Limited Slip Differential M56 Gearbox

Quaife ATB Helical LSD differential for  all Volvo's with the M56 gearbox. A direct replacement for the standard Volvo open differential, the Quaife ATB Helical LSD differential transforms your car's performance. Unlike a conventional plate-style limited slip differential, it relies on gears rather than clutch plates for its operation. That means it is much smoother in operation. It never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. But it automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.
