Welcome to our beefiest 5" x .125" seamless 6061-T6 high-performance aluminum driveshafts. Each of these driveshafts will come equiped with 1350 series NEAPCO Performance solid-cross u-joints, fully CNC'd weld yokes, and your choice of Sonnax chromoly transmission slip yoke. As always, built to order, high-speed balanced, and shipped for free.
5" Aluminum shafts for shorter length give you extremely high driveshaft critical speeds and tortional strength. The bigger 5 in. diameter also allows you to make a one-piece driveshaft up to 85 3/4" center to center of u-joint, while still giving you strength, critical speeds, and weight savings. These driveshafts come ready out of the box to hold up to 2,500+ HP. We are selective on what parts we use, and put the highest level of craftsmanship into every shaft. Drag racing driveshafts are a big part of what we do here at Full Torque Driveshafts, and we are dedicated to helping get your car down the track reliably, smoothly, and safely. Please do not hesitate to ask us any questions.
