Most limited slip diffs feature pre-load which saps power from the engine, makes corner turn-in difficult and results in torque steer. The ATB eliminates all of these features by working like an open diff until a wheel starts to lose grip. When one wheel starts to slip, the ATB sends torque to the wheel with more grip and keeps you accelerating. Quaife are so confident of their quality that they offer a lifetime guarantee with the ATB.* *We ensure the lifetime guarantee if you buy your ATB on our website
