TRAXXAS MAXX Front Differential Pinion Hardened Steel #45 TXMS1200F/G2 by GPM  [TXMS1200F/G2]

Replacement front differential pinion for TRAXXAS MAXX

This single-piece front differential pinion is designed for TRAXXAS MAXX scale monster truck drivetrains and sold as an aftermarket component by GPM. Manufactured from hardened steel #45, the pinion increases resistance to wear where it meshes inside the differential case, and it ships as a 1pcs set.

Installation note: the part installs into the front differential assembly to replace the original front pinion. When fitting, set correct mesh and endplay in the differential case, apply suitable steel gear lubrication, and confirm smooth differential rotation before putting the gearbox and suspension back together.

Tuning role: installing a hardened steel #45 pinion aims to tighten gear clearance and deliver more consistent power transfer through the differential, which can be useful when tuning traction or changing final drive ratios on a MAXX chassis; this is an aftermarket upgrade for compatible drivetrains only.
