Traxxas Xmaxx 8S CVD shafts hardened steel #45 upgrade TXM8170N/2 by GPM  [TXM8170N/2]

Reinforced CVD kit for Xmaxx performance

This replacement CVD set is made for Traxxas Xmaxx 8S applications where increased rpm and torque demand tougher driveline components. The design uses hardened steel #45 for core drive parts and revised joint geometry to improve stability at high rotational speeds.

The package replaces dogbone-style pieces with thicker hard-steel parts, increasing the dogbone section from 5.5mm to 7mm as supplied, and changes the CVD-to-hex interface to a stainless steel pin through a perforated joint rather than the original fastening method. These updates reduce runout and help keep the wheel hex secure under heavy throttle and high-speed runs.

Installation notes: the set includes alloy hex adapters and requires basic drivetrain disassembly to replace front or rear CVDs. Maintain tight tolerances and check hub to hex alignment to avoid premature wear on bearings and gear interfaces. This is sold as an aftermarket upgrade for RC use only.

This GPM TXM8170N/2 CVD set provides a hardened-steel aftermarket option for Traxxas Xmaxx 8S owners wanting stronger hex retention and reduced driveline flex; perform standard drivetrain checks when fitting.
