Quaife Helical LSD's - How They Work
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
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 the 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
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
The Benefits Are:
- Safe, 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 conditions
- Fitment greatly reduces unwanted torque steer, understeer or oversteer
- Designed to work in harmony with road car electronic stability and traction control programs
- Improves braking performance on front-wheel drive cars by reducing lock-up and minimising ABS intrusion due to torque transfer action
- Reduces tyre wear, especially on front-wheel drive cars
- Gear operated with no service components to replace – ever
- Direct replacement for factory standard ‘open’ differential unit
- Retains normal axle lubrication systems and maintenance schedule
- Over 100,000 units sold worldwide since the 1980’s
- Available for over 400 different applications
- Backed by a Quaife lifetime warranty for both motorsport and road use
