U-Joint 1in-48 Spl x 3/4in 20 Spline

The SWEET U-Joint 1in-48 Spl x 3/4in 20 Spline steering universal joint is a precision-engineered single-joint assembly designed for high-angle steering applications where shaft misalignment and articulation demand reliable power transmission. Built from steel with black paint finish, this joint bridges two different spline configurations—1 inch 48-spline input to 3/4 inch 20-spline output—making it ideal for custom steering systems where standard off-the-shelf joints do not accommodate the required geometry.

The 1-inch 48-spline connection on one end and 3/4-inch 20-spline on the other provide a compact transition between steering column shafts of different diameters and tooth counts. This configuration is common in purpose-built off-road vehicles, high-angle steering systems, and custom fabrication where OEM joints cannot achieve the required steering angles or accommodate non-standard shaft sizes. The single-joint design allows articulation while maintaining positive engagement; the spline counts and shaft diameters ensure adequate torque capacity for typical steering loads while distributing pressure evenly across the teeth.

Custom fabricators, off-road builders, and specialty vehicle technicians rely on u-joints like this when designing systems that exceed standard steering specifications—particularly in rock crawlers, ultra-high-articulation buggies, and bespoke steering linkages where shaft angles and diameters deviate from production vehicles. The steel construction and black paint provide durability and corrosion resistance sufficient for harsh field environments. Weighing 0.8 pounds and measuring 4.2 inches in length, this joint is sized for tight installation spaces without sacrificing strength or spline engagement length.
