This aluminium universal swing drive shaft set is intended for Kyosho Optima 2016 chassis maintenance and tuning, replacing stock swing drive pieces with more stable aluminium parts that transfer gearbox output to the wheels.
The JR-OT06 set serves as a direct replacement for worn components or as a hop-up when adjusting drivetrain backlash and alignment. Aluminium provides consistent dimensional stability compared with softer materials and is intended to fit the Optima 2016 swing drive geometry.
Installation guidance: check shaft fit with the gearbox output and CVD or universal joints before final assembly, ensure grub screws or retaining clips are torqued to the chassis manufacturer's recommended values, and confirm clearance with suspension travel and wheel hubs. After installation, verify smooth rotation at static and under load to detect binding before full-speed testing. This description refers only to RC model use.
