This is a single 74mm swing shaft intended for RC-scale drivetrains, supplied as 1 pcs for direct replacement use. The part is specified for compatibility with Universal, SB and ZX7.5 model platforms as listed by the original reference, and is intended to restore correct driveline geometry where the original shaft shows wear.
In practical use the swing shaft serves as a direct link in the drivetrain assembly; during fitment verify axial alignment and free rotation of connected universal joints, check mounting bore clearance, and confirm there is no binding across suspension travel. A precise fit helps maintain predictable power transfer and consistent handling during setup and tuning.
The component is presented as a straightforward spare for maintenance or margin tuning rather than a performance upgrade; confirm compatibility with your chassis configuration and test fit before reassembling final driveline components.
Keep this part as a service spare in your maintenance kit to minimise downtime when addressing worn or damaged drivetrain components.
