Description
When you've upgraded your S550 Mustang to a TREMEC Magnum XL 6-speed rated for 700 lb-ft of torque, your factory driveshaft becomes a liability. This custom aluminum driveshaft solves that problem with a purpose-built design that matches the Magnum XL's 31-spline output shaft while delivering the strength and weight savings your performance build demands.
Built around a 3.5-inch diameter aluminum tube with .125-inch wall thickness, this driveshaft strikes the optimal balance between rigidity and rotating mass reduction. Aluminum construction significantly reduces weight compared to steel, improving throttle response, reducing drivetrain stress, and freeing up horsepower that would otherwise spin unnecessary mass. The billet steel slip yoke ensures a rock-solid connection to the transmission's 31-spline output, while 1350 series U-joints provide the strength needed for high-torque applications.
Every driveshaft is custom-manufactured to your vehicle's exact specifications. After ordering, you'll submit measurements using our driveshaft build sheet to ensure perfect length, proper phasing, and correct operating angles for your specific combination. The 113mm manual pinion flange provides a direct, secure bolt-up to your Mustang's IRS differential. Professional balancing and precision manufacturing ensure smooth, vibration-free operation from idle to redline.
Designed for 2015-2025 Mustang 5.0L applications equipped with TREMEC Magnum XL transmissions. Made in the USA with premium materials and backed by MDL's technical expertise and lifetime tech support.
