Rear Remanufactured Locking Differential — GM 10.5" 14-Bolt 4.10 Ratio | 2019–2025 Chevy Express 3500 & GMC Savana 3500

When a rear differential fails on a heavy-duty commercial van, the consequences extend well beyond inconvenience — for a working fleet vehicle, downtime means lost productivity, emergency towing, and costly repairs that disrupt operations. The US Powertrain Remanufactured Rear Differential is a direct-fit solution engineered to restore these full-size vans to full service with confidence. Built around the robust GM 10.5" 14-bolt axle platform with a 3.73 gear ratio, this unit is purpose-built for the demanding payload and towing duties the Chevrolet Express 3500 and GMC Savana 3500 are engineered to handle. US Powertrain goes beyond standard remanufacturing. Every unit undergoes thorough housing inspection, professional cleaning, and a blast-and-coat process that produces an OEM-matching black finish. Internal components that fail to meet original equipment specifications are replaced — not reused — with new OE-quality seals, gaskets, and premium bearings from trusted suppliers including Timken and Koyo. The differential cover is included, delivering a complete, ready-to-install assembly that eliminates the need to source additional components before the job begins. Backed by a 2-year / 36,000-mile manufacturer warranty and proudly manufactured in the United States, this unit is the smart, accountable choice for professional installers and fleet operators who cannot afford a shortcut.
