Our Mission

As a truck and off-road enthusiast, owner and founder Shawn Miller makes it his mission to sell the best quality disc brake conversion kits at the best price (with free shipping!). We make it easy to get the exact kit you need, with extensive customization options offered on every kit. If you have a question or a problem, we’re ready and willing to help (and you always get a real person, not an automation).

Our History

Off Roading With Ford DanaIn 2003, Shawn started getting into 4-wheeling and was building a ’78 Bronco. He upgraded the axles to a Dana 70 rear and 8 lug Dana 44 front and did every other brake upgrade he found on the internet, including a different master cylinder and booster. He was never happy with the results. He’d adjust the rear brakes and it would be okay for awhile, but not for long. It felt as if he had to push the pedal through the floor to get it to stop when on the trails.

Finally, Shawn ordered a disc brake kit for the rear and all those brake problems went away. He paid over $400 for that conversion and thought that price was way too high. Shawn started putting together his own kits, and decided to share his knowledge and products. Now Lugnut4x4 specializes in disc brake conversion kits at a fair price and shipped for free.

Why Lugnut4x4?

In addition to stocking the highest quality products, we’re committed to you, our customer. Lugnut4x4 is a small, family business, and questions that aren’t answered in our FAQs are answered directly by Shawn Miller, the owner and founder. We are a small team that values responsibility, cooperation, honesty and communication. Our goal is to provide each and every customer with prompt, professional, and personal service, even if our only interaction is a simple ‘thank you’ for choosing us.  It’s our honor to serve our customers, and we want you to enjoy both your experience with us and your new brake kit.

What Makes Our Kits Special?

  • We use steel banjo bolts or coated bolts for all applications because regular bolts rust.
  • We use grade 8 zinc coated hardware for maximum rust resistance.
  • We use brand name brake pads instead of cheap imported pads.
  • Most of our kits have three different calipers to choose from, clockable brackets, different pad options, and slotted rotors are available for most kits too.
  • Our basic disc brake conversion kits start at $315, and the price includes priority shipping on US orders.
