Drive Shaft Flange Yoke

What Is a Drive Shaft Flange Yoke?

The drive shaft flange yoke is one of the most fundamental — yet often overlooked — components in your vehicle's driveline system. A flange yoke connects the driveshaft to the transmission, transfer case, or differential using a bolted flange interface, creating the secure mechanical bridge that allows rotational power from the engine to reach the drive wheels. Without a properly functioning flange yoke, that transfer of torque breaks down entirely.

Unlike slip yokes or end yokes, which thread or press onto a shaft, a flange yoke bolts directly to a companion flange on the drivetrain component it mates with. This design is common on rear axles, transfer case outputs, and heavy-duty truck applications where a secure, high-torque connection is essential. Flange yokes are available in both standard single U-joint styles and double cardan constant velocity (CV) configurations, the latter being especially popular for lifted trucks and off-road vehicles that require greater driveshaft operating angles.

Why the Right Flange Yoke Matters

Choosing the correct flange yoke is critical for fit and performance. Key specifications to match include the U-joint series (such as 1310, 1330, 1350, or 1410), the bolt circle diameter, the pilot diameter and type (male or female), and the bolt hole pattern. A mismatched yoke can cause vibration, premature U-joint wear, and in severe cases, driveshaft failure. Flange yokes are also available in aluminum for weight-sensitive, high-performance applications where rotational mass reduction is a priority.

Common applications span a wide range of vehicles — from cars and light trucks like Ford, Chevrolet, GMC, Jeep, and Dodge, to heavy trucks and off-road equipment. Whether you're doing a straight OEM replacement after wear or corrosion, converting from a standard to a CV driveshaft configuration, or building a custom driveline, there's a flange yoke designed for the task.
