After having some issues with another truck shop in So Cal I was looking for a shop that could install some off road bumpers, and airbag setup, wire some lights and a winch and do some fab work on my truck. Thomas and his team were fast, thorough and really fair with pricing. Great work, very happy. I'll be back.
