This single 74mm swing shaft comes supplied as 1 pcs for RC-scale drivetrains and is listed for use with Universal, SB and ZX7.5 model platforms. It is intended to replace worn shafts and re-establish correct driveline geometry.
When fitting the shaft, confirm axial alignment, ensure universal joints turn freely, and check mounting bore clearance to avoid binding during suspension movement. A correct fit supports steady power transfer and predictable handling characteristics under different setup conditions.
Presented as a maintenance replacement rather than a tuning item, confirm compatibility with your chassis and perform a trial fit before final reassembly of drivetrain parts.
Keep this item as a spare to quickly address worn drivetrain components and reduce service time.
