Wavetrac BMW 215K LSD Wavetrac Helical BMW 215K LSD Wavetrac Helical

A unique helical LSD for late model BMWs. A supurb option for your M135i MT, M235i MT, E39 540i or E9x 335i. This is a quiet, predictable and long-lasting LSD unit. Backed by a strong warranty which is transferrable should you sell the vehicle. The Wavetrac is the only helical design which will not spin the inside wheel should it lift off the road/track. The Wavetrac differs from a traditional helical, and has friction plates fitted which are replaceable and can be changed to modify the lockup characteristics.

  • Innovative: Patented Wavetrac® design automatically improves grip in low traction conditions. This feature is truly innovative and unlike any other torque biasing diff design.
  • Superior Materials: 9310 steel gears run in case-hardened billet or forged steel bodies. ARP® fasteners used throughout.
  • Maintenance Free: As supplied new, the Wavetrac® differential will perform a lifetime of service without maintenance or rebuilds.
  • Customizable: If desired, you can alter the diff’s behavior to suit your needs using optional components.
  • Limited LIFETIME Warranty: All Wavetrac® differentials include a transferable, Limited Lifetime Warranty.
A Wavetrac LSD is a great choice for your BMW whether it is for road or track. Don't forget your 215K LSD install kit.
