This lets the rag joint accommodate minor shifting and movement between the body and frame (or subframe) and provides vibration damping to keep the steering wheel from jumping around.
Copydex Joint Master Manual Steering IsBut there are instances where manual steering is better than a power setup.Copydex Joint Master Free Up AFor example, manual steering on a drag race car will save weight and free up a couple horsepower (no power steering pump to turn). Cars with engine swaps in tight engine compartments (think street rods with V8s) are also candidates for manual steering. For vintage iron like Camaros, Novas, Chevelles, and Mustangs, you can still find manual steering setups at swap meets or from aftermarket sources like Summit Racing. Borgeson manufactures power to manual conversion kits for these cars. Summit Racing offers the Borgeson kits and the necessary small parts to complete the conversion. GM used this cast iron box beginning in the 1950s and installed it on 60s muscle cars. It was available with a 24:1 or a quick feel 16:1 steering ratio and a 34-inch diameter, 30-spline input shaft. Even though its beefy, the 525 box shaves approximately 28 pounds of weight compared to a factory power system. Three bolts hold the steering box to the vehicle framejust unbolt the power box and bolt on the 525 box. Youll have to replace the pitman ar, and swap the rag joint for certain applications, but no fabrication is required. When youre done, that mess of hoses, fluid reservoir, bulky power steering pump, and power steering box are gone, replaced by a clean, simple steering system. Its far beefierand isnt much biggerthan the Vega manual box that is commonly used in steering swaps. ![]() This is a brand new, 24:1 ratio 525 steering box from the Borgeson manual to power steering kit, available at Summit Racing. At three-quarters of an inch in diameter, the 30-spline input shaft is nice and beefy. Heres a before of the 1986 Buick Regal T-Type with the engine, power steering pump, hoses, and reservoir out of the car. You can see the power steering box at the right, tucked under the mass of hose and wiring loom. The mounting bolt pattern on the Borgeson 525 box is identical to the original equipment power steering box, making it a direct swap. GM never considered the pitman arm to be a service item, so searching for the correct used one is often like searching for a needle in the proverbial haystack. If you need a different pitman arm for your swap, Summit Racing has Borgeson arms in stock. Installation is the same as a stock OEM partline up the splines and the indexing flat and tighten. A flexible joint (more commonly called a rag joint) connects the steering column to the steering box. It provides a small amount of flex between the steering column shaft and the steering box input shaft, and allows for a minute amount of misalignment between the two.
