Wavetrac ATB LSD differential BMW F10 550i / E90 335d – for ratios 2.35–2.81

The Wavetrac ATB LSD is a mechanical locking differential for BMW F and E-Series models with rear ratios between 2.35 and 2.81. The patented ATB design distributes engine torque efficiently to both rear wheels, improving traction during acceleration, cornering and on slippery surfaces.

Unlike traditional disc LSDs, Wavetrac does not require wearing friction plates or special additives. The lock operates automatically based on torque differences and maintains the lock even in situations where there is very little load on one wheel – for example on uneven tracks or slippery surfaces.
