KYOSHO Fazer Mk2 FZ02 Aluminum Center Shaft Cup Joint by JAZRIDER JR-KFZ201-GU  [JR-KFZ201-GU]

Overview

This JAZRIDER JR-KFZ201-GU is an aluminum center shaft cup joint produced for the KYOSHO Fazer Mk2 FZ02 chassis. It is an RC-scale driveline replacement intended to serve where the stock plastic cup may wear or flex under repeated track or street running.

The part uses an aluminum construction and gun-metal finish to provide a metal alternative to the original component. As a direct replacement for the specified Fazer Mk2 FZ02 centre cup joint, it focuses on consistent mechanical fit and longer service life in hobby use cases.

Installation is straightforward for hobby technicians familiar with Fazer Mk2 maintenance: remove the stock cup joint from the center shaft and swap in the aluminum unit using the original hardware. After installation, check driveline alignment and free rotation to ensure correct engagement with surrounding couplers and bearings.

Tuning role: this aluminum cup joint changes the drivetrain’s stiffness characteristics compared to stock plastic; builders typically consider it when pursuing incremental durability upgrades or when aiming for more consistent feedback under sustained running conditions.
