Main front shaft for trail crawling

The TRX4037FX front main shaft is built as a replacement for TRAXXAS TRX4 TRAIL CRAWLER rigs, using a steel joint mated to an aluminium shaft body to handle torque from the motor to the front driveline.

The design fits a CVD head on the middle side to increase articulation range and reduce friction where the centre gearbox is near the main shaft, while the cross head sits toward the front gearbox to keep rotation smooth under crawl loads.

Fitting hardware and silicone O-rings are included for installation; the part suits direct service replacement or light tuning of driveline feel on scale trail vehicles.

Yes, the included M4*2.5*11.2 screw shafts and silicone O-rings are intended for standard TRX4 gearbox mounting points.
Yes, fitting the CVD-style head toward the centre gearbox increases allowable steering angle and reduces the risk of binding compared with the reverse orientation.

This assembly is suited to scale trail and recreational crawling; for competitive builds consider verifying compatibility with your specific gearing and motor setup.
