With today’s incessant need for more power comes the necessity to strengthen components to handle the extra power, and that’s where Mark Williams Enterprises steps in for the racer and enthusiast. Showing us some of his latest products at the Performance Racing Industry trade show in Indianapolis this month, Williams pointed out that there were some inherent problems when combining the Mustang GT500’s driveshaft with high horsepower applications.

“The new 2014 and 2015 Mustangs have a two piece carbon fiber driveshaft with CV joints; it’s a really nice piece but it’s just not strong enough,” Williams said. So what they came up with was a new 7075 billet aluminum slip joint driveshaft for the Mustang that is much stronger than the original driveshaft.

The problem with making a one piece driveshaft is that the Mustang’s transmission has a rigid flange instead of a slip yoke. The one-piece driveshaft requires a slip joint to provide the necessary plunge as the suspension moves.

The shaft was originally designed for Carroll Shelby, and although it has been used in a few high-horsepower applications it was designed for the Mustang GT500. They utilized bonded technology instead of welding the flange for a stronger bond between flange and shaft. Williams also showed us a new yoke in both steel and aluminum for a 35-spline 9-inch differential that accepts the stronger 1350 universal joint.

Also on display was their 40-spline drive plate and floater axles for truck, circle track, rock crawlers and other heavy duty applications. Applications also include the wide five hub in the circle track market. Available in 4340 or 300M steel. They’re heat treated and black oxide coated for strength and durability, with the 300M steel used for high stress applications.
