Quaife ATB Limited Slip Differentials at JXL Performance

When pushing a high horsepower front wheel drive or rear wheel drive car hard out of a tight corner, open factory differentials suffer from a massive mechanical flaw. Instead of sending power where it is needed, an open diff simply spins the inside wheel with the least traction, destroying your acceleration and handling balance. As the undisputed global gold standard in mechanical differential technology, Quaife manufactures legendary Automatic Torque Biasing (ATB) limited slip differentials designed to completely eliminate wheel spin, maximize cornering grip, and radically improve traction under hard acceleration.

Helical Gear Design and Maintenance Free Reliability

Unlike traditional clutch type limited slip differentials that rely on friction plates prone to wearing out and requiring constant servicing, the Quaife ATB differential operates entirely through a sophisticated arrangement of helical gears. There are no clutch packs to burn out, no special friction additives required in your gear oil, and zero aggressive locking chatter during low speed parking maneuvers.

Under normal driving conditions, the Quaife diff acts just like a standard open differential for smooth road manners. However, the exact moment one wheel begins to lose traction and spin faster than the other, the helical gears instantly and smoothly redirect torque to the wheel with the most grip. This progressive power transfer happens seamlessly without abrupt engagement, giving you absolute confidence whether powering through a soaking wet roundabout or driving at the limit on a dry circuit.

Traction Dominance for BMW M Lite, Ford ST/RS, and Mini

Quaife differentials are an absolute mandatory upgrade for unlocking the true potential of modern performance platforms. In the BMW M Lite community, installing a Quaife ATB diff is the single best handling modification you can make to tame the massive low end torque on models like the F22 M140i and M240i, ensuring power is laid down evenly to both rear wheels instead of lighting up a single tire.

They are equally legendary in the hot hatch and fast Ford scene. For front wheel drive platforms like the Mk7 and Mk8 Ford Fiesta ST, Focus ST, RenaultSport Clio and Megane, and the supercharged Mini Cooper S and JCW, a Quaife differential completely eliminates aggressive torque steer and pulls the front end hard into the apex.

JXL Performance supplies genuine Quaife ATB limited slip differentials to driving enthusiasts worldwide. Please check individual product listings for accurate availability, as lead times can vary depending on specific gearbox codes, final drive ratios, or specialized motorsport applications.
