FONTANA'S
DURAMAX SHOP.
NOTHING
ELSE.
Eli Grijalva started EGR Diesel because diesel truck owners in Fontana deserved better than dealer prices and generic mechanics. He tells you what's wrong, fixes it, and charges a fair rate. That's it.
The shop is in Fontana and handles diesel trucks only. Mostly Duramax. Eli works on personal trucks, work rigs, and contractor fleets. Routine maintenance to full rebuilds.
