Wavetrac Rear Differential BMW M3 (E46/E92) M5 (E60) M6 (E63)

Wavetrac Rear Differential - BMW M3 (E46/E92) M5 (E60) M6 (E63)

When traction matters most, a standard open differential simply can't keep up. The Wavetrac Differential is engineered from the ground up by Autotech Driveline in the USA, bringing genuine helical gear technology and patented torque biasing to your BMW. What sets Wavetrac apart is its cam device that maintains drive to the gripping wheel even under zero axle load — a condition where most helical diffs fall apart and behave like an open unit.

This listing covers the Wavetrac rear differential designed to suit the BMW M3 E46, BMW M3 E92, BMW M5 E60, and BMW M6 E63. This unit uses OEM drive flanges, retaining your factory hardware.
