The JAZRIDER JR-CR101-LB front knuckle arm kit is an aluminum upgrade made for the TAMIYA CR-01 chassis in scale RC contexts. It swaps in for the factory front knuckle uprights while preserving the original mounting pattern so it can be installed into standard CR-01 steering assemblies.
As a replacement at the chassis level, the metal uprights reduce flex compared with stock plastic parts and help maintain consistent steering geometry throughout tuning and repeated use. The blue anodized finish provides basic corrosion resistance and a distinctive aftermarket look.
Installation note: components are produced to fit CR-01 front knuckle positions. Inspect your current linkage geometry and fasteners prior to installation to ensure the correct toe and steering throw.
Maintenance tip: perform routine inspections of contact faces and fasteners after first runs, and secure steel bolts with thread-lock where vibration is present to prevent loosening.
