Traxxas X-MAXX 6S Harden Steel #45 CVD with Alloy Hex by GPM TXM170N/2  [TXM170N/2]

Hardened CVD Upgrades for X-MAXX 6S

This 16pcs replacement set is an aftermarket CVD (constant velocity drive) assembly designed for Traxxas Xmaxx 6S duty. The kit uses hardened steel #45 for the primary drive components, with the dogbone thickness increased from the original 5.5mm to 7mm to better handle high rotational speed and torque from a 6S setup. The CVD-to-hex joint departs from a simple clamp fastener and uses a perforated interface secured by a stainless steel pin to stabilize the alloy hex under load.

Included hardware supports installation and retention: four hex adapters, four stainless steel screw shafts M5x4x20, and four set screws 5x5, matching the supplied manual reference numbers 7750, 7737, and 7756. The assembly is intended to lead the wheels and tires to rotate with improved durability compared with the stock parts when running high-power setups.

For tuning and maintenance this kit focuses on replacing the stock soft components with hardened steel parts to reduce deformation at high RPM and to keep wheel tracking consistent during aggressive use. The alloy hex interface combined with the pinned joint aims to reduce slop between the CVD and wheel hex under heavy acceleration.

Fitment is specifically for Traxxas Xmaxx 6S applications, use this hardened #45 CVD set where increased drivetrain stiffness and joint stability are required to maintain consistent wheel rotation under high loads.
