TRAXXAS TRX-4 Steel Center Universal Drive Shaft by JAZRIDER JR-TRX415-BK  [JR-TRX415-BK]

Center universal drive shaft for TRX-4

This steel center universal drive shaft is a direct-fit replacement option offered by JAZRIDER for Traxxas TRX-4 scale crawlers. It is intended as an RC-scale driveline component to replace or upgrade the factory center shaft and to provide a durable connection between front and rear drivetrains.

In practical terms the part supports regular trail and rock crawling use on scale rigs. When evaluating fitment verify the supplier listing and vehicle build details for any modifications or aftermarket adaptors that might be present on your chassis. The shaft should be installed and checked for smooth articulation through full suspension travel to avoid binding.

The component plays a tuning role by offering a stiffer, wear-resistant center connection compared with some stock alloy or composite shafts, helping maintain alignment under load and reducing driveline play that can affect low-speed crawling performance.

Use this steel center shaft as a service replacement or an incremental upgrade on TRX-4 scale crawlers, and verify alignment and articulation after installation to ensure consistent driveline performance.
