Paid 12k to have motor done. Since I got truck back it's been nothing but trouble half the stuff I got charged for they didn't even do or replace. Half the parts under the hood are loose and falling off. All gaskets aren't replaced leaks ...

Mark had been working on my trucks for a few years now! His knowledge is worth every penny you will spend here! He has fixed one of my trucks that no one could find out what was wrong. I've seen some awesome builds out of this shop and they have all been done better than factory could do! I will be a customer for life!
