The Redneck Ram can be ordered in several different lengths. Typically a Dana 30 and some 44s use a six-inch ram, where other Dana 44s and Dana 60s need an eight-inch unit. Our Rockwell axle needed a nine-incher. The length needed can vary so make sure you measure your tie-rod swing before ordering. The rams are available in 1 1/2-inch and 1 3/4-inch bores. The 1 3/4-inch units will provide more power assist but will move slightly slower than the 1 1/2-inch units. We weren't too worried about speed and we had plenty of room, so we went for the 1 3/4-incher. We centered it and tack welded it in place then checked for clearance when turned. Mount the ram as parallel as possible to the tie rod it is being attached to.
