Zumbrota NP261 Transfer Case | 2001-2007 GM Duramax 6.6L

When you buy a Zumbrota transfer case, you gain the confidence, satisfaction, and peace of mind that comes with our standard 2 year, unlimited mileage warranty. Zumbrota transfer cases are rebuilt to unparalleled standards. All units are restored to like-new condition by craftsmen with over 150 years of combined industry experience. Cases and internal components are inspected and tested for signs of wear like cracks, stripped threads, shaft warp, gear wear, and chain stretch. Each unit is fully rebuilt with replacement of all bearings, seals, and viscous couplers. Zumbrota uses an exclusive hydro-blast rinse and sandblasting procedure on internal and external parts, followed by a proprietary shot-enticed deep cleaning. All finished units are thoroughly spin tested for shiftability and noise. All transfer cases are shipped in high density plastic totes to eliminate damage in transit.
