I was extremely happy with the disk break conversion package purchased from Lugnut 4x4. High quality components and every part fit perfectly. Shawn's expertise helped me thru difficulty I was having with a brake component unrelated to the conversion kit. I would highly recommend lugnut4x4

Awesome company with an awesome kit they put together at an unbeatable price. Was tired of dealing with rear drum brakes, leaking slave cylinders and doa parts. All the parts showed up in two flat rate boxes which is an awesome way to save a ton of money on shipping. Everything went together perfectly. Very happy!!

Kit fit as advertised with no issues. After a year I needed to change a rotor due to some accidental damage. I had miss placed the parts list that came with the kit. Needing to know the part number for the rotor, I emailed the contract us link for a copy. Being a Saturday morning I wasn't expecting a response till the following Monday or Tuesday. I received a message with the parts list within in minutes. Customer service is top notch.

Had an order with Lugnut 4x4 it was shipped immediately but delivery USPS Richmond Virginia had miss placed the 2nd part off the order for 3 weeks. Within that 3 weeks of waiting I informed Shawn at Lugnut 4x4 and he insisted on helping me with a backup and no additional charge! Was awesome because I Opted out of shipping insurance. The new back-up was shipped immediately again and it was finally received in few days. With all parts together the install went easy and smoothly! I highly recommend Lugnut 4x4 for parts and great customer service!
