JAZRIDER JR-KFZ205-GU KYOSHO Fazer Mk2 FZ02 Rear Upper Suspension Arm Set  [JR-KFZ205-GU]

Rear upper arm upgrade for Fazer Mk2 FZ02

This aluminum rear upper suspension arm set is an RC-scale replacement part designed for the Kyosho Fazer Mk2 FZ02 chassis. Finished in gun metal, the machined aluminum pieces act as direct-replacement hop-ups to increase lateral stiffness compared with typical stock plastic arms and to provide a consistent mounting surface for the rear suspension links.

Compatibility is limited to the chassis named in the product title, and the part is offered as a bolt-on upgrade for on-road tuning and maintenance. Typical benefits in an RC context include reduced flex under cornering loads and more repeatable rear geometry during setup changes, which helps when adjusting toe, camber, or shock mounting positions.

Installation requires basic RC tools such as an appropriate hex driver and common hand tools to remove the original arms and refit the aluminum set. Retain or reuse the stock hardware unless the kit explicitly provides replacement fasteners, and check fitment at each mounting point before final tightening to avoid binding the suspension travel.
