Without a driveshaft, your car doesn’t move. And that driveshaft better be be built to handle the horsepower your car puts out, because nobody wants to ride the pogo-a-gogo through the finish line at the racetrack or on the road course. The guys at Mark Williams Enterprises have been building driveshafts for the better part of 40 years, with no less than seven different styles available depending upon the needs of the particular customer.

In this video, they discuss the most important considerations to take into account when selecting a driveshaft for your application – horsepower, vehicle weight, and driveshaft length, along with critical speed of the shaft, the enthusiast’s budget, and whether the end user is looking for a lighter-weight product than what is currently in the vehicle. Each of these factors play a part in product selection. 

Perhaps most importantly, the MW facility has an on-site custom-built driveshaft test rig that is able to impart 15,000 foot-pounds of torque to a driveshaft and test a material’s capabilities to ensure it’s the proper fit for the application.

They also discuss the finer points of how to measure your car’s driveshaft length on a new build, what’s important to know about u-joints, and also some of the important points of construction for the various shaft materials. The shafts are built from end-to-end in-house in the MW facility, giving them control of the process from start to finish.
