OPGI is now offering these Delphi 600 series power steering gearboxes, which are made in America. Gearboxes are a direct bolt-in replacement for typically worn-out, sloppy original gearboxes. Manufactured with new components inside and out, these boxes use the latest in steering technology including a rack and pinion-style servo. Designed to provide quick response and precise control throughout the steering range, these gearboxes will add a very modern feel to any classic. Two gear ratios are available to suit your needs. Choose from the 14:1 ratio, which is greater than stock or install the ultimate in quick ratio steering with the 12.7:1 ratio gearbox. Each box comes in standard raw form or with a special "Trivalent" coating, which adds protection and good looks. No matter which box you choose, it will surely enhance your driving experience.
