3RACING SAK-C150G Cero Low Profile Big Bore Shock Seal O Ring  [SAK-C150G]

Service-Grade O Ring for Cero Dampers

The 3RACING Cero Big Bore Low Profile Absorber O Ring M12.5 x 1.5 is a compact replacement part aimed at hobbyists who maintain their own dampers. Its profile is made to sit neatly in Cero shock assemblies and help retain fluid.

Compatibility Notes

Use this O ring in Cero series big bore shocks where an M12.5 x 1.5 seal is required. It helps prevent oil seepage that can blunt damper action and affect handling.

Workshop Tips

When servicing, clean the mating surfaces and test the seal under low pressure before a full run. A correctly seated O ring makes rebuilds quicker and reduces follow-up tweaks.
