TRAXXAS TRX4 Trail Crawler 40CR Steel Differential Bevel Gear 34T & Pinion Gear 11T by GPM TRX41134T  [TRX41134T]

Steel differential bevel and pinion for TRX4

This GPM gear set replaces the internal differential bevel and the matching pinion for TRAXXAS TRX4-based trail crawlers. The kit consists of a 34T bevel differential gear and an 11T pinion gear manufactured in 40CR steel, intended for RC-scale drivetrain use only.

Fitment is intended for the inner area of the front or rear gearbox where the differential bevel set transmits torque between the motor output and wheel axles. The components are aftermarket replacements that focus on restoring proper gear mesh and consistent power transfer in crawler setups.

Installation notes: verify gear mesh and backlash with your existing spur and pinion before final assembly, inspect the gearbox internals for debris, and lubricate mating teeth with an appropriate RC gear grease. These steps help reduce premature wear and maintain smooth low-speed crawling performance.

Use this steel bevel and pinion set when replacing worn internal diff gears in TRX4/TRX-6 gearboxes to regain consistent drivetrain engagement during low-speed crawling.
