This is an RC-scale aluminum replacement for the front lower suspension arms intended for Tamiya TA07 and TB04 Pro II chassis. The JR-TA706-GU arms come in a gun metal finish and provide a firmer mounting point compared with standard plastic arms, aimed at hobby drivers tuning on track.
The arms are manufactured as direct replacements for the specified Tamiya models and maintain the stock suspension geometry. When fitting, confirm pivot-pin alignment and check clearance around the steering link and upright. Standard workshop tools such as hex drivers and pliers are normally sufficient for installation; no special adapters are required.
As a tuned hop-up part, these aluminum arms reduce flex under load and deliver a more consistent front-end feel during setup iterations. Inspect all mounting hardware during installation and verify roll-center and toe settings after fitting to retain intended handling characteristics.
