This listing covers a remanufactured 11.5-inch rear differential for 2011-2017 GMC Sierra 3500 applications. This unit can be configured with a 3.73 or 4.10 gear ratio to match your vehicle's original spec. Rebuilt to spec in-house, this unit ships with our 3-Year Warranty — axles, hubs, and backing plates are included. Bolt it straight into your drivetrain, top off the fluids, and you're back on the road. This rear differential fits GMC Sierra 3500 models from 2011-2017. We're based in Pueblo, Colorado, with over 34 years of experience rebuilding and remanufacturing GMC drivetrain components. A lot of online sellers just drop-ship; we actually rebuild and inspect every unit ourselves. Call us if you need a different gear ratio; we also build custom differentials from scratch. Core charge policy: as long as you schedule your core for pickup within 30 days of your purchase date, there's no upfront core charge. If you select the option to waive the core charge, you're authorizing us to bill your card for that amount if the core isn't returned within the 30-day window, and your warranty will be voided if the core isn't returned or paid for. We cover return shipping at no cost to you. Cores need to be in acceptable condition (no cracked housings, bent tubes, etc.); call us at 719-460-7267 if you have questions.
