TRAXXAS TRX4 Front CVD Main Shaft TRX4037FX by GPM  [TRX4037FX]

Front main shaft for scale trail use

The TRX4037FX front main shaft is an RC-scale replacement compatible with the TRAXXAS TRX4 TRAIL CRAWLER platform, marrying a steel joint to an aluminium body to manage motor torque to the front axle.

The assembly fits a CVD head on the centre side to allow greater articulation and reduce friction where the centre gearbox is close to the shaft, with the cross head toward the front gearbox to preserve smoother driveline rotation during crawling.

Included are mounting screws and silicone O-rings for straightforward assembly; pick this part as a direct-service spare or a modest hop-up to refine driveline feel and toughness on scale trail rigs.

Fit this assembly to replace worn front shafts or when tuning driveline responsiveness for scale trail crawling, and follow routine checks for alignment and lubrication after fitting.
