This precision-machined aluminum main center shaft is produced for the Kyosho Fazer Mk2 FZ02 1/10 on-road chassis and is listed under model JR-KFZ200-GU. It functions as a direct replacement part for the central driveline axle to aid hobbyists in maintenance and fine tuning.
The part is compatible only with the Kyosho Fazer Mk2 FZ02 chassis as identified in the product title. The gun metal finish aims to combine reduced flex with improved bearing contact areas where the shaft meets other drivetrain components, making it useful as an aftermarket hop-up.
Fitting notes: follow the chassis service procedures to remove the lower drivetrain pieces, support the transmission and differential assemblies, extract the original center shaft, insert this replacement into the correct bearing seats, and check gear mesh and clearances prior to final reassembly. Confirm proper torques and free bearing rotation after installation.
Performance note: replacing a stock plastic shaft with a machined aluminum unit can lower flex under load, which supports consistent gear mesh and more predictable power delivery while making suspension or diff adjustments. Use this shaft when seeking steadier driveline responses during setup changes.
