TRAXXAS Unlimited Desert Racer 1/7 Planetary Ring Gear 40Cr Hardened - UDR041TS by GPM  [UDR041TS]

40Cr Hardened Planetary Ring Gear

This aftermarket planetary ring gear is a direct-replacement part compatible with the TRAXXAS Unlimited Desert Racer 1/7 platform. Machined from 40Cr carbon steel with a supplier-specified black hardening finish, the gear is intended to deliver improved surface wear resistance compared with the stock component. It is supplied as a single spare for the listed TRAXXAS models and fits into the planetary gearbox path on scale 1/7 desert racer builds.

Fitting requires opening the gearbox and removing the planetary carrier to swap out the worn ring gear. While the gearbox is disassembled, inspect bearing condition and carrier surfaces, set correct gear mesh, and verify clearances; correct mesh and solid bearing support reduce premature wear and help keep transmission behaviour consistent under load. This item is sold as the single ring gear only and does not include extra fasteners.

Choose this 40Cr steel ring gear when replacing worn drivetrain components or when you need a more wear-resistant spare; confirm fit and mesh at reassembly to preserve gearbox reliability on your scale 1/7 TRAXXAS setup.
