Great customer service
Great customer service. I didn't even buy the disc brake kit, it came with a truck I bought but Shawn was super responsive and got me the installation guide, after hours, within mins of sending the email.

I have a conversion kit currently on my 95 gmc k series truck and would like to thank lug nut 4x4 for the best product and service. I installed the kit relatively quickly without issues over 5 years ago and I am terribly tough on my vehicle. I have no issue I am getting ready to replace brake pads and I just want to thank lugnut 4x4 for a great kit that has been tested in an extremely rough and brutal process I love it and would 100% recommend your products.

Took the time to answer my questions and help me find what I needed unrelated to one of their kits. That kind of service is rare to say the least. I highly recommend these guys.

Lugnut4x4 Customer service was outstanding. I had ordered longer wheel studs and complete front disc brakes for my Dana 60. Everything fit as it should. Great business. I will be ordering more parts. Thank you Shawn

On Saturday, August 30, 2025, I checked my brakes on my 1997 F250 4x4. I had previously used a Lugnut4x4 conversion kit to convert my Sterling rear end to disk brakes. Union inspection I found that my right caliper was leaking. The has been installed for around two years and trust me when I say I have abused my brakes on & off road. I sent an email to Lugnut4x4 not expecting a response due to the holiday weekend. I was wrong! Within 5-7 minutes Shawn responded and after a back and forth on several emails we came up with a solution. I decided against rebuilding my standard calipers & now have the heavy-duty calipers heading my way. I cannot believe the customer service Shawn took the time to deliver! On a holiday weekend! Lugnut4x4 will have my gratitudeand business forever!
