Collection: OS Giken limited slip differentials

OS Giken limited slip differentials: the Super Lock plate LSD, the TCD with its oil-cooling discs, and the Dual Core. Most are offered as SPEC-S (1.5-way) and SPEC-X (1.1, 1.5 or 2-way) versions. Use the make collections to find yours.

Each listing names the chassis and engine it fits. Check yours against the fitment table, or send us your car's details and we'll confirm before you order. Most parts are made to order by OS Giken in Japan and usually take 2 to 3 weeks.

OS Giken UK is run by TORQEN Ltd, an independent OS Giken distributor, not a branch of OS Giken Japan.
