Precision Seal Upgrade for Racing Dampers

The 3RACING Cero Big Bore Low Profile Absorber O Ring M12.5 x 1.5 is intended as a direct replacement seal for competitive Cero dampers. It provides a compact sealing surface that supports consistent oil retention and repeatable damper response.

Application and Fitment

Engineered to match the M12.5 x 1.5 interface on Cero big bore shock assemblies, this O ring aids in preventing oil migration that can affect lap-to-lap consistency. Confirm groove geometry before fitting when using aftermarket shock bodies.

Setup and Service Notes

For race setups, inspect and replace O rings during damper rebuilds to preserve tuning accuracy. Proper seating and light lubrication during installation reduce the risk of seal roll and ensure reliability under repeated compression cycles.

Is this O ring suitable for high frequency compressions on track?

Yes, when installed correctly the O ring maintains oil retention under repeated cycles, but inspect for wear more often in high frequency applications.

Any fitment cautions with converted shock bodies?

Aftermarket or converted bodies may have different groove profiles; verify the seating surface and clearances before committing to a race setup.

Do I need different seals for different oil weights?

The seal size stays the same across oil grades; however, heavier oils can increase damping and should be considered when tuning rather than changing seal dimensions.
