Quaife Diffs

Pro-Race Engineering supplies the full Quaife Engineering range of differentials — the British-engineered automatic torque biasing (ATB) helical differentials that have become the default choice for fast-road and trackday cars where smooth, progressive lock-up matters. Direct-fit ATB units stocked for VAG 02M / 02Q Syncro, Honda K-series, Honda B-series, BMW M-series rear diffs and many more platforms.

Quaife ATBs work well on cars that still see daily duties — no plate noise, no maintenance, no extra harshness over an open diff. For track-only or motorsport builds where higher lock-up percentages help, we also stock 3J Driveline NXG and Gripper plate diffs.
