QUAIFE ATB LIMITED SLIP DIFFERENTIAL

Often imitated but never improved, the Quaife Automatic Torque Biasing (ATB) limited slip differential is the perfect traction solution that delivers noticeable performance benefits on any car using a factory open differential unit.

Widely accepted as the upgrade of choice for road car owners and motorsport competitors looking to improve their vehicles traction, handling balance and braking capabilities, the Quaife ATB limited slip differential is a direct replacement for a standard factory open differential and is available for most popular front, rear and four-wheel-drive cars.

Originally introduced in the 1980s, Quaife ATB limited slip differentials are well proven, precision engineered, British made, highly durable and used worldwide in rallying, circuit racing, sprinting, rallycross and Time Attack, as well as the open road.

What It Does

Once installed, drivers will notice an immediate difference, as the Quaife (ATB) limited slip differential automatically biases the torque across the axle to the wheel with the most grip. Unwanted wheelspin and slip are greatly reduced, resulting in less understeer on front or four wheel drive machines and reduced oversteer on rear wheel drive vehicles. Rear wheel drive cars with a Quaife limited slip differential become more controllable during oversteer moments, enabling drivers to exploit the full potential of their machines for the first time, leading to a more exciting, rewarding and rapid driving experience.

On front wheel drive cars the Quaife ATB limited slip differential also delivers significant performance benefits during heavy braking. In this situation the Quaife differentials inherent torque transfer characteristics work in reverse to transfer torque away from the locking wheel. This enhances deceleration, delaying the intrusion of electronic ABS systems and allowing drivers to brake later and deeper with the Quaife ATB limited slip differential than is possible with a standard open differential unit.

Add these benefits together and its hardly surprising that in outright performance terms the Quaife ATB differential can make a remarkable difference compared to an open differential. Back to back independent testing by Redline Magazine on a RenaultSport Clio 200 has proven that even on a short circuit lap times are reduced by over 2 seconds, making the Quaife ATB differential an excellent value for money upgrade.

Superior Quality, Safe Performance, No Wear,Lifetime Warranty

Fully compatible with manufacturer electronic traction control and anti-lock braking systems, the Quaife ATB differential offers a number of key advantages in both functionality and service life compared to conventional plate-style LSD units.

Silent in operation (even during low-speed parking manoeuvres) the Quaife ATB limited slip unit never locks, making it progressive, safe and user friendly. Unlike plate-style LSD designs there are no clutches, ramps, springs or other wear prone components to replace at regular intervals, because the Quaife ATBs well-proven system of helical gears is extremely durable, plus its designed to use standard transmission oils.

This makes the Quaife ATB limited slip differential a genuine fit and forget upgrade that offers compromise-free performance and unbeatable reliability on the street, strip, stage or circuit,backed by a lifetime warranty.

Trusted By OEMs

The Quaife ATB Differential has been used by some of the worlds most revered motor manufacturers in their high performance model lines. Ford, General Motors (GM), BMW, Lotus and Chrysler are just some of those who have chosen our signature traction enhancer.
