Wavetrac Limited Slip Differential for BMW Diesel Models - E38, E39, E46, E60, E90, F21, F32
Transform traction, grip and on-throttle control with the Wavetrac limited slip differential for BMW diesel models. If you are looking for a BMW LSD upgrade for 125d, 325d, 330d, 430d, 525d, 530d, 535d and 740d, this bolt-in Wavetrac ATB gear type differential delivers faster corner exit, improved stability and consistent power delivery on road and track. Ideal for spirited driving, track days and fast road BMW builds.
Wavetrac is the only gear type ATB differential that maintains drive when one axle is unloaded. Where conventional helical gear diffs and torque biasing diffs can momentarily stop driving the loaded wheel when the inside wheel lifts or goes light over kerbs, wet surfaces or uneven tarmac, Wavetrac’s patented internal cam device creates load inside the diff so you keep putting power down. The result is predictable handling, smooth torque transfer and faster lap times.
We have fitted Wavetrac LSDs to customer BMW diesels and the feedback is consistently excellent. Owners report noticeably better traction in the wet, stronger acceleration out of tight bends and improved confidence when pushing on. If you want a BMW differential upgrade that works in all conditions without the harshness or maintenance of a clutch pack LSD, Wavetrac is the answer.

How Wavetrac improves your BMW
Corner harder and accelerate earlier. The Wavetrac LSD actively manages torque when the inside tyre unloads, keeping the outside tyre driving so you carry speed and stay stable. On wet roads, uneven surfaces and over kerbs, it keeps you moving forward. On road it feels smooth and unobtrusive. On track it is the diff you can trust when you are right at the limit. Smooth is fast.
