GPM Racing Harden Steel #45 Front/Center/Rear Differential Pinion Gear for Traxxas 1/10 MAXX (TXMS1201S/G2)

Precision pinion replacement for MAXX diffs

This 4-piece pinion gear set is intended as a direct replacement for TRAXXAS MAXX MONSTER TRUCK differential pinions. The TXMS1201S/G2 gears are produced to hardened steel #45 material standards to improve resistance to wear compared with typical softer pinions, providing a firmer and more repeatable mesh under load.

When installed in the front, centre, or rear differential carriers these pinions reduce clearance between mating gears, which can help stabilise the mesh and improve differential reaction. Confirm bearing tolerances and set mesh precisely to avoid excess preload or premature wear.

Recommended for hobbyists seeking a precision hardened replacement to reduce backlash; set mesh and check bearings during fitment for best results.

This item is compatible with

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

What tolerances should I check after fitting?

Verify axial play on the pinion shafts and radial bearing clearance, then set gear mesh so teeth contact evenly without binding.

Is any break-in required for hardened steel pinions?

A short running-in period under light load can help mating surfaces settle; inspect mesh after the first few runs and retighten diff hardware if necessary.

Can these pinions be paired with aftermarket gears?

They are designed to match TRAXXAS MAXX differential geometry; if using non-standard crown or spider gears, verify tooth profile compatibility and mesh before final assembly.

What maintenance extends life of these pinions?

Maintain clean gear oil or grease in the diff, check bearing condition regularly, and avoid sustained overheating or debris ingress. Write Product Review Please sign in your account before you can write any review. Sign In Close
