Quaife Automatic Torque Biasing (ATB®) limited slip differential

The Quaife Automatic Torque Biasing (ATB®) limited slip differential is highly praised for its traction capabilities making it a top choice, for enhancing performance in vehicles with open differentials.

Regarded as the go to upgrade for car enthusiasts and professional racers looking to improve their vehicles grip, handling and braking abilities the Quaife ATB® limited slip differential can seamlessly replace factory differentials. It's compatible with a range of front wheel drive, rear wheel drive and all wheel drive vehicles.

Having been introduced in the 1980s Quaife ATB® limited slip differentials have established a solid reputation for their precision engineering and durability. These British made differentials are widely used in motorsport events like rallying, circuit racing, sprinting, rallycross, Time Attack competitions, as regular everyday driving, on public roads.

What it Does

Once installed, drivers will immediately feel the difference as the Quaife ATB® limited slip differential automatically adjusts the torque distribution across the axle to the wheel with the most traction. This significantly reduces unwanted wheelspin and slip, decreasing understeer in front or all-wheel-drive vehicles and minimizing oversteer in rear-wheel-drive cars. Rear-wheel-drive vehicles equipped with a Quaife ATB® limited slip differential become more manageable during oversteer situations, allowing drivers to fully utilize their car's capabilities, resulting in a more thrilling, rewarding, and faster driving experience.

In front-wheel-drive cars, the Quaife ATB® limited slip differential provides notable performance improvements during heavy braking. The differential’s inherent torque transfer properties reverse in this scenario, transferring torque away from the wheel that is locking up. This enhances braking efficiency, delays the activation of electronic ABS systems, and enables drivers to brake later and deeper compared to a standard open differential unit.

When these advantages are combined, it becomes clear that the Quaife ATB® differential offers a substantial performance enhancement over an open differential. Independent testing by Redline Magazine on a Renault Sport Clio 200 demonstrated that, even on a short circuit, lap times were reduced by over two seconds, proving the Quaife ATB® differential to be an exceptional value-for-money upgrade.

Superior Quality, Safe Performance, No Wear, Lifetime Warranty

The Quaife ATB® differential is fully compatible with manufacturer electronic traction control and anti-lock braking systems, providing numerous advantages in both performance and longevity over traditional plate-style LSD units.

Operating silently, even during low-speed maneuvers such as parking, the Quaife ATB® limited slip differential never 'locks.' This makes it progressive, safe, and user-friendly. Unlike plate-style LSDs, it does not have clutches, ramps, springs, or other components that require frequent replacement. The Quaife ATB®'s system of helical gears is highly durable and designed to work with standard transmission oils, ensuring a longer service life and less maintenance.

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 OEM's

The Quaife ATB® Differential has been selected by some of the world's most prestigious automakers for their high-performance models. Esteemed brands such as Ford, General Motors (GM), BMW, Lotus, and Chrysler have incorporated our renowned 'traction enhancer' into their vehicles. Notable models include all three generations of the Ford Focus RS, the Lotus Evora 400, the Mini JCW Challenge, and the Chevrolet Cobalt SS. The latest vehicle to showcase the ATB is the highly acclaimed 2018 Ford Fiesta ST hot hatch.

British Made Through and Through

All Quaife products are meticulously crafted from certified steel billets and rigorously inspected to meet ISO9001-2008 standards. ATB® Differentials are manufactured in the South East of England, specifically at Quaife's Gillingham facility in Kent. Utilizing state-of-the-art 3D CAD/CAM design software, robotic 3-, 4-, and 5-axis CNC machining centers, and tri-coordinate measuring machines, skilled personnel push the limits of mechanical precision engineering. As an ISO9001 registered company, Quaife prioritize quality control, employing specialist Quality Inspectors trained to use temperature-calibrated inspection equipment.
