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

Heavy-duty #45 input shaft for X-MAXX use

This aftermarket input shaft suits TRAXXAS X-MAXX powertrains and is supplied as 1 pc. Forged from hardened steel #45, the straight shaft geometry improves gearbox coupling and extends service life under heavy RC loading.

Intended role: designed to replace the factory input shaft to increase reliability and improve the precision of gear engagement, particularly where upgraded motors or tougher terrain increase drivetrain demands.

Compatibility notes provided by the source: for 6S installations the shaft replaces Traxxas part no. 7786 directly. For 8S the shaft must be paired with the specified GPM Racing components to operate with the no-slip 8S configuration: TXM355315T, TXM355316T, TXM355317T, TXM355318T, TXM355416T, TXM355418T, TXM355515T, TXM355517T.

Installation and tuning role: check bore fit and gear alignment before powering up. Use this shaft as a key upgrade point when optimising gear mesh and torque transfer in high-performance RC setups.
