Tri & Quad Prongs

Tri and quad prong yokes serve specific flange connection applications where a standard round flange configuration doesn’t fit the companion flange geometry or isn’t the correct design for the drivetrain in question. Three-bolt and four-bolt prong yokes are common in import vehicles, older domestic applications, and certain industrial drivetrains where the original engineers chose this style of connection for packaging or torque distribution reasons. Getting the right prong yoke means matching the bolt circle diameter, the prong width, the U-joint series, and the overall yoke style — all of which vary significantly between applications. Our tri and quad prong selection covers the most common fitments, and our team can help you cross-reference the correct part when the application is unusual or difficult to identify.
