TRAXXAS MAXX Differential Ring Gear Harden Steel #45 - TXMS12F/R/G1 by GPM  [TXMS12F/R/G1]

Hardened #45 steel ring for MAXX differentials

This aftermarket ring gear is supplied as a single 1pc replacement tailored for the TRAXXAS MAXX monster truck drivetrain. Machined from Harden Steel #45, the component aims to tighten gear mesh and improve torque transfer inside the differential case without changing the factory layout.

Role and tuning effect: replacing a worn or stock ring gear with a hardened #45 steel unit reduces backlash between mating gears, resulting in a crisper differential feel under load and steadier power delivery during hard acceleration. It is a practical drivetrain reinforcement for hobbyists seeking greater durability and more consistent gear engagement.

The ring gear serves as a direct upgrade for MAXX owners wanting a tougher, lower-backlash internal gear to better handle aggressive running; always check your MAXX differential case dimensions for fitment before installing.
