Replace your old gear carrier with one of these Moser Engineering steel full spools to save weight, improve performance, and increase the life of your rear-end components. Moser's steel spools are heat-treated and precision-machined. For racers watching their weight, aluminum spools are available for Ford 9 in. and 12-bolt GM units. They feature a thicker ring-gear flange and a large-diameter midsection for increased strength, and they weigh approximately 4 lbs. less than steel spools.
