The Automatic Torque Biasing Helical LSD differential is Quaife's unique design, and is an after-market differential that provides smooth, constant traction for racing or slippery road conditions.

Suitable as an ideal replacement for any front, rear or four wheel drive application, this ATB Helical LSD differential has the added benefit of no adverse effect on the steering of a front wheel drive vehicle.

Quaife ATB Helical LSD differentials have been used in a wide array of applications, from Formula 1 cars to emergency and public utility vehicles, where all weather mobility is essential, and where the product must perform in the most demanding of conditions.

Available to suit a very wide range of vehicle applications, from Alfa Romeo to Volkswagen and including Ford, BMW, Honda, MG & Rover, Vauxhall/Opel, as well as a range of light commercial vehicles.

The characteristics of the differential are that it progressively locks as torque increases; there are no plates or clutches to wear out, unlike the more conventional limited-slip designs. The ATB Helical LSD differential is particularly effective in combating the effects of FWD torque steer and understeer.

As well as offering to overhaul your differential (front,rear or four wheel drive) we offer for some applications an option to have your standard limited differential uprated allowing more power and performance, this is a process that consists of fully stripping & degreasing the old unit, new internal plates added for better resistance and fully speed tested for the correct tolerance
