TRAXXAS MAXX Rear Differential Ring & Pinion Hardened #45 3pc Set TXMS1200RS by GPM  [TXMS1200RS]

Rear differential steel ring and pinion set

This 3pcs aftermarket differential gear set is built for TRAXXAS MAXX rear differentials, replacing the stock rear ring and pinion with hardened steel #45 items and supplying a stainless steel retention pin for assembly security.

The hardened #45 material increases resistance to wear during heavy use, while tighter production tolerances cut down gear lash so the drivetrain engages more smoothly and consistently. Those improvements help when tuning diff preload or troubleshooting drivetrain noise.

Fitment notes: remove the differential case as per your service instructions, install the new ring and pinion, verify the retaining pin alignment and endplay, then check gear mesh by hand rotation before final assembly. Apply threadlocker or approved retaining methods where necessary.

As a direct replacement, the TXMS1200RS set focuses on rear diff longevity and more reliable gear engagement for TRAXXAS MAXX enthusiasts.
