Technical Sealing for Cero Big Bore Dampers

The 3RACING Cero Big Bore Low Profile Absorber O Ring, M13 x 1.5, is specified to sit low in the shock stack for minimal interference with piston movement. It provides a reliable seal that supports consistent oil retention and damping repeatability under racing loads.

Performance and Service Considerations

For tuners and race technicians, a correctly sized, low profile O ring reduces seal displacement and contributes to predictable shock response. Inspect O rings during each rebuild cycle and replace when elastomer degradation is evident to maintain setup consistency.

Compatibility and Installation Notes

Designed for the Cero Big Bore family, the M13 x 1.5 geometry matches the intended shaft and cap interfaces. Apply a light coat of your damper oil to the O ring for smooth installation and check seating to avoid uneven compression that can cause leaks under high impact forces.

A low profile O ring minimises intrusion into the shock bore, lowering stiction and allowing the piston to follow its designed flow characteristics more closely. This helps preserve predictable damping through repeated cycles.
Check for surface cuts, hardening, and dimensional flattening. Measure critical M13 x 1.5 seating and replace the O ring if any deviation from nominal is found to avoid variable oil flow.
Use a thin film of the race viscosity shock oil to ease fitment, align the shaft concentrically, and torque caps evenly. Verify no pinching occurs and perform a quick bench cycle to confirm smooth operation before track use.
