We consider a Hot Rod any vehicle which is built for fun, not specifically designed for racing. There are many variations on the requirements for Driveshafts for Hot Rod applications. Filling out the information form on our Orders page will help us guide you in the right direction. The U-Joint series will usually not affect the price of the shaft. In our Driveshafts 101 section, you will find information for the most common U-joints for identification.
