Moser 9 Ford Nodular Iron cases are the toughest on the planet. Moser Nodular Iron Cases are available in two bearing sizes. The 3.062 side bearing size is made for posi-traction setups or spools with fewer than 35 splines, and the 3.250 side bearing size is made for use with 35 spline and 40 spline spools. There are a number of features that make our Moser case the right case for you. All Moser cases are heat-treated and stress relieved before all CNC machining is completed. In addition, Moser cases have forged steel caps with 5/8 bolts, machined adjusters, and are tapped for an oil filler plug. SAME DAY SHIPPING (if ordered before 2 p.m. est)
