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

Reinforced #45 input shaft for X-MAXX powertrains

This is a single aftermarket input shaft intended for TRAXXAS X-MAXX drivetrains, supplied as 1 pc. Constructed from hardened steel #45, the straight shaft form provides a more precise mating with the gearbox and greater longevity under high drivetrain stress.

Intended role: fitted to replace the original input component, this shaft improves engagement precision and helps prevent premature wear when upgraded motors or higher torque loads are applied.

Compatibility notes provided by the source: for 6S the shaft acts as a direct replacement for Traxxas part no. 7786. For 8S installations the shaft must be combined with the GPM Racing parts listed to operate with the no-slip 8S solution: TXM355315T, TXM355316T, TXM355317T, TXM355318T, TXM355416T, TXM355418T, TXM355515T, TXM355517T.

Installation and tuning role: confirm alignment and clearance with the transmission input bore and mating gear. Consider this shaft when adjusting gear mesh and power distribution in high-torque or competition-oriented setups.
