The ARRMA KRATON 8S Aluminum Rear Wheelie and Wing Mount by GPM MAKX040R is CNC inspired in design and focused on repeatable performance. Machined aluminium construction enhances structural stiffness and resistance to wear, while the adjustable wing and wheelie angle options allow precise setup tuning to match track conditions. Handmade Delrin wheels supplied with installed bearings reduce rolling resistance and deliver consistent rotational behaviour under load.
