TRAXXAS X-MAXX 8S Driveshaft Upgrade 4140 Steel Dogbones with 7075 Hex - TXM8170B by GPM  [TXM8170B]

Heavy-duty driveshaft replacement for X-MAXX 8S

This TXM8170B driveshaft assembly is an aftermarket RC-scale replacement 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 increase component stiffness and improve retention during demanding hobby use.

Key design notes come from the supplied parts list and suggested revisions: the dogbone diameter has been increased to 7mm from the original smaller diameter to resist bending on rough terrain, and the alloy hex features a perforated mount secured by a stainless steel pin rather than the stock 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 operation.

For hobbyists replacing worn driveline parts on TRAXXAS X-MAXX variants, the TXM8170B assembly offers a direct-fit, tougher dogbone option with a pinned alloy hex. Follow pre-assembly notes and secure set screws with thread locker when installing to maintain long-term stability.
