Chevrolet Silverado 3500 Rear Differential 11.5-Inch 1999-2006

We're proud to offer this remanufactured 11.5-inch rear differential for the 1999-2006 Chevrolet Silverado 3500. 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. Confirmed fitment: Chevrolet Silverado 3500, 1999-2006. We're based in Pueblo, Colorado, with over 34 years of experience rebuilding and remanufacturing Chevrolet drivetrain components. Call us if you need a different gear ratio; we also build custom differentials from scratch. Core charge policy: schedule your old core for pickup within 30 days of purchase and you won't be charged anything upfront. Choosing to waive the core charge authorizes us to charge your card for the core amount if it isn't sent back within that 30-day period, and not returning or paying for the core will void your warranty. Return shipping is on us. Cores must come back in acceptable shape (no cracked housings, bent tubes, etc.), so call 719-460-7267 if you're unsure.
