Description
Drop serious rotating mass from your drivetrain with this custom-built aluminum driveshaft. Aluminum driveshafts typically weigh 10-20 pounds less than comparable steel units, and since that's rotating weight rather than static weight, the real-world impact on throttle response and acceleration is substantial. Less rotational inertia means your engine doesn't have to work as hard to spin the driveshaft, freeing up power that was previously wasted turning a heavier component.
Built around a 4.0" diameter aluminum tube, this driveshaft pairs lightweight construction with the strength needed for serious power. The 1350 series U-joints are rated for 2,200 lb-ft of torque capacity, making this shaft suitable for applications up to 1200hp. The forged steel 31-spline slip yoke handles high-torque loads without concern, while the larger diameter tube provides the rigidity needed for smooth, balanced operation at high RPM.
Aluminum's higher critical speed compared to steel makes it ideal for performance builds where you're pushing the rev limiter regularly. Where a steel driveshaft might begin to resonate and vibrate at high speeds, aluminum maintains stability - particularly important in longer one-piece applications. Aluminum also resists rust, giving it an edge in longevity over bare steel shafts exposed to moisture and road salt.
