NV246 Remanufactured Electric Shift Transfer Case — 2003–2007 Chevy/GMC 1500 4WD Silverado Sierra Tahoe Yukon Suburban Avalanche

When your GM truck or SUV's four-wheel-drive system stops performing reliably, you need a transfer case replacement you can count on for the long haul. The US Powertrain Remanufactured NV246 Electric Shift Transfer Case is built to restore confident 4WD operation to 2003-2007 Chevrolet and GMC 1500-series trucks and SUVs — including the Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, and their variants. Every unit goes through a comprehensive remanufacturing process engineered to address not just wear, but the known design limitations of the original equipment. US Powertrain installs a new BorgWarner chain in every unit, replacing the OEM chain that is the leading cause of NV246 failure. Only OE-grade Timken and Koyo bearings are used — the same supplier-tier components found in original GM drivetrain assemblies. Where the factory used weaker magnesium housings on certain applications, US Powertrain upgrades to heavy-duty aluminum cases engineered for improved durability. Every internal component undergoes 100% inspection before assembly, and each completed unit passes a rigorous three-step spin test to verify performance before it ships. Made in the United States and backed by a 3-year/36,000-mile warranty, this transfer case delivers the reliability your customers expect and the margin protection your business demands.

Engineered for durability and peak performance, this part ensures reliability for your vehicle. Perfect for OEM replacement or upgrade needs

US Powertrain Remanufactured NV246 Electric Shift Transfer Case for 2003-2007 Chevy/GMC 1500 Silverado Sierra Tahoe Yukon Suburban Avalanche 4WD

New BorgWarner chain installed in every unit — directly addresses the #1 cause of NV246 failure for restored 4WD reliability from day one.

Upgraded heavy-duty aluminum cases replace the factory magnesium housing on applicable units, delivering superior structural durability under demanding 4WD use.

OE-grade Timken and Koyo bearings used exclusively — the same supplier-tier components specified by GM — ensuring long-term internal precision and smooth operation.

100% inspection of all internal components before assembly eliminates the risk of hidden wear-related defects that cause premature failure after installation.

Three-step quality-controlled spin testing on every finished unit validates performance before shipment, so you receive a transfer case that is confirmed to function correctly.

Manufactured in the United States and backed by a 3-year/36,000-mile warranty for lasting confidence in every application.
