This listing is for a E60 M5/E63 M6 differential rebuilt to stock specs by the experts at Diffsonline. No charts and data to ponder - if you just want your differential to perform as it did when new - or better! - this is your best option. Note that the current list price on a rebuilt diff from BMW is $4,550. And ours is better.

This listing takes out all of the guesswork and research on buying a E60 M5/M6 diff. The Diffsonline E60 M5 diff is rebuilt with the original gear ratio (3.62) and with a slightly improved M Variable limited-slip unit. Our rebuilt M Variable units are quieter and last longer than the original factory builds. Polishing of gears and bearings is also available to improve service life and performance.

The rebuild process is extensive:
  • The used diff is disassembled and cleaned
  • The outside case (carrier) is stripped of grease, grime, and rust
  • The M Variable limited slip unit is prepped and serviced
  • The gear set is assembled with the LSD
  • Any machining of the carrier is done in-house
  • New OEM bearings are fitted
  • New OEM seals are fitted
  • The entire internal assembly is aligned (crucial in avoiding gear whine later on)
  • Final assembly and checks
  • Carrier is given a fresh coat of black paint
  • Shipment to your door in special heavy-duty packaging
A $500 core charge is not included in the the price and will be added during processing. We need your original diff returned so we can continue rebuilding diffs for other customers. Your original differential must be returned to Diffsonline within 14 business days. Only complete and reusable cores will be eligible for a refund (no blown out, abused, or modified cores please). You must return a diff equal in components and accessories to the one sent to you. You can avoid the core charge altogether by sending in your original diff to be rebuilt.

The diff you receive will be ready to install, minus the fluid and rear cover (which you remove from your original diff). We recommend the factory Castrol SAF-XJ fluid. Break-in instructions are included.

  • I’ve never dealt with a true “race” shop like BW and I really have enjoyed the experience. I always feel like I’m getting the best advice, and suggestions for true race car set up. Your technical expertise on even the minute details of building race cars is really impressive, and some I value greatly...
