This planetary ring gear is supplied as a precision aftermarket spare for the TRAXXAS Unlimited Desert Racer 1/7 platform. Machined from 40Cr carbon steel and finished with a supplier-specified hardening black surface, the component is intended to increase surface wear resistance when compared to the original part. It installs into the planetary carrier as a single replacement gear for the listed TRAXXAS chassis.
Installation requires gearbox disassembly and removal of the planetary carrier to exchange the ring gear. During service, inspect bearing fits and carrier surfaces, confirm gear mesh and axial runout, and verify clearances; correct alignment and bearing support are critical for consistent transmission load distribution and long-term durability. The product is supplied as the single ring gear without additional fixings.
