1957-1971 Dodge D100 Disc Brake Conversion Kit

Pirate Jack D100DBK – 1957–1971 Dodge D100 Front Disc Brake Conversion Kit (2WD, 5-Lug)

Finally, a disc brake conversion made for your Dodge D100.

If you own a classic Dodge D100, you know the search. There are disc brake conversion kits everywhere for Chevys and Fords, but try finding one for a D100 and the options get thin fast, and the few you do find usually cost a small fortune. That’s why D100 owners are always glad when they find us.

The Pirate Jack D100DBK is one of the few drum-to-disc conversion kits built for 1957–1971 2WD, 5-lug Dodge D100 trucks, and one of the most affordable ways to get there. It gives your classic Dodge truck the stopping power, control and confidence of modern front disc brakes without a custom fabrication bill.

Why convert your D100 to front disc brakes?
Old drum brakes were fine when your D100 rolled off the line, but they can’t keep up with today’s traffic, heavier loads or the way you want to drive your truck.

• Stronger, more confident stopping: Discs shed heat better than drums and resist fade, especially when you’re hauling or towing.
• Better in wet weather: Discs clear water fast, so your brakes come back quickly after rain or a puddle.
• Less pull, less adjusting: Disc brakes stop straighter and self-adjust, so you’re done chasing drum adjustments.
• Modern wheel options: The conversion lets you run 15" or larger modern disc brake wheels.

Everything you need for the brakes, in one box
The D100DBK isn’t a bracket kit that leaves you hunting for the rest. Rotors, calipers, pads, brackets, bearings, seals, dust caps and hoses are all included, so your front brakes arrive ready to go.
