Description
Your classic Cougar deserves better than worn-out original equipment. This custom steel driveshaft solves the vibration, balance, and durability problems that plague stock driveshafts in restored and performance Cougars. Built from 3-inch drawn over mandrel (DOM) steel tubing, this driveshaft delivers 15% more strength than OEM tubing while maintaining tighter tolerances for easier balancing and smoother operation.
The engineering advantage of DOM tubing comes from the cold-drawing process that pulls the tube through dies and over a precision mandrel. This manufacturing method produces superior concentricity, uniform wall thickness, and enhanced tensile strength compared to standard welded seam tubing - critical factors that eliminate the balance issues and structural weak points found in factory driveshafts. The result is a driveshaft that spins true and handles power without drama.
The forged steel 28-spline slip yoke provides bulletproof engagement with your transmission output shaft, while 1310 series U-joints handle power transfer with proven reliability. Every driveshaft is professionally high-speed balanced to eliminate vibration and extend component life. The black paint finish protects against corrosion while maintaining the understated appearance your restoration demands.
This driveshaft is application-specific for 1967-1973 Mercury Cougar Non Hi-Po V8 models with a 51.25-inch length. Because every build is different, MDL requires a completed driveshaft build sheet with your specific measurements before manufacturing. Submit your completed form to info@moderndriveline.com.
