You are probably asking what is a Flow Formed Wheel. Flow Formed wheels are wheels that have been made by applying pressure to the inner barrel of the wheel while it is spinning after the casting has taken place. What this does is compress and stretch the aluminum, increasing the tensile strength of the wheel. This allows the wheel to be much lighter, stronger, have a greater resistance to shock, and a higher load capacity when compared to cast wheels. The Muscle Race Wheel Flow Formed Beadlock boasts a 2,500 lb load rating. That's 1.25 tons a wheel!!! If you are a rock crawler, hill killer, or just expect your vehicle to handle all the abuse you can throw at it, these are the wheels for you.
