DO NOT DO BUSINESS WITH THESE PEOPLE! VERY DISHONEST!they did the old bait and switch I purchased the rebuild kit for my Cummins and they advertise parts like Mahle, Clevite, and Cummins. sent PAI garbage! 30% failure rate on the head gaskets!I didn't buy ARP head studs to install this junk!I've been duped!

Will be buying everything I can from these guys. Absolutely outstanding service, quick, polite, knowledgeable staff. Ordered injectors and ended up wanting to change them back to stock they gave me no troubles returning them and in a quick and timely manner. Mitchell was a huge help through the whole process. Would highly recommend.

After posting to a Cummins forum, Jacob responded quickly to my post. He started asking questions to find the right clutch for my application. When I called him and asked a bunch of questions myself he was very knowledgeable and didn’t over sell me to one item. He made sure to sell me the right one for my truck. He was also very patient with my questions, thank you for that!! This company has earned my business and I will be recommending them to friends and family.PS not sure how the clutch actually performs for me yet but I have high expectations and I’m pretty positive it will do it’s job.Valair organic dual disk quiet2016 2500 Cummins G56

Friendly service. Very knowledgeable about their products and the vehicles operational needs. Great prices and products. Quick shipping. I feel when I have a question about something I want a professional 2nd opinion that I can get my answers here. I had asked a couple questions about getting the right injectors for matching my turbo size along with the other mods and I got answers by the next morning that assured me I was on the right path. Friendly and constructive advice. I will be happy to shop here over and over and always feel like I'm not a nuisance asking questions and the price is always right.

Great customer service! Mitch was super helpful with any questions I had, and also hooking me up with a military discount. Most other companies were a few weeks out on their 2G swaps, but I had mine shipped within 3 days along with a Steed Speed manifold. I highly recommend them!
