Complete Axle Assembly 3.73 Ratio

This assembly features a 3.73 gear ratio and is built for GM 7.6" Independent Front Suspension (IFS) systems. Each assembly is subjected to a comprehensive inspection process, checking for housing straightness, cracks, and surface wear. All internal components, including ring and pinion gears, clutches, and carriers, are thoroughly inspected and tested to meet high standards. Zumbrota Drivetrain replaces all bearings, seals, crush sleeves, pinion nuts, and shims. The gear tooth patterns and rolling torque are precisely measured in inch-pound increments, and the gear backlash is set correctly for optimal lubrication and quiet operation. Housings are restored to an OEM finish using advanced hydro blasting and rinsing processes. This ensures durability and a clean aesthetic. The axle assembly is shipped in high-density plastic totes to prevent damage during transit. This axle assembly is compatible with the following vehicles: Isuzu i-350 Base (2006), Isuzu i-370 4WD (2007-2008), Chevrolet Colorado models (2004-2012, specific trims and 4WD required), and GMC Canyon models (2004-2012, specific trims and 4WD required). It does not fit Denali models.
