Don’t settle for less than the best

Manufactured with all-new components

  • NOTE1: 1978-79 gearboxes include power steering hose adapters and new rag joint coupler with bolt, 1980-88 gearboxes do not.

OPGI is now offering these Delphi 600 series power steering gearboxes, which are made in America. These 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 quicker than stock or install the ultimate in quick ratio steering with the 12.7:1 ratio gearboxes. Each box comes in the 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. 3/4" - 30-spline.
