The F9HD fabricated housing center is 22 5/8" wide, features a 3/16" thick Hi-Form 50 steel body, a 3/8" thick Hi-Form 50 steel 3rd. member mounting face (that is notched for use with 10" ring gears), and is machined to fit 3.5" tubes. Unique to this design, the first bend in the housing is centered with the center line of the axle tube. This allows the bend to be the point of lowest ground clearance, and the flats on the housing to provide maximum ground clearance at up to 20 degrees of pinion angle! Another unique feature are the welded in bulkheads inside the housing that tie the face, the body, and the inner ends of the tubes all together. 3 1/2" tubes easily slide in from the outside and require minor grinding to flatten one side of the tube to key it into the inner bulkhead. Arguably the strongest fabricated housing design to ever hit the market! Sold each.
