TRAXXAS X-MAXX Harden Steel #45 Input Shaft by GPM TXM8035S/S  [TXM8035S/S]

Hardened #45 input shaft for X-MAXX

This is a single aftermarket input shaft designed for RC-scale TRAXXAS X-MAXX powertrains, supplied as 1 pc. Manufactured from hardened steel #45, the straight-shaft geometry aims to give a more precise mechanical hookup to the gearbox and improve long-term wear under heavy drivetrain load within RC use.

Intended role: the shaft replaces the factory input component to restore or increase the reliability and engagement precision of the gear transmission, particularly where higher torque from upgraded setups stresses the drivetrain.

Compatibility notes provided by the source: for 6S use the shaft serves as a direct replacement for the original Traxxas part no. 7786, for 8S use the shaft must be paired with GPM Racing components TXM355315T, TXM355316T, TXM355317T, TXM355318T, TXM355416T, TXM355418T, TXM355515T, or TXM355517T to work with GPM’s no-slip system intended for higher-power 8S configurations.

Installation and tuning role: check fit with the transmission input bore and mating gear, confirm alignment before running, and consider this shaft as a drivetrain upgrade point when refining gear mesh and power delivery for aggressive RC setups.
