Lightweight aluminium idler for Cactus 2WD

The 3Racing CAC-310 idler gear is a 27T aluminium component built for mid-motor configurations. Its lighter mass and robust construction make it a sensible upgrade for drivers looking to fine tune drive feel without adding unnecessary weight.

Durable material for repeated runs

Aluminium construction reduces deformation and resists the quick wear that can affect plastic idlers. The 27 tooth design preserves correct gear ratio behaviour and reduces the chance of stripped teeth during heavy use.

Made to suit mid-motor geometry

Tailored to the Cactus 2WD mid-motor setup, the CAC-310 installs cleanly into existing layouts and helps maintain drivetrain alignment. It is a practical choice for hobbyists focused on reliable lap-to-lap consistency.

Can I use this with different pinion sizes?

Yes, the idler works with common pinion and spur combinations used on Cactus 2WD mid-motor setups. Check mesh and clearance when changing pinion sizes.

Will the weight change affect handling?

Switching to aluminium slightly alters rotating mass, which can sharpen throttle response. The change is subtle but can be felt by drivers focusing on traction and acceleration.

Do I need special tools to fit it?

Only basic hand tools are required. Use the correct driver for mounting screws, verify alignment, and torque fasteners to avoid damage to threads.

How often should I replace the idler?

Inspect the idler after intense race weekends. Replace if you spot significant tooth wear or deformation; aluminium lasts longer than plastic but is not indestructible.
