This machined aluminum main center shaft is made specifically for the Kyosho Fazer Mk2 FZ02 1/10 on-road chassis and carries the model number JR-KFZ200-GU. It is intended as a direct replacement for the central driveline axle to support maintenance and setup work on scale on-road cars.
Compatibility is limited to the Kyosho Fazer Mk2 FZ02 platform as noted in the product name. The gun metal finish balances light weight with durable contact surfaces where the shaft interfaces with bearings and drivetrain components, making it a practical hop-up for repeatable handling changes.
Installation overview: remove the lower drivetrain components following the chassis service points, support the transmission and differential assemblies, withdraw the existing center shaft, install this replacement into the same bearing locations, and then verify clearances and gear mesh before final reassembly. Ensure fasteners are torqued to manufacturer recommendations and that bearings rotate freely after fitting.
Tuning role: a machined aluminum center shaft reduces flex compared with common plastic originals, helping to keep gear mesh consistent and power transfer predictable during suspension or differential tuning sessions. Fit this item when aiming for repeatable driveline behaviour under varying setup conditions.
