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.

Communication with this customer was very difficult. He dropped some parts and felt it was my fault. There was a lot of vile language and threats from his end. I tried my best to remain polite. We use lots of fiber reinforced tape to make sure boxes stay together, but it is still possible to a box to get damaged in shipping. It's important to be carefull when carring a heavy box. I'm sorry but we are unable to replace someone's floor if they drop parts.

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

Warning: Stay away from this company "Lugnut4x4.com" I ordered a diskbrake conversation kit for a Dana 60 rear axle from these guys for 498.78. Now the problem is how it was shipped, Shawn shipping very heavy parts in a flat rate box by the USPS. Here lays the problem with that the first box was delivered with the rotors, and hardware. but the parts were so heavy that it destroyed the box. And when I called Shawn at lugnut 4x4 he stated it happens, I told him it was packed in a heavy duty box this would not happen. He stated that the second package with arrive within a couple of days, well it did and the box was a flat rate box or what was left of it. Pictures below! I called Shawn again and again I got the same excuse it happens, I said twice in a row that is just poor choice of boxes and poor packaging period. The second box was not hardy a box anymore due to damage. I told Shawn that I was going repackage the parts up and ship them back due to 3 reasons which are stated 1. Poor packaging 2. Poor customer service (negative 10) 3. Parts are all made in China and are junk and parts were missing. Shawn is a internet company of him and three other people and there is phone number on the website to call. His excuse was that this is internet company. After trying to talking to him on the phone stating how unhappy I was with the broken and missing parts and the poor packaging I was told that happens and then hung the phone up. I am 67 and I would never treat my customers like that period.

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!
