This aluminium A5 replacement part is an RC-scale front suspension arm mount and gearbox support intended for the Tamiya buggy chassis lines named above. It replaces the stock A5 plastic assembly with a black anodised aluminium unit to reduce front flex and provide a firmer mounting point for the gearbox and suspension links.
Installation uses the original A5 mounting locations so the component fits where the stock front mount sits on compatible Tamiya chassis. As a structural hop-up it influences steering feel and front-end response, useful for chassis setup or when repairing a damaged original mount.
Fitting advice: confirm gearbox alignment and suspension arm positions during reassembly, reuse original fasteners only if they are serviceable, and check threads after the first test runs. The black anodise is cosmetic while the aluminium body provides greater rigidity vs common plastic mounts.
