Choosing the Correct OS Giken Product

Match the exact manufacturer part number first. Year, make, and model alone do not confirm a drivetrain component because chassis, engine, transmission, differential housing, axle or input spline, final drive, clutch series, and release system can vary within the same model.

Frequently Asked Questions

How do I confirm an OS Giken drivetrain part fits my vehicle?
Match the exact manufacturer part number and year, make, and model, then verify chassis, engine, transmission, differential housing, spline, final drive, clutch, and release-system notes.

Do OS Giken differentials and clutches require professional installation?
Yes. These parts require precise measurements, approved lubricants, specified torque values, correct release geometry, proper setup, and the current break-in and inspection procedure.

Is OS-250R V2 gear oil approved for every transmission or differential?
No. Use it only where the stated 80W-250 viscosity and OS Giken friction requirements are approved, and follow the component's fill quantity, level-setting, and service instructions.
