Just wanted to give a big thumbs up for Erik and the gang at Left Coast Diesel in Concord, CA. They were great to work with, very knowledgeable and honest. Erik even talked me out of spending extra on the 4.10's and he was exactly right!
I'll definitely recommend them to anybody in the area!
They did my Goerend HD trans build, 4" MBRP turbo back exhaust and PacBrake + controller. I'll be back!
