Race focused front damper shaft for Cactus 2WD by 3Racing CAC-139B

The 3Racing CAC-139B front damper shaft is produced to support precise tuning of damping characteristics on the Cactus 2WD. It helps deliver repeatable shock behaviour so setup changes have predictable results during race sessions.

Setup driven design for tuning consistency

Intended for competitive use, the shaft reduces lateral play in the damper stack and promotes stable piston movement. That steadiness aids suspension setup work and improves the correlation between shim, oil and spring choices.

Compatibility for straightforward fitting

Matched to the Cactus 2WD front dampers, this shaft installs into the original shock components without complex modification. The part supports common tuning workflows and helps racers extract consistent handling across multiple runs.

By stabilising damper movement, it provides clearer feedback when adjusting oil weight, spring rate or piston configuration, making setup iterations more effective.
Yes, the part is intended to support track tuning where repeatability and predictable damping are required to compare changes accurately.
The shaft is compatible with standard Cactus 2WD shock internals, allowing you to test various oils and piston setups while benefiting from reduced internal play.
