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

Front pinion upgrade compatible with TRAXXAS MAXX

This is a single-piece replacement front differential pinion intended for TRAXXAS MAXX scale monster truck drivetrains, offered as an RC aftermarket part by GPM. Crafted from hardened steel #45, the pinion increases durability where it engages inside the differential case, and it is shipped as a 1pcs set.

Installation note: this pinion replaces the stock front differential pinion inside the front differential assembly. When fitting, verify gear mesh and endplay within the differential case, use the correct grease for steel gears, and ensure the differential rotates smoothly before reassembling the gearbox and suspension.

Tuning role: swapping in a hardened steel #45 pinion reduces gear gap and improves repeatability of power transfer through the differential, helping with traction and gearing adjustments on a MAXX platform; it is an aftermarket component for compatible drivetrains only.
