Hey everyone, we have moved but doesn’t mean we aren’t still in business! Now located in Utah!

Any 01 - 07 duramax guys looking for a one of a kind s400 kit? I’ve got some time on my hands and I’m looking to do another custom twisted s400 kit like the one pictured below. The goal is to film it and use it for my YouTube channel.

I NEED THE TRUCK IN PERSON SO MUST BE LOCATED IN UTAH!
