TRAXXAS Revo Transmission Ring Gear Steel STRV1201 by GPM  [STRV1201]

Replacement ring gear for Revo transmissions

The STRV1201 ring gear is an aftermarket ring intended for TRAXXAS Revo and Revo3.3 platforms, supplied as one pcs. It is a hardened-steel alternative to stock gears and is aimed at hobbyists seeking improved wear life in the gearbox.

Placed in the gearbox, the ring gear forms the mating surface for the motor pinion and the spur gear train, offering a more wear-resistant interface than softer stock parts. It is for model drivetrain use only and carries no wider vehicle implications.

Fitting steps: remove the gearbox cover and old ring gear, confirm the STRV1201 seats flush and that the pinion-to-ring mesh is even, then reassemble and test free rotation. Inspect bearings and shaft alignment because correct clearance keeps noise down and operation smooth.

Tuning benefit: a hard-steel ring gear helps the drivetrain keep consistent tooth geometry under repeated changes, which is helpful for frequent ratio swaps or higher RPM motor setups.
