GPM Racing Harden Steel #45 Front Differential Ring Gear & Pinion Gear for Traxxas 1/10 MAXX (TXMS1200FS)

Front ring and pinion - precision upgrade

This front differential ring and pinion set is specified for the TRAXXAS MAXX platform and manufactured in hardened steel #45 for improved gear contact and reduced clearance. The parts replace the stock ring and pinion inside the front differential case to minimise backlash and stabilise torque transfer under high load conditions.

Intended for hobbyists seeking a precision upgrade, the set supports more consistent drivetrain behaviour through tighter tooth engagement. Installation requires removal of the front differential cover and standard RC workshop tools; correct mesh setting and bearing condition should be verified during assembly.

Packing includes

• Ring Gear - 1 pcs
• Pinion Gear - 1 pcs

Original Name / Part No:

Improve the transmission of power in the differential case.

Select this set for a durable, precision front differential replacement; verify correct gear mesh during installation and recheck after a controlled break-in to ensure long term reliability.

This item is compatible with

• TRAXXAS-1/10 MAXX MONSTER TRUCK-89076-4
• MAXX W/WIDEMAXX MONSTER TRUCK-89086-4

What inspection should be done before fitting?

Inspect differential bearings and shafts for play or wear, clean mating surfaces, and ensure the existing housing is free from damage to achieve correct alignment.

How should I set gear mesh for best results?

Use a consistent feeler method or shim technique to obtain a small running clearance; confirm smooth rotation by hand and check under light load before final torqueing.

Are there any break-in procedures to follow?

Run the vehicle at low speed initially to allow parts to seat, monitor for unusual noise, then recheck mesh and fasteners after short test runs.

What advantages does hardened steel #45 provide?

Hardened steel #45 enhances wear resistance and helps preserve tooth geometry under repeated loading, improving the consistency of power transfer in demanding conditions. Write Product Review Please sign in your account before you can write any review. Sign In Close
