Description
When your transmission swap or engine upgrade demands a driveshaft that can handle serious power without the penalty of excess rotating weight, this custom aluminum driveshaft delivers exactly what performance builds require. The 3.5-inch aluminum tube construction provides an excellent balance of strength and weight reduction, while the forged steel 27-spline slip yoke ensures a reliable connection to your transmission output shaft.
Aluminum driveshaft construction significantly reduces rotating mass compared to steel, which translates to improved throttle response and less strain on your engine. Because weight is magnified when it needs to rotate, the lighter driveshaft allows your drivetrain to accelerate more efficiently. This makes aluminum an ideal upgrade for both street performance driving and weekend track duty, where every advantage counts.
The 27-spline slip yoke fits the common GM 1-3/16-inch x 27-spline output shafts found across a wide range of automatic and manual transmissions, including Powerglide, TH350, 700R4, 200-4R, 4L60, early Borg Warner T10, Muncie M20/M21 ('63-'70), and Saginaw 3- and 4-speeds. The 1330 series U-joints share the same 1.062-inch cap diameter as 1310 joints but feature a wider 3.625-inch body for increased operating angle capability, making them well-suited for vehicles with moderate suspension travel or non-factory driveline angles.
Each driveshaft is custom fabricated to your exact specifications and professionally balanced for smooth, vibration-free operation at highway speeds and beyond. Building a custom driveshaft requires precise measurements from your completed vehicle; use the provided build sheet to ensure proper fitment and optimal driveline angles. Rated for up to 650 horsepower, this driveshaft is engineered to handle spirited street driving while maintaining the refinement needed for daily use. Made in the USA.
