This aluminum rear upper suspension arm set is an RC-scale replacement part designed for the Kyosho Fazer Mk2 FZ02 chassis. The gun metal machined arms replace stock plastic components to increase lateral stiffness and provide a consistent mounting surface for the rear suspension links.
Offered as a bolt-on upgrade, the part is limited to the chassis referenced in the product title and supports on-road tuning and routine maintenance. Typical improvements include less rear flex under cornering and more repeatable suspension geometry during setup changes affecting toe, camber, and shock positions.
Installation calls for basic RC tools such as an appropriate hex driver and standard hand tools to remove the original arms and fit the aluminum set. Retain stock hardware unless replacements are supplied and check alignments at each mounting point before final tightening to avoid binding suspension travel.
