Dodge LSDs

OS Giken limited slip differentials for Dodge, covering the Viper. Types listed here include Super Lock, with SPEC-S 1.5-way and SPEC-X 1.1, 1.5 or 2-way versions where OS Giken makes them.

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.
