GM CLASSIC CAR 12:1
GM CLASSIC CAR, Saginaw 800 Gearbox, 3 bolt, 12:1, 35# valve
Quick ratio OEM replacement steering gearbox.
This is a newer style Saginaw 800 gearbox that has the smaller 3/4-30 spline input shaft. If you are installing in a Pre 1980 vehicle, you will need a 3/4-30 rag joint (our Part # 62710-S), or you can choose to the 13/16-36 input shaft upgrade for $45. Also choose the fitting style that matches your needs (Seat kit installed for Pre 1980 inverted flare hoses, No seats installed for 1980- Present o-ring style hoses, or -6 AN fittings).
This gearbox is fitted with a custom 35# valve that will give your classic car that modern car feel you are looking for. This is the most popular gearbox we sell! To lean more about steering feel and valve weights take a look at this link:Steering Feel Explained
