These steering joints, also known as U-joints or universal joints, are essential components for connecting and transmitting rotational motion between two shafts that are not perfectly aligned. With a 11/16-36 spline on one end and a 3/4 inch double-D (DD) on the other, these joints allow for smooth and efficient power transfer while accommodating the varying angles between the shafts. Commonly used in steering systems, driveshafts, and other automotive applications, these U-joints are designed to handle the rigors of constant movement and vibration. Constructed with durable materials and precision engineering, they ensure reliable performance and longevity. Whether you're working on a restoration project or replacing worn-out components, these steering joints are a must-have for maintaining the proper operation of your vehicle's steering and drivetrain systems.
