Wavetrac Torsen Limited Slip Differential BMW 215K Axle

Wavetrac Torsen Limited Slip Differential BMW 215K Axle


Item #: WT-30.309.170WK


The Wavetrac differential is a newcomer to the market, but offers advantages compared to standard torsen differentials like Quaife or Peloquin's. Those differentials are non preloaded torsen units, so if either wheel has zero traction, the differential will not function and you will spin the wheel with no traction. The wavetrac differential overcomes this by adding preload to the torsen setup via a patent pending design. These differentials are high quality, designed and manufactured in USA and come backed with a lifetime warranty. In addition, wavetrac is committed to actually keeping them in stock, so supply is not an issue like it may be with other brands.

Replaces the entire OEM differential assembly with a high quality torsen limited slip
