NV246 Remanufactured Electric Shift Transfer Case — Aluminum/Magnesium Housing, Chain Drive, for 2003–2007 Chevy/GMC 4WD Trucks & SUVs

When your GM truck or SUV's transfer case fails, trust the drivetrain specialists at US Powertrain to deliver a remanufactured NV246 that goes further than simply restoring original function. The US Powertrain 412.137-5 is a fully remanufactured NV246 electric shift transfer case engineered for 2003-2007 Chevrolet and GMC 4WD light-duty trucks and SUVs — including Silverado, Sierra, Suburban, Avalanche, and Yukon XL applications. Every unit is built with a new OEM-spec BorgWarner drive chain, premium OE-grade Timken and Koyo bearings, and where applicable, an upgraded aluminum housing in place of the factory magnesium case — a proven improvement that addresses a known OEM design weakness. Rather than simply cleaning and reusing serviceable internal components, US Powertrain applies a 100% internal parts inspection protocol followed by a rigorous three-step spin test on every unit before it leaves the facility. This means each transfer case is validated for proper engagement, output balance, and leak-free operation — not just assembled and shipped. Manufactured in the United States and backed by a 3-year/36,000-mile warranty, this transfer case is the professional-grade choice for repair shops and fleet operators who cannot afford a comeback. Note: mounting hardware is not included.

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 Chevrolet/GMC 4WD Trucks & SUVs - 3-Year/36K-Mile Warranty

New OEM-spec BorgWarner drive chain replaces the worn factory chain, restoring precise 4WD engagement and eliminating chain slap noise at the root cause.

Upgraded aluminum housing replaces the factory magnesium case where applicable, correcting a known OEM design vulnerability and improving long-term structural durability.

OE-grade Timken and Koyo bearings used exclusively throughout — the same bearing brands specified by GM — ensuring proper load ratings, fit, and service life.

100% internal parts inspection on every unit eliminates the guesswork of variable-condition cores, so every transfer case ships with fully validated internals.

Three-step spin testing performed on every finished unit verifies proper gear engagement, shaft balance, and leak-free sealing before shipment — not a sample test, every unit.

Manufactured in the United States and backed by a 3-year/36,000-mile warranty, providing professional-grade confidence for repair shops and fleet operators.
