Cummins Repair

The 5.9 and 6.7 Cummins is one of the toughest engines on the road, but it still needs the right hands. We keep them running strong and build them stronger.

The Problem

Cummins Repair, done right.

A Cummins that is down means a day you cannot work, a boat you cannot tow, or a load you cannot move. Guessing on diagnostics or throwing parts at it gets expensive fast.

From routine service to a no-start diagnosis, we handle the full range of 5.9 and 6.7 Cummins work: fuel systems, lift pumps, injectors, turbos, head gaskets, and the electrical gremlins that make these trucks act up. We diagnose it right the first time instead of guessing.

Want more out of it? We do FASS fuel systems, suspension and steering, and sensible performance upgrades that add power and reliability without grenading the truck.
