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

Performance #45 input shaft for X-MAXX transmissions

This single aftermarket input shaft is intended for TRAXXAS X-MAXX powertrains and is supplied as 1 pc. Manufactured from hardened steel #45, the straight-shaft design aims to provide tighter gearbox engagement and better resistance to wear in demanding RC conditions.

Intended role: the shaft replaces the original input to improve engagement precision and to enhance drivetrain reliability when higher torque or more aggressive tuning increases operational stress.

Compatibility notes provided by the source: for 6S use the shaft is a direct replacement for Traxxas part no. 7786. For 8S use it must be paired with the following GPM Racing parts to function with the no-slip 8S arrangement: TXM355315T, TXM355316T, TXM355317T, TXM355318T, TXM355416T, TXM355418T, TXM355515T, TXM355517T.

Installation and tuning role: confirm correct fit and alignment with the transmission input bore and mating gear before running. Consider this shaft when refining gear mesh and power transfer for high-demand RC builds.
