This performance axle assembly is designed for stronger traction, higher speeds, and heavier towing capabilities, serving as an upgrade for vehicles with larger tires, increased horsepower, or those that tow. It incorporates Yukon Gear & Axle products and is rebuilt to high standards of precision, with thorough inspections for straightness, cracks, and surface wear. All internal components, including ring & pinions, internal gears, clutches, and carriers, are inspected and tested, and all bearings and seals are replaced. Gear choices are optimized for tooth contact patterns and rolling torque, and options for positraction and lockers are available for enhanced performance. The assembly undergoes an exclusive hydro-blast rinse and sandblasting process, followed by a proprietary shot-enticed deep cleaning. Key features include a front axle assembly for GM 8.25 IFS with an open differential and a 4.88 ratio, aftermarket gear upgrades, custom options for limited-slip differentials and lockers, and high-quality nodular steel ZPA differential covers for protection. Tubes are inspected and straightened to OEM specifications, and housings are tested for surface wear and cracks.
