Drag Racing Driveshaft selection is influenced by many factors. Because every application is different, choosing the right drag racing driveshaft requires that you examine the requirements of each application. These few factors are essential to ensure reliability and the best performance.
Strength
First, consider the drag racing driveshaft strength that a racer will require. The driveshaft must be strong enough to withstand the extra power and weight of a car. When choosing a driveshaft, one important factor to consider is the car's weight. You can also look for the best drag racing driveshaft online.

And no matter what material, increasing the diameter of a driveshaft will increase its strength. Increase the diameter of a driveshaft from 3" to 4 inches will increase its strength by around 80%. We will also discuss other benefits of increasing diameter later.
Drag racing uses the 1350 and 1480 series of u-joints. Both are offered by M-W. They provide the best combination of strength, precision, and weight. They can be used in all classes, from pro-stock to professional.
1480 joints are reserved to be used for heavy-duty applications. They are mainly used in Pro Mod and other high-power classes, especially when tire shaking is a problem. U-joints are often the weakest part of the system.
Critical Speed
Critical speed refers to a situation in which the natural frequency and the rotation speed of the driveshaft are equal. These coincide vibrations will multiply and eventually cause the driveshaft to fail. It is crucial to ensure that your car can operate at speeds below the critical speed when considering a driveshaft.
