TRX4 Differential Bevel and 11T Pinion 34T 40CR Steel Replacement - TRX41134T by GPM  [TRX41134T]

Precision 40CR bevel and pinion for TRX4 inner gearboxes

This replacement set supplies the internal differential bevel and matching pinion used in TRX4-type trail crawlers. The kit contains a 34T bevel differential gear and an 11T pinion gear manufactured in 40CR steel for scale RC drivetrain use.

Designed to mount in the inner area of the front or rear gearbox, the bevel set transfers torque from the motor output to the axle shafts. These aftermarket gears restore correct tooth engagement and consistent torque delivery for crawling applications.

Assembly best practice: verify gear mesh and backlash relative to the existing spur and pinion prior to final assembly, inspect the gearbox for contaminants, and apply a suitable metal-to-metal RC gear grease to all mating teeth to reduce wear under low-speed loads.

Use this 40CR bevel and pinion to replace worn internal diff gears and recover precise drivetrain engagement and long term durability in TRX4 and compatible TRX-6 gearboxes.
