Upgraded shaft set for X-MAXX 8S applications

The TXM8170B driveshaft assembly is an aftermarket replacement for TRAXXAS X-MAXX platforms, designed to replace the standard front and rear dogbones/CVD links. It combines 4140 medium carbon steel shafts with 7075 alloy hex adapters to boost stiffness and component retention during high-load hobby use.

Design highlights include an increased dogbone diameter of 7mm to reduce bending on rough surfaces, and a hex adapter that uses a perforated mount secured by a stainless steel pin instead of the original fastening method to improve lateral stability. Parts are supplied pre-assembled, and it is advised to use thread locker on set screws to minimize loosening during running.

Packing includes

  • Driveshaft - 2pcs
  • Hex Adapter - 2pcs
  • Set Screws 4x3 - 2pcs
  • Steel Pin 4x17.8 - 2pcs

When replacing worn driveline components on TRAXXAS X-MAXX variants, the TXM8170B set provides a tougher alternative with a pinned 7075 hex for added lateral control. Follow the installation notes and secure fasteners with thread locker for reliable service.

What are the shafts and hex adapters made from?

The dogbones are made from 4140 medium carbon steel and the hex adapters are machined from 7075 alloy to increase strength compared with typical stock components.

How does the larger diameter help in practice?

Increasing the shaft diameter to 7mm reduces flex and the risk of bending when running over rough terrain or under hard acceleration.

Are the parts drop-in replacements?

These components are intended as direct-fit aftermarket replacements for compatible TRAXXAS X-MAXX models listed above; verify fit before full installation.

Any care tips to extend service life?

Regularly inspect set screws and pins, reapply thread locker if needed, and check for wear after heavy runs to prolong component life.
