Great job creating this Dakota R/T Ground Affects Kit. Phil

Brian A.

The 408 engine runs strong, put on dyno 405hp with 415tq N/A not shabby.. also was on 22" wheels with those numbers est. 500-525 @ crank. Thanks so much, Brian

Matt G.

I just want to say thanks for all that you have done for me, because over the weekend I was the fastest R/T out there with no power-adders and still have stock suspension. I was running a 13.7 @ 102 in my CC and my closest competitor was running a 13.96, which he had heads/cam/intake/exhaust and a 9+ lb Vortech SC. Thanks and keep up the good work. Matt

Daryl S.

"Your 408 runs like a dream. I think we are well over the 400hp side, a new 300hp mustang could not overcome, it is a beast. I am very happy with the results, streetable, workable, & track ready.
Thanks for all your hard work, Daryl"

Alan P.

"First off, I just have to say that I have never came across a more stand-up guy that takes his time to connect with his customers and have the unmatched technical advice second to none.
Thanks again, Alan"

Don S.

"John, I can't emphasize this enough, but without the help you're getting me I could not have afforded my dream engine! I literally have cringed when thinking about how much it would cost to put together a mild performance engine. I couldn't have dreamed a year ago to be able to have this engine. Honestly John, the real story here is how you have helped a brother out on faith alone. Keep up the good work brother Don..
Semper Fidelis!!"

Robert M.

"John's very honest, something that's hard to find these days. This means he'll tell you the truth and you may not want to hear it. LOL. The best thing he did for me was make me feel like I was his 1 and only customer. He was always available when I needed help also. Will do business again.


bought numerous things and all transactions went very smooth. Responded to emails within a day or less. Ryan


Super guy to deal with! GREAT SERVICE!! GREAT PRICE!!

Brian C.

I have never had any problems with John on any transaction. One of the few vendors I have never had a single problem with. Including paying overnight shipping out of pocket due to manufacturer drop shipping the wrong part originally. Brian

Colton H.

"Johns the man, bought a 410 package from him years ago after I got back from overseas. The caveat I gave John was that it had to pass Californian emissions. Not only did it pass, but the motor he built me actually performed cleaner and more efficient than the stock one!!! John stands behinds his products 100% and is never afraid to tackle a problem. Much respect John, you've made my truck that my parents gave me into a donut eating machine.

I am very pleased with the quality of the magnum deep pan, and the best part is that it really is not much deeper than the stock pan so I dont have to worry about any road debris or anything hitting it. Thanks for your time!
