Kyosho UBW008 Carbon Composite Front Suspension Arm (RB7.5)  [KY-UBW008]

Front suspension arm for RB7.5

This Kyosho UBW008 front suspension arm is an RC-scale replacement part manufactured in carbon composite, intended for use on assemblies identified with the RB7.5 designation. It is presented as a direct swap candidate for front-end suspension setups where RB7.5 components are specified, serving the functional role of restoring geometry or supporting tuning changes without implying fitment beyond the RB7.5 context.

As a suspension link, the arm affects static geometry and transient response. When replacing stock arms, confirm that hinge-pin locations, mounting bosses, and track width match your chassis before installation. Small differences in arm length or mounting hole location will alter camber and steering behaviour, so treat this part as a geometry element rather than a plug‑and‑play performance modifier.

Installation follows standard front-arm replacement steps: remove the wheel and upright as needed, detach the existing arm at the hinge and steering blocks, transfer any inserts or pins to the new arm if required, then reassemble and check free movement through the suspension travel. After installation, verify wheel alignment and wheel bearing seating and perform slow checks for binding through the full suspension range.

For setup and tuning, use the arm to make measured changes to static camber and toe rather than large, untested jumps. Inspect the arm periodically for wear at mounting points and for secure fasteners after a few runs. Because the material is carbon composite, avoid overtightening fasteners at the mount interfaces to prevent local crushing of any bonded or layered sections.
