PEM Racing Ford 9 in. Grand National Rear-End Assemblies

PEM Racing's Ford 9 in. Grand National rear-end assemblies are used for their strength and durability, particularly in racing applications like circle track racing and high-performance street cars. Chosen for their ability to handle high horsepower and extreme cornering forces, the 9-inch design features a full-floating axle, meaning axles are not attached to the housing and instead carry the load independently, offering enhanced safety and reliability compared to traditional axles. The removable center section of the 9-inch rear-end allows for easy gear ratio changes, making it a convenient choice for racers who need to experiment with different gear combinations. Show Less
