Kyosho UBW009 - RB7.5/ZX7.5 Carbon Rear Suspension Arm  [KY-UBW009]

Carbon rear suspension arm compatible with RB7.5 and ZX7.5

This carbon composite rear suspension arm is compatible with RB7.5 and ZX7.5 chassis and functions as a direct replacement or hop-up item. It affects rear suspension geometry and load transfer while not requiring changes to driveline components.

Made from the carbon composite described in the product name, the arm provides focused stiffness and a reduction in component mass compared to many polymer parts. It is intended as a spare or upgrade piece to fit in the same location as the original rear suspension arm on RB7.5 and ZX7.5 platforms.

Installation guidance: remove the wheel and detach the rear hub as necessary, reuse existing pins and fasteners if no hardware is listed, use suitable hex drivers for assembly and confirm bearings and hub clearance after mounting. View the change as a geometry update—inspect camber, toe and ride height and adjust dampers and links in small steps to dial in handling.

Provided as a carbon composite rear arm for RB7.5 and ZX7.5 chassis, this part is aimed at suspension servicing and setup refinement rather than a full upgrade bundle.
