SB1 Series Boxes

Turn One SB1 Series steering boxes are offered in both a universal GM fitment and an 3rd Gen F-body fitment. Our box replaces the older 1960’s-style Saginaw 700 steering boxes found on vehicles through the 1990’s. Turn One boxes are 5lbs lighter than traditional boxes and offer newer valve technology for improved steering feel and responsiveness. Our boxes are hand-built in the USA at our shop in Saginaw, Michigan. SB1 boxes are available in three steering ratios, from a stock feel to quick-ratio feel. Other customization options include your choice of stock GM fittings or AN-6 box fittings, and also come in an unplated housing and a plated version that uses a corrosion-resistant ceramic plating. SB1 boxes allow you to drive confidently with the best steering feel and performance on the market.
