Description
When you swap a TREMEC T56 Magnum six-speed into your Fox Body Mustang, the factory steel driveshaft becomes a liability. That heavy stock shaft robs power through rotational mass while potentially limiting the Magnum's 700 lb-ft torque capacity. This custom aluminum driveshaft solves both problems - dropping significant weight while delivering the strength your upgraded drivetrain demands.
A high-quality driveshaft plays a critical role in any performance vehicle. Your car needs a shaft that can withstand intense conditions, stresses, and high RPM without adding unnecessary weight. The 3.5" aluminum tube provides excellent torsional rigidity at a fraction of the weight of steel. The forged steel slip yoke delivers durability at the critical transmission connection point, with a 31-spline configuration that matches the Magnum's output shaft precisely. At the rear, the 8.8" flange bolts directly to Ford's popular differential.
The 1330 series U-joints handle torque transfer with proven reliability - featuring 1.062" cap diameter and 3-5/8" overall width. This series has been Ford's standard for performance applications since the late 1970s, offering an excellent balance of strength and driveline angle capability.
Each driveshaft is professionally built to your exact measurements after you've completed your transmission installation. This build-to-order approach ensures perfect length, eliminates vibration issues, and provides optimal driveline angles for smooth operation. Simply complete the MDL Driveshaft Build Sheet with your measurements and submit it to begin fabrication. Whether you're building a street cruiser or a weekend track car, this aluminum driveshaft delivers the lightweight strength your Fox Body T56 Magnum swap deserves. Fits 1979-1993 Ford Mustang with T56 Magnum transmission and 8.8" rear differential. Made in the USA.
