"The best truck diesel shop in Bakersfield... a full service bay with honest people."

"The best truck diesel shop in Bakersfield. They did a full engine overhaul on my Peterbilt and had it back on the road fast. A full service bay with honest people — I won't go anywhere else."

Ricardo M.

"Miguel took care of my 90-day BIT inspection and found a few things I didn't even know about. Fixed everything same week. Maria handled all the paperwork perfectly. Highly recommend for any fleet owner in Kern County."

Jorge T.

Fleet Manager · Delano, CA

"Called about a DPF issue on my Freightliner and Miguel diagnosed it the same day. They cleaned the filter, replaced the sensors, and got me back on I-5 before the weekend. Straight shooters, great price."
