3Racing CAC-310 27T Mid-Motor Aluminium Idler Gear - Precision Upgrade  [CAC-310]

Precision aluminium idler for Cactus 2WD

The 3Racing CAC-310 is a 27T aluminium idler designed for mid-motor installations. Precision finishing and the tooth profile ensure steady engagement and help reduce slop in demanding racing conditions.

Enhanced durability under load

Aluminium brings better resistance to wear than plastic idlers, keeping the drivetrain tighter for longer. The 27 teeth maintain consistent contact with mating gears and reduce the frequency of part replacement.

Specifically built for mid-motor fitment

Engineered for use in the Cactus 2WD mid-motor layout, this idler fits cleanly into the stock geometry and supports reliable drivetrain alignment. It is suitable for those aiming for consistent lap times and fewer mechanical issues.
