This JAZRIDER JR-TT105-BK set provides aluminum rear upper suspension arms designed for TAMIYA TT01 and TT01E scale RC chassis. The components are intended as direct replacements for the factory plastic upper arms, matching the original mounting points so they integrate with stock hinge locations and common rear suspension layouts.
In practical setup work these aluminum arms act as a more rigid mounting point for the rear suspension geometry, helping maintain consistent alignment during tuning sessions. They are suitable where hobbyists focus on repeatable suspension adjustments, chassis balance checks, and incremental handling refinement without changing other major components.
Installation notes: the parts are made for the TT01 family and use the same chassis attachment locations; confirm fit with your specific TT01 or TT01E variant before final installation, and retain or source any small fasteners from your existing kit or supplier as required.
