TRAXXAS Unlimited Desert Racer 1/7 Steel Planetary Ring Gear by GPM UDR041TS  [UDR041TS]

Steel Planetary Ring Gear

This replacement planetary ring gear is an RC-scale drivetrain component produced by GPM for the TRAXXAS Unlimited Desert Racer 1/7 platform. It is machined from 40Cr carbon steel and receives a hardening black treatment as specified by the supplier, aimed at improving surface wear resistance compared with the original part. The gear is intended as a direct spare for the listed TRAXXAS models and serves the gearbox transmission path in scale 1/7 desert racer builds.

Installation requires gearbox access and basic disassembly of the planetary carrier to remove the existing ring gear and fit the replacement. Check alignment, clearances, and bearing condition while the gearbox is open; correct mesh and proper bearing support help maintain consistent transmission behaviour under load. This part is supplied as a single replacement gear and does not include additional hardware.

Use this 40Cr steel ring gear when replacing worn drivetrain components or when upgrading to a more wear-resistant spare; verify fit and mesh during reassembly to maintain gearbox reliability in your scale 1/7 TRAXXAS setup.
