Our disc brake kit features 11-inch vented rotors that are paired with the popular 1978-1988 compatible for GM "Metric"single piston disc brake caliper. These calipers use a 2.375 (2-3/8-inch) diameter piston and offer excellent stopping power in a floating caliper design. We include standard organic brake pads, but the caliper can be upgraded with any D154 performance pad of your liking should you desire a bit more pad "bite"in your system. Also included in our kit are new brake fluid hoses, bearings, seals, dust caps, and all mounting hardware. This brake kit will add 8-1/4 inches overall to your straight axle's center-to-center distance of your king pins. Meaning, if you are running a 48-inch axle, your overall width once installed will be 56-1/4 inches. This may be more or less than your current setup depending upon current brake package and wheel spacers. This kit requires a minimum of a 14-inch "disc brake" wheel, however we recommend a 15-inch wheel with a 2.80-inch hub I.D. that is lug-centric for proper clearance.

The caliper mounting brackets provided fit '37-'48 compatible for Ford spindles and are quite stout to prevent any caliper flex during hard braking. They are direct fit to the 1937-1941 compatible for Ford "round back"spindles. If you have the later 1942-1948 "square back"Compatible for Ford spindles this kit will still fit with some minor clearance work to the spindle to allow the caliper mounting bracket to properly compatible for seat to the spindle. And if you do not have any spindles at all for your project that is not a problem either, as we offer a beautiful set of forged Forged Early compatible for Ford Round Back Spindles that include new king pins with installed bushings to help you finish your project. Do not forget your Bolt-On Steering Arms too, especially if you are using a drop axle, as aftermarket steering arms will save a lot of time and frustration in this regard.
