Mopar Disc Brakes

General Info:

Rustyhope disc brake kits are priced at $215 for Dodge Truck and Mopar cars with four hole spindles, and for Dodge, Chrysler, Plymouth, and DeSoto cars with standard diameter three hole spindles.  Kits for pre- 35 spindles are $245.  Kits for all cars and trucks with undersized spindles are $315. Shop labor to drill and tap your spindles is $115, spindle turning is $150. All prices quoted include shipping to US addresses.  International shipping is higher, inquire to olddaddy@rustyhope.com for shipping quotes outside the US.

The standard kits fit a variety of years, makes, and models of Mopar vehicles. Virtually all Dodge/Plymouth/Fargo trucks and Dodge, Chrysler, Plymouth, and DeSoto cars, from 1929 through roughly 1960 can be converted to disc brakes using one of my kits. NOTE: The standard kits will only fit spindles with a 1.250 or 1.375 OD where the inner bearing fits and a .750 OD where the outer bearing fits. Undersized kits for spindles at 1.189 diameter are available at an increased price. Spindles with larger diameters can be turned down and converted.

Note: Installing this kit will change the track width on your vehicle.
Depending on the year, make, and model as well as your wheels and tires the track will increase as little as a fraction of an inch or as much as 2″ in some cases. I am not aware of any installation that the track width prevented the kit from working as designed and performing as intended.

All kits include caliper brackets, spacers, hardware, parts list and instructions. You will also need to purchase rotors, calipers, pads, bearings, seals, lug nuts, brake hoses, banjo bolts, and cotter pins. The necessary parts are commonly available nationwide at a variety of parts stores including Napa, Autozone, Advance/Discount, Riley, Pep Boys as well as many others. The rotors on my kits are a Mopar item with a 5 on 4 1/2″ bolt pattern. The calipers are GM, and the seals, bearings etc. are all off the shelf standard parts. The necessary parts can be purchased for as little as $200 to as much as $300 depending on your location and the parts source you choose.

The conversion requires you to be able to drill and tap two or three mounting holes on each spindle to 5/8″-18 fine thread depending on which vehicle you are converting. Trucks and early Cars have two holes, and later cars have three. (some early spindles do not require drilling and tapping, simply bolting together) You will also need to drill out the holes in your steering arms to 11/16″ which is clearance size for a 5/8″ bolt. I can do this work for you as stated above for $115 in the US, and slightly higher to Canada and elsewhere.

Standard inner bearing diameter is 1.31” and requires turning to standard 1.25” bearing size to be converted to disc brakes.

Note: Year range of the kits below is approximate. Many vehicles have
more than one spindle option for a model year. Find the spindle that matches yours below and contact me if your vehicle is not included in that kit’s year range.
