The 3RACING Crawler Ex Real Transmission Swing Shaft Join (CRA-120) is designed with racing setup needs in mind, delivering stable coupling and predictable drivetrain behaviour under load. It matches the geometry of Crawler Ex Real kits to preserve alignment and minimise drivetrain lash.
Engineered to support consistent torque transmission, the CRA-120 reduces transient movement in the drivetrain and helps maintain wheel contact during technical manoeuvres. Its predictable behaviour aids setup tuning and repeatable runs.
Intended for use with Crawler Ex Real series components, the CRA-120 installs without major modification. For competitive use, verify shaft endplay and check coupling interfaces as part of your baseline setup routine.
