I hardly ever give feedback or reviews on things I buy and when I do it’s generally if something isn’t worth purchasing, that said I’ll start with the customer service, I spent a lot of time researching and looking at conversion kits, emailed a few places asking a question about my main concern (cab chassis and srw) and got no replies BUT did receive a reply back from Shawn within a few hours, after a few emails my phone rang and it was Shawn(had to give my # in order to contact them)! He wanted to verbally speak with me to make sure we were on the same page so I could get the proper kit, that sealed the deal for me! The shipping was fast, even for USPS lol, the kit came in 2 boxes and I could tell by the condition of the boxes that good ol USPS didn’t respect the 2 bright red and yellow stickers that scream FRAGILE HANDLE WITH CARE, but whoever packed the boxes gets an A+! They used foam, paper and even a couple pieces of 1/8” plastic so the calipers wouldn’t touch the rotors. The quality of the parts is good, I’d say you get more for what you’re paying for, and compared to anything else out there for kits your paying way way less, almost half of what others are! Not sure why there’s a handful of one star reviews but if you read/think about each one you can decipher why or what the problem was, like the one with the bracket “bending” I’d be willing to bet the guy doesn’t have a proportioning valve in the system (brackets are warranted anyways drrr), or the review saying the calipers were poor quality so he used them for cores to buy some at Napa for $20 each….ummm sure those are definitely not poor quality for $20 lol, if I could add a pic of the calipers I would, they are good quality, another plus about the parts is they, Lugnut4x4, give you the actual year, make and model of the vehicle you’d use to get replacement parts!!! They didn’t have to do that, no other place does because they want you to think it’s a “special” part and you must get it from them only (I’m sure that’s how that one dude got those $20 Brembo calipers from napa). So my overall opinion is you literally can’t beat the price and if you don’t care for the quality then at least you would now have the information you need to go buy whatever you like! As for shipping the packaging is top notch, if it’s damaged then point the finger at the over worked delivery driver that played toss the package around with it! Oh and you get a sticker! Sure big deal a sticker right!? Well Rough Country or Super Lift has gotten a lot of my money, could probably buy a knew 2023 truck with the amount, and not one damn sticker!

Absolutely love this product, great craftsmanship and very easy to install. Had some questions after my purchase and got very fast and very good customer service. Would recommend this disc break conversion to anyone that is looking.

Shawn responded right away on a SUNDAY afternoon! I was in the middle of my drum brake job, and couldn’t figure out which rear end kit I may have needed. He was prompt honest but unfortunately did not have a rear disc brake kit for my application. If I ever replace the rear end for one that has a kit, he’ll get my order!

Poor fitment and customer service. Kit that I ordered for my application does not fit. After close to a week of countless pictures, measurements, and emails still no resolution. Other are having issues with the fitment as well. Shawn admitted he can see in the pictures that it's not fitting up and I asked for another set of brackets to try and a return label and I would send my originals back when I swapped them but he doesn't want to do that. Kit I ordered was for a 78 and up Ford kingpin Dana 60. My axle is a 79 Ford Dana 60 with factory outers other than the Chevy rotors supplied in the conversion kit I purchased.

I'm sorry about the confusion. I asked you to return the brackets so we could replace them. You wanted me to send new ones first. All warranty items require you to send the defective parts back first.

Opened the box and right away I could tell they had sent me 2 different brake calipers. Took pictures with measurements and they tried to deny that they were different. I turned in the wrong one they had sent me into the local auto parts store as a core for the correct one and lugnut4x4 only paid for half of what it cost me. After just one week of driving around with everything finally installed, the brakes started to feel like they're rubbing. Pulled the wheel off and the force of braking is actually bending the soft steel brackets, and causing the brakes to rub both unevenly, and constantly. Don't waste your time and money on this company. Every interaction I've had with them has been very unprofessional. They are not interested in fixing their mistakes.

I'm sorry you are unhappy. We tried many ways to resolve your caliper problem. Our brackets have an unconditional lifetime warranty. Feel free to contact us for warranty replacement if you wish.

Product was satisfactory but my customer service experience was fair at best. Answers were vague and seemed to be misleading regarding product info. I would not recommend this company based on my experience.
