The 3Racing FW05-021 transmission shaft is crafted to be a reliable upgrade for Kyosho FW05-R and FW05RR cars, improving torque delivery and gearbox harmony. Precision finishing helps maintain consistent engagement and reduces erratic drivetrain behaviour on track.
Engineered to resist surface fatigue and deformation, the 3Racing shaft extends component life compared to standard shafts. Its robust construction helps keep settings stable across multiple race meetings.
Specifically sized for the Kyosho FW05-R and FW05RR layout, the FW05-021 installs with existing transmission hardware. This makes it an efficient upgrade for anyone replacing tired internals or tightening drivetrain feel.
