Product Details

This Yukon Gear & Axle pinion yoke is built for GM 12-bolt rear differentials found in a wide range of passenger cars and trucks, including the 1963-1974 Chevrolet Corvette. It's designed to work with a 1310 series universal joint, which is a common size for many GM applications. If you're replacing a worn-out yoke or building a new rear end, this part offers a well-built solution.

You'll receive the yoke itself, ready to be installed. It features an outside snap ring design with a 3.219-inch span and a 1.062-inch cap diameter, ensuring it mates correctly with compatible U-joints. The strap style mounting means you'll use straps and bolts to secure the U-joint caps, a straightforward method for many builds. This yoke has 30 splines, matching the output shaft of many GM 12-bolt differentials.

Yukon Gear & Axle is known for making a broad selection of replacement and performance driveline parts. This yoke is a good choice for general replacement needs on street-driven vehicles, and it's also suitable for racing or heavy-duty off-road use, depending on the rest of your driveline setup.
