Drinnon and Mitch worked on my truck after another diesel shop had it and I wasted over 4k at the other shop. Steadfast diesel installed new heads...new everything to fix what the other shop messed up. It was a costly mistake when I took my truck elsewhere. Let me say Steadfast is an honest and fair priced shop that does great work! They have done everything from engine to transmission installs for me. Thank you Steadfast!!!!!
