PEM Racing's Ford 9 in. rear-end housings, specifically designed for Grand National applications, provides a combination of strength, customization options, and maintenance ease, making them a popular choice for high-performance vehicles and race applications. The 9-inch design, particularly when used with a full floater setup like the Grand National, is built to handle significant power and torque. The large diameter of the ring gear contributes to the housings strength, making it more robust than other types of rear-end designs. PEM's custom housings, like their Grand National full floater, are often designed with thicker tubes and stronger materials for added durability.

PEM Racing offers axle drive flanges in different wheel bolt patterns, designed primarily for Grand National hubs. They include a 3/4 in. bolt-on cap, O-ring, and hardware. These drivetrain components transfer power from the axle to the wheels. They're essentially a plate with splines on one side that mate with the splines on the axle—and studs or bolt holes on the other side that allow the wheel to be attached. Axle drive flanges are commonly used on Dana 60 axles and other similar axle types, particularly in off-road applications.
