OS Giken release bearings, conversion kits and tools

Release sleeves, release bearings, pull-to-push conversion kits (movement alteration kits) and fitting tools for OS Giken clutches. Many clutch kits need one of these, and each clutch listing names the part it needs.

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.
