Wing, Revo (black)/ decal sheet The Traxxas Revo wing and wing mount are the latest additions to the performance accessory line-up for the six-time National Champion Revo 3.3. The combination of the adjustable deflection angle, wing height, and the unique wing design allow tuning options for any track condition and driving style. The wing mount kit includes the mount, hardware, and installation instructions. The wing is available separately in white, black, or the new Exo-Carbon finish. Traxxas offers a wide variety of spring rates for the GTR shocks to precisely compensate for lighter or heavier truck configurations. The springs use high-quality spring steel with durable powder-coated finishes. Spring rate is indicated by colored dots on the end of the spring.
