ACDelco GM Original Equipment Remanufactured Rack and Pinion Assemblies convert the rotation of your vehicle's steering column to the side-to-side motion needed to steer its front or rear wheels, and are GM-recommended replacements for your vehicle's original components. Remanufacturing rack and pinion assemblies is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear and failure with new components. Damaged and obsolete parts are replaced and are end of line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing helps return components back into service rather than processing as scrap or simply disposing of them. These rack and pinion assemblies will provide the same performance, durability, and service life you expect from ACDelco.
