Team Associated ASC92548 HD CVA Bones 78.5mm

These are heavy-duty CVA (constant velocity axle) drive bones measuring 78.5mm, used in the front driveline of the Team Associated RC10B84 and RC10B84D 4WD off-road buggies to transmit power from the differential to the front wheels through the full range of suspension travel. Machined from hardened steel, they are built thicker and stronger than standard-duty bones to resist twisting, wear, and breakage under the high torque loads of aggressive acceleration, braking, and off-road impacts. The heavy-duty construction reduces driveline flex and slop, improving throttle response and keeping power delivery consistent even under hard racing conditions. These bones are a direct upgrade over the factory standard-duty CVA bones for racers who need extra durability, and also serve as a replacement for worn, rounded, or broken bones on a buggy already running the heavy-duty driveline. They are designed to work with the corresponding CVA outdrives and drive cups already fitted to the vehicle, requiring no other changes. The package includes a pair of bones, enough for one side of the front driveline.
