If you want an easy way to upgrade the handling on your classic Chevy, have you ever considered a quick-ratio steering box? Maybe you have factory-installed power steering and didn’t realize a quick-ratio upgrade was possible. Thanks to Borgeson Street & Performance, it is an option.
Traditional power-assisted steering gearboxes were originally manufactured with a wide (slow) turn ratio. Most units delivered a variable ratio, typically around 16:1. Putting that into perspective, the steering wheel would rotate a full four to five turns from lock-to-lock. These units also incorporated variable pressure, meaning they would exhibit a slow steering response near the center point, but a quicker response as you approach the ends of their maximum range.
The most popular gearbox used in most ‘60s and ‘70s GM cars was the Saginaw 800 box. If you wanted to improve the steering ratio in your car, you needed to swap in a non-power-assisted gearbox. But now, that requirement is a thing of the past.
Borgeson just told us that it offers an all-new, modern, quick-ratio power steering box to replace the Saginaw/Delphi 800 series in most 1965 and up GM muscle cars. “We developed the box with one of our current manufacturing partners, and we assemble and test them in the USA,” said Jeff Grantmeyer of Borgeson.
This all-new steering box has a quick 12.7:1 ratio, and delivers a firm, modern, steering feel. The Borgeson Street & Performance power steering box will bolt directly to the stock location and fit original power steering pitman arms. Cars switching from manual steering, however, will require a power steering pitman arm. The steering box includes adapters, so you can use either O-ring or flare-style hose connections. This new Borgeson steering box uses a 3/4-inch by 30 spline input shaft, and all pre-1977 cars will require a new rag joint connector (#990012).
