Wavetrac Helical LSD Differential BMW 335i (E9X) / 540i (E39) / Z8 (E52) 215K Axle R=2.81+

Wavetrac Differential, BMW Early E9X 335i All E39 540i (215K Axle w/ Bolt On Ring Gear) R=2.81+

The Wavetrac differential is the only torque-biasing differential on the market with patented cam technology that keeps drive going to the gripping wheel even under zero axle load conditions — the scenario where a conventional limited-slip or open differential simply gives up. Designed and manufactured by AutoTech Driveline, every Wavetrac unit is built from 9310 alloy steel gears housed in a case-hardened steel body, secured with ARP fasteners for lasting reliability on the street or track.

This listing covers the Wavetrac differential for the BMW 215K axle with a bolted ring gear and ratio of R=2.81 and above. Compatible vehicles include the E9X 335i (manual and automatic transmission, built before 03/2007) as well as all E39 540i and E52 Z8 models.
