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

Carbon rear arm for RB7.5 and ZX7.5

This RC-scale carbon composite rear suspension arm is made for RB7.5 and ZX7.5 chassis layouts. It serves as a direct replacement or upgraded structural arm that influences rear suspension geometry, load transfer and tuning without changing other drivetrain parts.

The component uses carbon composite material as stated in the product name, delivering targeted stiffness and a weight saving compared with some polymer alternatives. It is offered as a spare or hop-up item for hobby use, to be fitted where the original rear suspension arm locates on RB7.5 and ZX7.5 designs.

Installation notes: remove the wheel and disconnect the rear hub as required, retain or reuse the existing pins and fasteners unless the seller lists included hardware, use the correct hex driver for screws and confirm alignment and free movement of the suspension and hub bearings after fitting. During setup tuning, treat the arm as a geometry change—verify ride height, camber and toe after installation and make small adjustments to dampers and linkages to regain the desired handling.

This item is presented as a carbon composite rear arm for RB7.5 and ZX7.5 RC chassis, intended for suspension maintenance and tuning rather than a standalone upgrade kit.
