Do NOT use them. I had them repair and rebuild a short block for a 6.0 diesel. They failed to recognize damage to the low pressure oil pump when they re-assembled the short block and ended up causing me additional $$$ for repair. They then proceed to blame the failure on my negligence. An addition to this, it took them OVER a month to do a simple bore and hone and replace pistons. Their owner only works for 3-4 hours per day, so obviously doesn't take the business seriously. Also, they are now located off of Broadway in Mesa, not on Southern.
If I could give zero stars, that would be great!
