I was looking into the conversion kit for replacing an '02 C&C with a drum from a '00 on a dodge ram 3500. Anyone looking for these knows how hard the disk is to find. Rather than make the sale, the team responded to an email I had asking if it would work on the axle within an hour on a Sunday, telling me that it'd work on the axle, but the brakes were undersized compared to factory. HUGE ACCIDENT AVOIDED! Glad the team is honest, on top of it, and happy to have a satisfied client rather than simply make a sale.

I have yet to purchase anything but I reached out in desperation. I recently purchased a pretty heavily modified jeep and have been struggling to figure everything out. I even took my jeep to an offroad specialty shop in michigan and they failed miserably while taking my money. I sent Shawn an email which he responded to quickly even without any transactions telling me what I needed. Above and beyond. He has won me over as a lifetime customer, to help someone you may not even make any money off of them leaves me nothing short of impressed and willing to do business with him any time I can. Thank you so much, I was about to give up and sell this when my wife has fallen in love with it.

I bought a rear conversion kit for my 1995 f 250 7.3 diesel 4x4 around 8 months ago it was fairly simple to install. I’m a contractor not a mechanic but it went pretty well. I had questions so I would call or email and mr miller was very quick to answer or respond back. Just this morning I emailed him and while on vacation he responded back to me asking what kind of brake pads I needed for replacement because I miss placed my copy of install and replacement parts list. To let me know what to get at my local auto parts. So you can’t beat that for costumer service lugnut 4x4 is awesome. I can’t believe the difference in stopping power.five stars for sure.

5 stars all the way. I purchased a rear conversion kit for my truck from Lugnut4x4. This was just after Hurricane Helene hit. Fast delivery. Great service. Quality parts. I definitely will buy from them again. Thank you Shawn

After doing a month of research as to what would fit my 72 Chevy C20, I decided to reach out to Lugnut 4x4. Shawn confirmed the kit I needed and sent me a link directly to the page where at least 8 ready made kits were available to choose from. Installation was easy if you have the necessary tools like a press but no welding required which was great. When I realized I misplaced a retainer clip, Shawn sent me out the missing part. These are quality kits and look great! So glad I decided to reach out to them.
