Custom Driveshaft & Slip Yoke - 4" Al. 3R, GM 32 Spline (Short) (Sku: 4A3R-P(short))

Exceeding Industry Standards

Quality Aluminum Driveshafts


When you need a driveshaft that is lightweight, can handle higher torque loads and can give you a nice polish finish, then consider an Action Machine aluminum driveshaft. The Action Machine aluminum driveshaft is ideally suited for street rods, show cars, race cars and as OEM aluminum replacements. While other driveline shops may use .065" wall or .083" wall tubing for their aluminum driveshafts, our volume purchasing allows us to use .125" wall tube for the same price as the thinner tube. You have the best in aluminum performance no matter your application.
