The kit comprises a 33T differential bevel gear paired with a 12T pinion, both fabricated from 40CR steel and intended as a drivetrain spare for TRAXXAS TRX4-series crawlers and compatible TRX6 chassis. The components locate inside the front or rear gearbox to convey torque through the differential.
Replace worn plastic or alloy gears with this set during maintenance or when performing a gearbox swap. The 40CR material delivers a balance of durability and wear resistance suitable for scale trail crawling; inspect gear mesh, bearing play and alignment during fitting to reduce risk of early wear.
Fitting guidance: remove the gearbox cover, retain shims and bearings in their original positions, install bevel and pinion in the same orientation as removed, then verify correct backlash and free rotation before closing the case. For model use only.
