X-MAXX 8S dogbone and hex adapter upgrade

The TXM8170B driveshaft assembly is an aftermarket option for TRAXXAS X-MAXX vehicles, replacing the standard front and rear dogbone/CVD assemblies. It pairs 4140 medium carbon steel shafts with 7075 alloy hex adapters to raise stiffness and retention under heavy hobby use.

Notable design choices include a 7mm dogbone diameter increase to better resist bending on rough tracks, and a hex adapter secured with a stainless steel pin through a perforated mount for enhanced lateral stability versus the original fastener. Items ship pre-assembled; using thread locker on the set screws is recommended to reduce loosening during running.

Packing includes

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

For enthusiasts upgrading driveline toughness on TRAXXAS X-MAXX models, the TXM8170B set provides a stiffer shaft and a pinned alloy hex for stronger retention. Observe the pre-assembly notes and secure the set screws with thread locker when fitting.

Will these change throttle response or feel?

Upgrading to stiffer 4140 shafts reduces drivetrain flex, which can make power delivery feel more direct under load but will not alter electronic throttle mapping.

Do hex adapters improve wheel retention?

The 7075 alloy hex with a pinned perforated mount enhances lateral retention versus some stock designs, lowering the chance of slippage under extreme cornering.

Is any drilling or trimming required?

The kit is intended as a direct replacement; check clearances if you run oversized tires or modified suspension travel to ensure no interference.

Recommended maintenance after installation?

Inspect pins and set screws after a few test runs, reapply thread locker as required, and monitor for any unusual wear patterns on long runs.
