Features and Benefits
New BorgWarner chain installed in every unit — the same OE-supplier chain trusted by GM — ensures smooth, reliable 4WD power transfer and eliminates the stretch and wear that plagues high-mileage rebuilt units.
OE-grade Timken and Koyo bearings replace worn originals, matching the same bearing brands used in GM factory drivetrain assembly for precise fit and long-term durability.
Upgraded heavy-duty aluminum housing replaces weaker OEM magnesium cases where applicable, correcting a known design limitation and improving structural integrity for demanding work-truck applications.
100% inspection of all internal components ensures no worn, cracked, or out-of-spec parts make it into the finished unit — every transfer case leaves the facility fully validated.
3-step spin testing on every unit verifies proper engagement, shift function, and internal operation before shipment — so you install with confidence, not guesswork.
Manufactured in the United States and backed by a 3-year/36,000-mile warranty — delivering the coverage and accountability that heavy-duty drivetrain work demands.
Brand: US Powertrain
