Cummins Specialists
Cummins powers trucks from nearly every OEM, so we see the X15 (ISX), X12, L9 (ISL), and B6.7 (ISB) across the board. With Cummins INSITE diagnostics we go straight to the fault injector, turbo, EGR, or aftertreatment and handle everything from a single cup seal to a full in-frame overhaul.
Whatever chassis it’s in, if it’s Cummins-powered, we service it.
