Zumbrota Bearing & Gear Transfer Case TC4416F-1

Zumbrota Drivetrain Manual Transmissions are fully rebuilt with cases and internals thoroughly inspected for cracks, wear & tear. Zumbrota’s 3-time inspection process includes a pre-inspection for case cracks, excessive wear and to catch OEM related problems with the cores. The second inspection ensures all component parts meet OEM specification with a final inspection to ensure the unit is built to our standards. Shaft straightness, gear wear & synchronizers are extensively tested to meet OEM speciation’s. All seals are always replaced, and all units are dyno-tested for supreme operation, shiftability and noise level. Unparalleled standards are set for unit perfection and reliability at critical touchpoints. Exclusive hydro-blast rinse and sandblasting protocol on internal and external parts, followed by a proprietary shot-enticed deep cleaning, sets the unparalleled standards for these units.
