Competition grade outer joint for Cactus 2WD

The 3Racing CAC-137A universal shaft outer joint is engineered with a focus on reduced slop and consistent engagement for Kyosho Cactus 2WD drivetrains. Its design supports tighter tolerances to help maintain alignment under track loads.

Precision engineering and fit

Developed for competitive use, this outer joint complements tuned drivetrains by providing a repeatable connection point that minimises axial and lateral movement. Fitment aligns with factory Cactus 2WD geometry for straightforward installation.

Setup considerations for racers

When paired with balanced drive components and correct alignment, the 3Racing CAC-137A can improve throttle feedback and reduce unpredictable driveline behaviour. Regular inspection for wear and correct assembly torque are recommended to preserve performance.

What should I check during installation?

Ensure the joint seats squarely and that mating shafts are free of burrs. Confirm alignment and smooth articulation before finalising hardware torque to avoid binding.

How does this joint affect tuning options?

A more predictable joint reduces drivetrain variability, allowing finer suspension and throttle mapping adjustments without masking driveline inconsistencies.

Maintenance advice for competitive use

Inspect the joint after heavy events, keep the articulation area clear of debris, and replace any component showing measurable play to retain peak performance.
