Gearbox parts and LSDs

This section focuses on transmission parts for Porsche, including, but not limited to, limited slip differentials (LSD), gears, casings, shifters,and gearbox accessories.

Bisimoto sells and runs ATB Helical LSD differentials for Porsche, to replace the standard open differential. A direct replacement for the standard Porsche differential, the Helical LSD differential transforms your cars performance.

Unlike a conventional plate-style limited slip differential, the Porsche Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation, on the street, and track.
