Our 180° Quarter-Max driveshaft is constructed of 1" .065 4130 tubing. At RJ Race Cars, Inc and Quarter-Max we make all of our Driveshaft Loops and Driveshaft Tunnels out of 4130.
While some of our competitors are using mild steel to save money. We are looking out for your safety and we only build our product out of the best materials available. Can you put a price on safety?
