Kyosho FW05-R/FW05RR Centre Shaft Join Aluminium Upgrade - FW05-015 by 3Racing  [FW05-015]

Aluminium centre shaft join tailored to FW05 chassis

This aluminium centre shaft join is an RC replacement part for the Kyosho FW05-R and FW05RR platforms, listed as FW05-015. It replaces the original centre coupling to create a firmer material connection between shaft segments while keeping description to the observed effect of higher material stiffness.

Compatibility is confined to the FW05-R and FW05RR variants shown in the title, so confirm dimensional fit before fitting the part. Aluminium is often preferred to limit deformation compared with standard plastic joins in similar roles.

Fitting guidance: the join sits at the mid-point of the driveline where shaft sections meet, using the chassis' existing fasteners and locating points. Maintain straight shaft alignment to avoid binding and verify runout after installation. As a tuning component it is commonly used to reduce driveline play and provide a firmer connection point when adjusting differential and drivetrain settings.
