SoCal Diesel isn’t just another diesel performance shop. It’s the result of over 40 years of hands-on racing, engineering, machining, and manufacturing experience, all focused on making Duramax engines faster, stronger, and more reliable. Founded by Guy Tripp, a pioneer in high-performance cylinder head design, SoCal Diesel was the first to bring CNC ported Duramax heads to the market and has been leading the charge ever since.
Guy’s background is the real deal. From developing race-winning cylinder heads for NASCAR and NHRA to building robotic manufacturing cells that run lights-out, his career has been all about pushing limits. That same innovation now fuels SoCal Diesel’s lineup of Duramax parts, designed to handle extreme competition and high-horsepower daily drivers alike.
From their advanced cylinder heads to proprietary valvetrain components and tuning support, SoCal Diesel parts are built with race-engine precision and tested in real-world abuse. Their close collaboration with EFILive helped make Duramax tuning accessible to the public, and their full catalog of performance parts is built to support everything from weekend warriors to all-out race trucks.
