Fioroni's Ultra Racing Series parts for the Associated RC8 series feature original designs and concepts, and are produced for the highest level of racing. We have received positive feedback particularly for the new aluminum diff housings, chassis braces, and of course Fioroni's famous chassis plates. Many of these parts will also fit the 8B, 8T, SC8, SC8E, RC8E, RC8TE, and the new RC8.2.

   
   

Associated RC8 Hardened & Ultra Light 3mm Main Chassis

Made of ergal 3mm aluminum the Fioroni RC8 chassis comes hard anodized for long wear and milled for light weight. Grooves under the gearboxes allow the installation of the supplied o-ring to form a dirt tight seal. The 'OT' Option Team logo is milled on top and laser engraved underneath for improved appearance. Steel droop stops come pressed into the chassis to prevent the droop screws from causing damage.
