Precision Sealing for Cactus 2WD Dampers

The 3Racing CAC-144 O-ring set is produced to maintain seal integrity and damping repeatability on Cactus 2WD shock assemblies. These O-rings are dimensioned for consistent contact with the piston shaft, helping to avoid progressive oil loss that affects tuning accuracy. Durable material selection reduces the rate of seal deformation under repeated use.

Consistent Damping for Setup Work

For competitive tuning, predictable damper behaviour is essential. Replacing worn CAC-144 O-rings restores leak-free operation so setup changes yield repeatable results on compression and rebound settings.

Fitment and Service Notes

Designed for direct fitment to Cactus 2WD dampers, the CAC-144 seals are straightforward to install during routine service. Inspect seal condition during each rebuild and replace to maintain optimal shock performance and minimise variance between runs.

How do CAC-144 O-rings affect tuning consistency?

Correct seals prevent oil migration and pressure loss, preserving the intended damping curve so setup adjustments produce consistent lap to lap behaviour.

When should I replace these seals during a race program?

Check seals at each major service interval and after any sign of oil seepage; proactive replacement avoids unexpected damping changes during events.

Any assembly best practices?

Apply a thin film of shock oil or compatible grease to the seal before sliding onto the shaft, and avoid twisting to prevent nicking the sealing surface.
