“What can I say other than this is a fantastic company. Matt went far and beyond working on my truck to get it back on the road . First, he changed the upper or pan for one with a gasket because it had blown a leak and rear main seal while he was in there . Everybody knows how big a job that is . While he had it in the shop, he went ahead and did a CP4 swap to the DCR .No more worrying about that dreadful CP4 disco party . He also fixed a lot of stuff that he showed me that was potential issues for leaking coolant . Stuff that nobody would think of. I would recommend this company , Matt , and his guys 110% for sure . If they had 10 stars, I would go with 10. Thank you Matt and crew for getting me going again.”
