Wavetrac is the most technologically advanced ATB LSD available on the market, with the patent-protected features its design delivers performance and longevity like no other.

Find out why Wavetrac’s ATB LSD is unrivalled by clicking the link here.

Most BMW axles from 07 onwards were manufactured with a friction welded ring gear and open differential. This can cause some headaches for installation concerning vehicle downtime while the factory differential/ring gear is separated by precisely machining the parts away.

Wavetrac has now solved this for the M135i equipped with the 33107599411 3.08 axle.

Please provide your VIN and transmission type at the checkout during ordering or prior to member of staff by email or phone so we can verify which axle and ratio are correct for you so we supply the correct axle.

Each built differential comes complete with the following:

  1. Wavetrac ATB LSD
  2. OE BMW ring gear bolts
  3. New, Genuine BMW Axle Seals
  4. Backlash Setup to OE Tolerances
  5. Precisely Machined Ring Gear

You will need to spec oil, for this application we advise for Motul Competiton 75w140.

JXL Performance offer these as an outright purchase. There is the option of an exchange differential with the manufacture which can save you £400, please contact us for details.
