The “ultimate diff” – Zip’s severe duty unit with a Quaife torque biasing carrier added. Superior to a limited-slip, the Quaife unit drives both wheels equally under most all conditions, one exception being cornering. Here the biasing action directs near-total power (80/20) to the outside planted wheel. Less inside spin means harder-on-the-throttle response to build higher exit speed.

Proprietary to Zip’s Race Duty Quaife diff are fittings to allow use of a temperature sensor and differential cooler, plus micro-polished gear sets for reduced friction. Built in-house by skilled technicians, all differentials are backed by Zip’s satisfaction guarantee and include a 3-year unlimited mileage warranty against defects in materials or workmanship. Available in 3.73. 3.90 and 4.10 ratios. Differentials sold on exchange.
