Description
Eliminate unnecessary rotating mass without sacrificing strength. This custom aluminum driveshaft replaces heavy steel units with a lightweight 3.5-inch aluminum tube assembly, delivering real weight savings where it matters most—at the drivetrain. Whether you are building a street machine that needs to hook on the street or a race car where every pound counts, aluminum construction provides the performance advantage that steel simply cannot match.
The 31-spline 4140 billet steel slip yoke ensures bulletproof engagement with your transmission output shaft, handling high-torque launches without concern. The 1350 series U-joints provide approximately 37.5% more torque capacity than the common 1310 series, making them the preferred choice for performance applications exceeding 400 horsepower. Every driveshaft is professionally high-speed balanced to eliminate vibration throughout the full RPM range.
This is a fully custom-built driveshaft—not an off-the-shelf unit. You will need to complete the Driveshaft Build Sheet with your exact vehicle measurements after the chassis and drivetrain are finalized. This ensures proper length, yoke fitment, and phasing for your specific application. Ideal for street rods, show cars, race cars, and performance builds up to 700 horsepower at lengths up to 58 inches. Made in the USA with lifetime technical support included.
