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

Front differential pinion gear for TRAXXAS MAXX

This is a single‑piece replacement front differential pinion gear designed for use on TRAXXAS MAXX scale monster truck drivetrains, supplied as an RC‑scale aftermarket part by GPM. The gear is made from hardened steel #45 to increase wear resistance where the pinion meshes inside the differential case, and it ships as a 1pcs set.

Installation note: this pinion fits into the front differential assembly and replaces the stock front differential pinion gear. When installing, check mesh and endplay in the differential case, use correct lubrication for steel gears, and verify smooth rotation of the differential before reassembling the gearbox and suspension components.

Tuning role: swapping to a hardened steel #45 pinion is intended to reduce gear gap and improve consistency of power transfer through the differential, which can help when tuning traction or gearing on a scale MAXX setup; it is an RC accessory and should be used only on compatible model drivetrains.
