About OS Giken UK

OS Giken UK is the UK web shop for OS Giken clutches, limited slip differentials and close-ratio gear sets. It is run by TORQEN Ltd, an independent distributor of OS Giken parts, not a branch of OS Giken Japan.

Most of what you see here is made to order by OS Giken in Japan and usually takes 2 to 3 weeks. Prices are in pounds, and every listing shows the chassis and engine it fits, so you can check your car before you order.

Not sure which clutch or LSD suits your car and your power? Send us the chassis code, engine and what you use the car for, and we will check fitment with you before you order. Contact us here.
