You will find cheaper aluminum driveshafts on the internet but that is what they are – cheaper in price and quality. When you see other aluminum driveshafts with tubing that is bigger in the middle and smaller at the ends, that is a thin wall 0.075 inch aluminum which is light duty OEM material. Our 1/8 inch thick heavy duty Arconic brand tube is made with an even wall thickness and extra straight from end to end to run vibration free and for incredible torque performance. Some driveshafts with cheaper prices have conversion u-joints that step from one u-joint size to another or greaseable u-joints. Conversion and greaseable u-joints are not as strong as the cold forged solid cross u-joints that we use and have more play. Many of the cheaper shafts have cast weld yokes at each end while ours are USA made forged weld yokes. In fact, every part of our driveshaft from end to end is USA made premium product – assembled, welded and balanced by our team here in Indiana. You can’t compare the quality, durability and life you will get from our driveshaft to other lower cost driveshafts out there. This drive shaft includes the slip yoke and is balanced and ready to install.
