Designed for the Kyosho Fazer Mk2 FZ02 chassis, this rear upper suspension arm set swaps out the original plastic pieces for a stronger aluminum option built for repetitive on-road use. The blue anodize helps protect the metal and makes inspection easier without changing how the parts fit.
Installation uses the factory mounting points: remove the stock upper arms, confirm the condition of ball studs and mounting hardware, install the alloy replacement arms, and verify unhindered suspension travel. Simple hand tools are all that is required and a post-install fastener check is advised.
Functionally the kit provides a stiffer upper rear link that can reduce flex and extend component life. Expect changes to rear roll and transient steering feel; tune suspension progressively to achieve the desired handling characteristics.
