Technical Overview of 4140 Rear Driveshafts for TRAXXAS MINI XRT VXL 3S

GPM's TRAXXAS MINI XRT VXL 3S rear driveshafts and drive cups are precision engineered from 4140 carbon steel to provide enhanced tensile strength and superior wear resistance compared to factory items. The hardening black treatment increases surface hardness and fatigue life, while the CVD-style dog bone geometry allows greater steering angle and smoother rotational transmission. The specified length is 61mm from the dog bone end to the midpoint, engineered for consistent torque transfer and reliable drivetrain performance.

What mechanical benefits does 4140 steel provide for driveshafts?

4140 steel offers a balance of toughness and hardness that improves resistance to bending and surface wear, reducing the frequency of replacements in high load scenarios.

Are there special torque values for the set screws?

Use medium-strength thread locker and tighten set screws to a moderate torque that secures the cups without risking screw shear; refer to common M4 torque charts for guidance.

How should these parts be inspected after hard use?

Inspect for straightness, surface nicks, and secure set screws. Check that the CVD joints rotate freely through full steering lock to detect early wear or binding.
