TRAXXAS X-MAXX 8S High-Strength Driveshafts 4140 Carbon Steel and 7075 Hex - TXM8170B by GPM  [TXM8170B]

High-strength driveshafts made for X-MAXX 8S

The TXM8170B driveshaft assembly is an aftermarket replacement built for TRAXXAS X-MAXX platforms to swap out front and rear dogbones/CVD links. It mates 4140 medium carbon steel shafts with 7075 alloy hex adapters to increase stiffness and retention for demanding hobby running.

Engineering notes highlight a dogbone diameter increased to 7mm to resist bending on uneven terrain, and a hex adapter fixed with a stainless steel pin through a perforated mount to improve lateral stability compared with the original fixings. The kit ships pre-assembled; applying thread locker to the set screws is recommended to reduce the risk of loosening.

For modelers replacing worn driveline components on TRAXXAS X-MAXX variants, the TXM8170B offers a direct-fit stronger dogbone and a pinned alloy hex for improved lateral control. Adhere to the pre-assembly guidance and secure the set screws with thread locker after fitting.
