The 3Racing FW05-021 transmission shaft is intended as a durable upgrade for Kyosho FW05-R and FW05RR cars, improving power transfer consistency under load. Careful machining and a durable finish help the shaft resist chipping and deformation in aggressive use.
With a focus on longevity, the 3Racing shaft offers higher resistance to surface wear and bending than many stock alternatives. That makes it a sensible choice for drivers who push hard and want fewer gearbox issues.
Made to slot into the FW05-R and FW05RR transmission layout, the FW05-021 simplifies upgrades without major disassembly or modification, letting you get back to testing line and tyre changes faster.
