Description
Your classic Mustang's factory steel driveshaft is heavy, rust-prone, and adds unnecessary rotating mass to your drivetrain. Switching to aluminum typically saves 10-20 pounds, but the real advantage is reduced rotational inertia—that weight reduction translates to improved throttle response, quicker acceleration, and less strain on your engine. Because aluminum can be made thicker without penalty, it delivers better balance and higher critical speed than comparable steel shafts.
This MDL aluminum driveshaft features a robust 3.5" diameter tube paired with a 31-spline forged steel slip yoke for solid transmission engagement. The 1310 series u-joints handle 400 lb-ft of continuous torque and 800 lb-ft short duration—more than adequate for most street and moderate performance builds. The 50" length is sized specifically for 1965-1973 Mustang applications.
Unlike steel, aluminum is naturally resistant to rust, giving your driveshaft longer service life in wet or snowy conditions. Each driveshaft is custom-built to your specific measurements using our driveshaft build sheet, ensuring perfect fitment and eliminating the vibration issues that plague one-size-fits-all solutions. Simply submit your completed build sheet to info@moderndriveline.com to start the process.
Whether you're building a weekend cruiser or a performance driver, this aluminum driveshaft delivers measurable improvements in drivetrain efficiency. Made in the USA with professional craftsmanship and backed by lifetime technical support.
