Installation Tips

Installation note:

The inside diameter of this rotor will accept an axle flange that has a diameter of 6-1/4" or smaller. If your axle flange exceeds 6-1/4" in diameter, you will need machine your axle flange to decrease your axle flange diameter to fit this rotor as necessary.

When utilizing an aftermarket axle with disc brake conversion kits, it may be necessary to reduce the diameter of the axle flange to a diameter necessary to adequately fit inside the required Clearance I.D. that the brake hat/brake rotor will require. (see above diagram for illustration)

This rotor has been designed for use with aftermarket axles such as Currie that have a 2.795" pilot. If you are using stock axles, or your axles have a pilot that is smaller than 2.795", we offer Part # 91031039 with a 2.790" Center Hole Diameter that is better suited to these applications.

I use this product on ford 9" rear with G-comp Rear suspension by Speedway Motors. It's not the biggest Rear disc but what I had to start off with. It works with floating caliper. Customer service helped me choose this setup to save a few dollars. After buying new torque arm suspension and Rear my budget was getting low.
