DISC BRAKE ROTR ONLY

Zumbrota Drivetrain Axle Assemblies are rebuilt to the highest quality standards of precision and reliability. Each axle assembly is thoroughly inspected for straightness, cracks, and surface wear. All internal components, including ring & pinions, internal gears, clutches, and carriers, are fully inspected and tested. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced. Gears are fully inspected for optimal tooth contact patterns and correct rolling torque using inch-pound measurements for precise setup and longevity. Correct gear backlash is set to ensure proper gear lubrication and quiet operation. Axle tubes are inspected to ensure OEM standards of straightness. Zumbrota uses an exclusive hydro-blast rinse and sandblasting procedure on internal and external parts, followed by a proprietary shot-enticed deep cleaning, setting the standard for axle assembly remanufacturing. This specific assembly features a Posi LSD.
