Traxxas Idler 20-Tooth & Idler Shaft RC Gear - 3996X

The Traxxas TRX3996X Idler Gear 20-Tooth and Idler Gear Shaft is a genuine Traxxas spare part designed to restore correct drivetrain function in compatible Traxxas RC models. The idler gear sits between the motor pinion and the main transmission gear, transferring drive smoothly through the gearbox — when it wears or strips, replacing it with the correct 20-tooth specification is essential to getting your vehicle running again. Using a genuine Traxxas part ensures the tooth count, shaft diameter, and material match the original factory specification.
