Proof it happens here
The overhaul photos on our Work page aren't stock pictures. That's a Cummins ISL9 and a CAT C15 torn down and rebuilt right in this shop.
How it works
Book a diagnostic, and we'll find the problem and give you a written estimate before any work starts. A deposit of 50% of your approved estimate is due before work begins; the balance is due when the repair is complete. Every repair is backed by our 12-month / 15,000-mile labor warranty.
Pickup & drop-off
Pickup and drop-off isn't available for big trucks or diesel trucks; those come to the shop at 611 Lafourche St, Lockport.
Diesel questions
Do you do complete in-frame overhauls, or just repairs?
Both. In-frames are a specialty here: we've rebuilt Cummins and CAT diesels in this shop, start to finish.
My diesel won't start / lost power. Can you find the problem?
Yes. Diagnostics come first. It's a flat $100, and your repair estimate is free once we know what's wrong.
How long does an in-frame overhaul take?
An in-frame overhaul normally takes around 40 to 50 hours of work.
