Idler Gear

The Idler Gear from CVR Performance is a precision-engineered steel component designed for use in CVR Protorque starter systems. This compact, lightweight gear serves as a critical load-transfer element in the starter's internal drive mechanism, ensuring smooth power transmission from the motor to the engine's flywheel. Built for reliability in demanding automotive applications, the Idler Gear is an essential replacement or upgrade part for technicians and enthusiasts maintaining high-performance starter assemblies.

Manufactured from durable steel in a natural finish, this idler gear maintains tight tolerances to minimize backlash and wear within the starter's planetary gearing system. Its compact dimensions (3.45 x 0.5 x 4.55 inches) allow for seamless integration into existing Protorque starter housings without modification. The minimal weight of 0.14 lbs reflects its efficient design—reducing inertial mass while maintaining the structural integrity needed to handle repeated cranking cycles and the torque loads typical of engine startup.

This replacement idler gear is ideal for anyone rebuilding or servicing CVR Protorque starter units in street, strip, or marine applications. Installation requires removal of the starter assembly and disassembly to access the internal gear train; proper alignment and seating of the gear are critical to starter longevity. Whether you're restoring a vintage muscle car starter or maintaining a high-output custom engine, sourcing an OEM-quality replacement ensures the starter delivers consistent cranking torque and reliability across cold starts and repeated use.
