Product Description

The Yukon YY GM15579602 is a direct-fit replacement pinion yoke for the GM 9.5" 14-bolt rear differential, covering an extensive range of Chevrolet and GMC 1/2-ton and 3/4-ton trucks, SUVs, and vans from the late 1970s through 2013. Engineered with a 30-spline interface and 1350 U-joint sizing, this yoke connects the driveshaft to the rear differential pinion with factory-equivalent precision. The outside snap ring design simplifies U-joint installation and future servicing without specialty tools.

Built from steel and manufactured in the USA, this yoke is rated for street, towing, and heavy-duty off-road use. It replaces worn, loose, or damaged OEM yokes that can cause driveline vibration, clunking, or premature U-joint failure. The 3.625-inch snap ring span and 1.188-inch cap diameter match the factory GM 9.5" specification exactly, making this a true bolt-in replacement requiring no modification.

Buyers should verify their specific U-joint series and snap ring style before ordering. Vehicles using the 1350 outside snap ring configuration on the GM 9.5" are the correct application for this yoke. For 1998-and-newer trucks with a triple lip seal design, or 2010-and-newer applications using a 1415 U-joint, alternative Yukon yoke part numbers apply. GM strap hardware (GM3920486) is required for installation and sold separately. All Yukon yokes carry a 1-year warranty against manufacturing defects.
