TRAXXAS X-MAXX 8S 4140 Medium Carbon Steel Front/Rear Driveshaft with 7075 Alloy Hex by GPM TXM8170B  [TXM8170B]

Replacement driveshafts for X-MAXX 8S

This GPM TXM8170B driveshaft assembly is an aftermarket RC-scale replacement designed for TRAXXAS X-MAXX platforms. The kit replaces front and rear dogbones/CVD connections and pairs 4140 medium carbon steel shafts with 7075 alloy hex adapters to improve component stiffness and retention under high-load hobby use.

Key design notes come from the supplied parts list and factory modifications: the dogbone diameter has been increased to 7mm from the original smaller diameter to resist bending on rough terrain, and the alloy hex uses a perforated mount secured by a stainless steel pin rather than the original fastening method for improved lateral stability. All included accessories arrive pre-assembled, and the manufacturer recommends using thread locker on the set screws to reduce the chance of loosening during use.

For hobbyists replacing worn driveline parts on TRAXXAS X-MAXX variants, this GPM assembly offers a direct-fit RC-scale option with tougher dogbones and a pinned alloy hex. Follow the pre-assembly notes and secure set screws with thread locker when installing to maintain long-term stability.
