Q & A

What's in the Box

To help keep the cost of this full floating Ford 9 inch rear end down, This Grand National rear end assembly uses reclaimed original housings with new 3" tubes and ends. They have been cleaned and jig-welded to ensure straightness. Everything else is brand new and includes 31 spline axles, hubs, drive plates, 5/8" studs, bearings, seals, rotors and lug nuts.

Choose 58" or 60" width, centered pinion. Choose 5 on 5" or 5 on 4-3/4" bolt circles.

DRP Performance 10518 Grand National Rear Hub Bearing Spacer
(Part #91010518)

These hub bearing spacers allow for consistent and precise bearing load every time the spindle nut is tightened, regardless of the torque applied. Without a bearing spacer, bearings are typically over tightened to prevent loosening during the race. With a bearing spacer installed, you can completely tighten the spindle nut and the hub will spin free every time. Bearing spacers save time, reduce bearing temperature and greatly increase wheel free spin, putting more horsepower to the wheels. You can feel the difference by simply pushing the car!

Testing has shown that the bearing spacer will make more difference than any “Low Drag” bearing set up currently available. When the spacer is used in conjunction with “Low Drag” Tapered bearings and seals, you will have the ultimate Low Drag set-up. These adjustable bearings feature a threaded sleeve and set screw to ensure you'll never have to worry about an over-tightened hub again!
