Heavy-Duty Truck Engine Repair Is Our Specialty

Heavy-duty engine work is where we do our best work. We handle full engine rebuilds on Cummins and CAT platforms, from a top-end refresh to a complete teardown and reassembly. Our Harahan shop runs Cummins and CAT diagnostic software, so we are reading your engine the way the manufacturer intended rather than guessing from generic data. We also perform Cummins fuel pump rebuilds in-house, which keeps a common and expensive failure from becoming a multi-week wait on an outside shop.

Beyond engine work, our equipment lineup covers the jobs that keep a truck earning:

Air conditioning repairs
Flywheel resurfacing
General mechanical repairs
Preventative maintenance
…and more!

We stock Cummins parts, and we keep older parts on hand that most suppliers no longer carry. Older trucks are still out there earning a living, and their owners should not have to scrap a perfectly good rig because a component has been discontinued. If we have it on the shelf, your truck moves days sooner. Every heavy-duty truck repair and service we perform carries a six-month warranty. We stand behind our work, and customers come first.
