KYOSHO Fazer Mk2 FZ02 Aluminum Rear Upper Suspension Arm Set (Blue) by JAZRIDER JR-KFZ205-LB  [JR-KFZ205-LB]

Rear Upper Suspension Arm Set

This aluminum rear upper suspension arm set is made for RC-scale use on the Kyosho Fazer Mk2 FZ02 chassis. The component replaces the standard plastic upper arms to provide a durable, metal option for routine running and incremental tuning of the rear suspension geometry. The blue anodized finish identifies the part visually without affecting fitment.

Installation is straightforward for hobbyists familiar with on-road maintenance: remove the original rear upper arms, retain or inspect existing ball studs and hardware for wear, fit the aluminum arms into the same mounting points, and verify free range of motion through the suspension travel. Use common hand tools and check fasteners after a short test run.

In tuning terms this part acts as a direct hop-up: it increases structural stiffness at the rear upper suspension link, which can change roll characteristics and steering response when combined with spring, damper, and toe settings. Adjust other suspension parameters gradually and test on a controlled surface to find the balance you want.
