There's no good time for your truck to break down. We get it — you'd rather be behind the wheel and not end up on the wrong side of a tow. But ignoring problems is only ever going to make things worse, so when your engine is running a little rough and you're looking at options, what do you do?
In most cases, we try to direct our customers toward engine rebuilds rather than replacements. They’re more cost-effective and convenient in most cases.
When we rebuild, everything is done locally and in-house so that your engine rebuild is done specifically for your truck. Overall, we are a complete diesel engine service centre solution. In the event that a rebuild isn’t recommended, we’re also equipped to convert to a brand-new engine.
Typical engine rebuild costs range from $2,500 to $4,000+.
If we think that an engine replacement will be more beneficial to you than rebuilding your old engine, we’ll get it done. Sometimes, finding specific parts for your diesel truck engine can be hard to come by, even with our extensive OEM parts inventory. This is when we recommend an engine conversion. Not only will you unlock additional horsepower, but it'll increase fuel efficiency and the life of your engine.

Very happy with the work done at Cotton’s Custom Diesel. Appreciate their effort to get me up and running at a fraction of the cost the dealer was charging.

Amazing people and outstanding service! I came in to get a leveling kit installed on my Silverado, and they gave me a very competitive quote and did an excellent job. They’re genuine, down-to-earth folks who clearly love what they do—and it shows. Their shop is clean, organized, and fully equipped to handle just about anything. This will definitely be my go-to shop for any future upgrades I want for my rig.

These guys worked past closing on a Friday to get my truck done! Glad I drove almost 2 hours from home to get the work done. Well worth the drive.
