"Jay and his staff rebuilt a motor for me on a 2013 GMC 4x4 truck. They did a super job, and I am so appreciative! Jay is a great guy, a true pleasure to work with, and I look forward to working with him again."

"I had them to work on my 04 f250. Had a huge oil leak (2 quarts a day) also my high pressure oil pump and several injectors went bad. He called me every step of the way to keep me up to date on cost and what parts where bad. He knew this was a company truck and we needed it back asap. He stayed on it until late hours to get the truck back in a timely matter. Truck and motor was covered in oil from the leak from the last several months when I pulled in I didn't even recognize my own truck it was so clean he even acid washed my wheels for me. Went above and beyond to do fantastic work for us. He will be working on everything I own from now on!! Awesome job guys cant think you enough!"

"Quite simply the best place I've ever had work done. Usually do it all myself but due to time constraints and no space at the time, i messaged these guys. Got me in early on a sunday morning, did the work needed and even took time to stand around and BS for a little bit. Jay and his crew are great, good people at this shop and will be utilizing their services again. Definitely recommend to anyone!!!"

"My transmission went out on my 03 Avalanche, so I called Jay and he was busy, but made sure to fit my truck in! He rebuilt my transmission and had it back to me in less than a week! Fastest turn around I had ever seen! I am very pleased with his work and highly recommend KandJ! Thanks Jay!!"
