As long as your Mittler Brothers hubs use 2 1/2" ID bearings then this hub can replace your current ones. The drive flange and axle cap are different so you will also need the flange kit 91048380 as well as drive flange bolts 91048385-2 and o-ring 8027478. Most likely you would be better off getting the entire hub kit 91048400 since it comes with new bearings, seals, and lug nuts as well.

what is the backspacing? I'm going to use these hubs to replace a standard axle with a 3" backspace steel hat, so what is the backspacing from the wheel mounting surface to the disc mount on these hubs?

This hub measures 2.590" from the wheel mount surface to the rotor mounting surface. Keep in mind that you will also have a drive flange pushing the wheel out by the thickness of the drive flange. Our Speedway drive flanges are .200" thick.

It depends on the snouts you have on your housing. If you have hubs from Speedway Motors, Winters, Afco, Ace, or PEM these will fit.

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!
