This single 74mm swing shaft is produced for RC-scale drivetrains and supplied as 1 pcs for direct replacement. The item lists compatibility with Universal, SB and ZX7.5 platforms and is intended to correct driveline geometry where an original shaft shows wear.
When fitting, check axial alignment and confirm the connected universal joints rotate freely; inspect mounting bore clearance and ensure there is no binding during full suspension travel. A precise installation helps keep power transfer consistent and predictable in handling.
Consider this component a service spare for routine maintenance rather than a tuned performance upgrade; always verify chassis compatibility and perform a test fit before completing final assembly.
Store this shaft in your maintenance kit to reduce downtime when replacing worn or damaged drivetrain parts.
