This JAZRIDER JR-CR101-LB part is an aluminum front knuckle arm set intended for RC-scale use on the TAMIYA CR-01 chassis. The piece replaces the stock front knuckle uprights with a metal option, maintaining the original mounting arrangement for use in standard CR-01 steering assemblies.
Built as a chassis-level spare, the upright provides a consistent metal interface where plastic parts are commonly used, which helps preserve steering geometry during repeated runs and tuning sessions. The blue finish identifies the part visually while matching common aftermarket styling on scale rigs.
Installation note: the component is produced to align with CR-01 mounting points and is intended to fit the front steering knuckle positions. Check your existing hardware and steering linkages for compatibility before installation to ensure correct fit and neutral toe settings.
Maintenance tip: inspect mating surfaces and fasteners regularly for wear and tightness after initial runs, and use thread-lock on steel fasteners where applicable to prevent loosening from vibration.
