TRAXXAS UDR 1/7 Planetary Ring Gear 40Cr Wear-Resistant - UDR041TS by GPM  [UDR041TS]

Hardened 40Cr Planetary Gear

This replacement planetary ring gear is a purpose-made spare for the TRAXXAS Unlimited Desert Racer 1/7 platform. Crafted from 40Cr carbon steel with a black hardening treatment specified by the supplier, the part aims to improve surface wear life over the original unit. It fits into the planetary assembly and is intended as a single replacement component for the models listed.

Installation involves basic gearbox disassembly to access the planetary carrier and swap the ring gear. While working inside the gearbox, check bearing fit, carrier condition and gear alignment; maintaining correct mesh and bearing support reduces uneven wear and preserves gearbox performance under sustained loads. Note that only the ring gear is included; no additional hardware is supplied.

Use this hardened 40Cr ring gear when replacing worn drivetrain parts or when upgrading for better wear resistance; always verify mesh and bearing support during reassembly to keep your 1/7 TRAXXAS gearbox dependable.
