“The free next day air shipping for my Edge Evolution CTS2 was awesome. It showed up the next day as promised, and my Duramax is WAY more fun to drive now!”- N. Benson – El Paso Texas. 2016 Chevy Silverado 2500 HD. Edge Evolution CTS2 85400 for Duramax LML

“I really appreciate that your inventory was accurate and up to date. I had been having a really hard time finding the Mishimoto transmission cooler for my 7.3L Powerstroke -
they were out of stock everywhere I had checked. Came across your site, said you had 6 in stock and sure enough, you actually did. Shipped out the same day I bought it too!”- Rick Thompson – Topeka, Kansas. 2002 Ford F-250 7.3L Powerstroke. Mishimoto MMTC-F2D-99SL

“When I called in and asked for a recommendation for a cold air intake for my Ram, your sales guy Daniel recommended S&B. He took the time to explain why too. Now that I’ve had the intake installed for about 3 months I see exactly what he was talking about. Great job! - Dennis L. – Ohio. 2017 Ram 3500 6.7L Cummins. S&B Intake 75-5068

“It’s not often you get the high level of customer service like I got from U.S. Diesel Mods. I ordered two different parts, and turns out they weren’t compatible. Rather than just ship them to me, your customer support guy called to verify my order with me and explained the issues I was going to run into based on my initial order. We got the order changed around and now my diesel runs exactly like I wanted it to.” - D. Gentile – Clovis California. 2008 Dodge Ram 2500 6.7L Cummins.
