Originally introduced in the 1980’s, 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.Key FeaturesSafe, progressive and seamless in action, the Quaife ATB differential never ‘locks’Controlled power is transmitted to all driven wheels, to maximise traction and minimise wheelspin, particularly in slippery conditionsFitment greatly reduces unwanted torque steer, understeer or oversteerDesigned to work in harmony with road car electronic stability and traction control programsImproves braking performance on front wheel drive cars by reducing lock up and minimising ABS intrusion due to torque transfer actionReduces tyre wear, especially on front wheel drive carsGear operated with no service components to replace – everDirect replacement for factory standard ‘open’ differential unitRetains normal axle lubrication systems and maintenance scheduleOver 100,000 units sold worldwide since the 1980’sAvailable for over 400 different applicationsBacked by a Quaife lifetime warranty for both motorsport and road useWhat It DoesOnce 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 differential’s 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 it’s 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 WarrantyFully 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 ATB’s well-proven system of helical gears is extremely durable, plus it’s 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 OEMsThe Quaife ATB Differential has been used by some of the world’s 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’.
