Description
When you swap to a TREMEC or other high-performance transmission with a 31-spline output, your stock driveshaft becomes obsolete. This custom aluminum driveshaft delivers the perfect combination of weight savings, strength, and precise fitment that a serious drivetrain upgrade demands. The 4.0-inch diameter aluminum tube provides exceptional torsional rigidity while the larger tube diameter allows for longer single-piece driveshaft lengths - eliminating heavy, failure-prone two-piece setups in many applications.
The billet steel slip yoke is machined for 31-spline transmission outputs, ensuring a precision fit with TREMEC TKX, TKO, T56 Magnum, and other modern performance transmissions. 1350 series U-joints deliver roughly 37% more torque capacity than the 1310 series joints found in most factory applications, making this driveshaft well-suited for high-horsepower builds under 1,200 hp. The stronger joints and upgraded yoke hardware throughout mean your driveline can handle the increased torque without becoming the weak link.
Aluminum construction offers significant advantages beyond just weight savings. The reduced rotating mass means less parasitic power loss accelerating the driveshaft, translating to quicker acceleration and improved throttle response. The brushed aluminum finish also looks the part under a show car or street machine. Every driveshaft is professionally assembled and high-speed balanced to eliminate vibration at all operating speeds.
Because every vehicle's dimensions are unique, this driveshaft is custom-built to your specifications. After ordering, you'll complete our driveshaft build sheet with the measurements from your finished vehicle and submit it to start the fabrication process. Custom lengths up to 58 inches are available. Made in the USA with lifetime technical support to ensure proper fitment and performance.
