Diesel Truck Engine Overhaul

Overhauling your diesel engine returns it to a "like-new" condition. After a full disassembly, the engine's parts are inspected, cleaned, repaired, or replaced depending on their level of wear. Then, we test for performance and ensure the engine is running like it did when it came off the factory floor.

A commercial overhaul is one of the most cost-efficient ways to get your engine back to running at full capacity. Compared to purchasing new and even used engines, there are considerable cost savings and often an engine overhaul. Often, an overhaul will offer better performance than what you'll get with a brand-new engine.

Regardless of what your engine rebuilding needs are, we are here to help. Contact us today for a free, no-obligation quote.

I drive hot shot and had a situation where all my clearance lights went out. I called early in the morning and they got me in same day and had the problem fixed next day. It was a completely unreasonable ask as it was an electrical issue that I needed done in a 2 day window, not to mention they were slammed. These guys went above and beyond for me without a fuss and communicated every step of the way.  I HIGHLY recommend them to anyone. Thank you guys for all your help!

Absolutely the best customer service. I went in seeking a hard to find item that I did not want to have to wait for from amazon. To my surprise they had what I needed and made my day that much easier for my trailer repair.

We are so thankful that our motorhome was towed to JE-CO. After a very disappointing breakdown, JE-CO has been so accommodating and helpful. They have easy access, long business hours and have worked well with Ford and Tiffin to try to get our rig repaired . We would highly recommend them.Also, thank you G for keeping us informed on what’s going on.
