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

Carbon composite rear arm suited to RB7.5/ZX7.5

This carbon composite rear suspension arm is designed specifically for RB7.5 and ZX7.5 chassis configurations. It replaces the standard rear arm and changes rear suspension geometry and load behaviour without modifying the drive train components.

Constructed from the carbon composite stated in the product name, the arm gives localized stiffness and weight reduction compared with some plastic parts. It is supplied as a spare or hop-up for hobbyists to fit where the original rear suspension arm sits on RB7.5 and ZX7.5 chassis.

Installation advice: take off the rear wheel and separate the hub as necessary, keep or reuse current pins and screws unless extra hardware is listed by the seller, use the appropriate hex bits for fasteners and check that suspension and hub bearings move freely and align correctly after mounting. For setup, treat this as a geometry change and adjust dampers, toe and camber incrementally.

Offered as a carbon composite rear arm for RB7.5 and ZX7.5 chassis, this part supports suspension servicing and fine tuning rather than being a comprehensive upgrade package.
