The engine is the heart of your heavy duty commercial vehicle and over the course of so many miles it will experience stress and deterioration. This is just a fact of life on the road, but we can help keep your engine running for years to come with regular preventative maintenance and repair. Many issues start small and then balloon into major problems if left untreated. Don’t ignore any unusual noises, grinding, or sluggishness from your engine. Let United Diesel check your engine and make those repairs now, while they are small and manageable. This will greatly increase the life expectancy of your diesel engine and keep you on the road longer.

Heavy Duty Engine Overhaul


Sometimes it becomes necessary to take larger steps to keep your diesel engine running its best and your truck safely on the road. Whether your engine has reached its end or you’ve decided to give your truck more power and life, an engine overhaul can bring your vehicle back to new or even better than new.

When overhauling an engine, we rebuild your engine components back to manufacturer’s standards and in some cases even beyond. After an overhaul you can expect more power, better fuel efficiency, and longer life expectancy. After an overhaul, your diesel engine will roar back to life and purr with increased compression and reduced friction, giving you the performance you deserve.
