Limited Slip Differential M66 Gearbox

Quaife ATB Helical LSD differential for all Volvo's with the M66 6-speed 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.
