Bring Your Rear End Back To Life Right

When your rear differential starts acting up, you can’t afford to mess around with cheap or questionable parts. The Yukon YPKGM11.5-S-30 Spider Gear Kit is a high-quality solution built for heavy-duty trucks that do real work. Whether you’re driving a 2001-2015 Silverado or Sierra HD with the 6.6L Duramax, or a 2011-2016 Dodge RAM 2500 or 3500, this kit is engineered to handle the power and torque these trucks put down. It comes complete with everything you need for a full spider gear rebuild, including side gears, pinion gears, thrust washers, a cross pin shaft, and a roll pin. These components are made from high-grade materials that hold up under stress, making it ideal for daily drivers, tow rigs, or weekend warriors. Yukon’s attention to detail and consistent quality mean this isn’t just a replacement, it’s a long-term fix you can count on. If you’re dealing with slipping, clunking, or uneven traction, this kit helps restore smooth, dependable performance where it matters most.

Built To Fit Right And Handle Real Torque

The Yukon YPKGM11.5-S-30 is designed specifically for 11.5-inch open differentials and 30-spline axles, covering a wide range of HD applications across GM and Dodge trucks. What makes this kit stand out is its ability to fit both early and late model differential cases, thanks to included adapters for small and large hub side gears. The smaller 1.816-inch hub design fits 2007-and-earlier GM trucks, while the 2.060-inch hubs are used in 2008-and-up GM models and all compatible Dodge HD applications. Yukon includes both sizes so you get a proper fit, regardless of your build year. The kit also features an early-style cross pin shaft compatible with snap ring-style carriers, offering flexibility for different carrier designs. Every component is precision-machined to ensure smooth gear engagement and quiet operation, even under heavy load. It’s a smart, factory-style solution with the strength to keep your truck moving forward reliably.
