Jaguar Limited Slip Differential Complete Unit for XK 4.2

As a direct replacement for the standard factory “open” differential, The ATB Helical LSD unit can transform the performance of your car. Unlike a conventional plate-style limited slip unit, the unit relies on gears, rather than clutch plates for its operation.

This means it is much smoother in operation, because, unlike a conventional plate-style LSD, it never locks harshly when a set pre-load of wheel slip is experienced across the driven axle. Instead, it automatically biases the torque away from the spinning wheel to the other driving wheel on the same axle – to a constantly varying degree and it never locks.

The result is superior, controllable traction without “twitchiness” or “snatch”.

Please note, this item and price is for an exchange unit, Paramount will require your old differential unit in exchange. If you would rather not exchange your diff unit, there will be an additional surcharged of £400. Either option is fine. Please let us know if you need any help or advice
