The JR-KFZ205-BK rear upper suspension arm set is an aftermarket RC replacement intended for the KYOSHO Fazer Mk2 FZ02 on-road chassis. Finished in black anodized aluminium, the components provide an alternate rear upper suspension mounting choice for that chassis.
Compatibility is restricted to the named Fazer Mk2 FZ02 platform; confirm chassis code before fitting. The aluminium construction changes stiffness characteristics relative to stock options and is used by hobbyists to influence rear suspension behaviour.
Installation notes: the arms mount at the existing rear upper points and are designed to use the Fazer Mk2 FZ02 original mounting interfaces. Check alignment, travel clearance and that fasteners are secure to preserve predictable handling.
Tuning role: installers choose this aluminium arm set to adjust rear geometry or to obtain a firmer rear upper connection point for improved traction consistency or more immediate transient response. After fitting verify ball stud heights and droop settings to maintain expected roll and rebound balance.
