It's designed for enhanced performance, offering stronger traction, higher speeds, and increased towing capabilities. The assembly includes high-quality nodular steel ZPA differential covers for strength and protection. All components are inspected, and bearings and seals are replaced during the remanufacturing process. It undergoes a hydro-blast rinse and sandblasting procedure for deep cleaning.
