Quaife Differentials

A global leader in the performance automotive drivetrain industry since 1965, Quaife is widely known for producing one of the best limited slip differentials on the market. Quaife is headquartered in southeast England, but mountune USA is proud to be an official seller of products from Quaife in the USA.

The Quaife (sometimes seen as Quaiffe) differential works by biasing “the torque across the axle to the wheel with the most grip,” resulting in reduced wheelspin and slip and subsequently less understeer on front/four-wheel drive or oversteer on rear-wheel drives.

Quaife’s limited slip differential is different from most due to its unique design, which is said to have revolutionized the performance differential market. This system of helical gears is not only highly durable but is also free from items that require regular replacements, like clutches, ramps and springs. This, combined with the fact that the Quaife ATB limited slip differential never locks, means it’s safe to say that this unit is one of the safest and most progressive on the market.

The Quaife ATB differential is one of the best upgrades you can add to your Ford. Improved traction and cornering provide a better driving experience on both the street and the track. All Quaife ATB differentials for Ford include a lifetime warranty.
