To travel long distances while pulling a trailer that can weigh close to 80,000 lbs, your big rig needs an extremely powerful and reliable engine. Since the reliability of any system is determined by its weakest link, each and every replacement engine part you purchase should be of the highest quality. To cover your needs for best-in-class semi truck replacement engine parts, we have gathered them on our digital shelves. Regardless of the product you are looking for, whether it is a set of piston rings or a replacement engine head, we have the right option at an affordable price.
The engine of your semi truck must produce enough horsepower and torque to be able to move huge loads across the country day in and day out. Each year, you may cover up to 50,000 miles in your big rig or even more. It means that sooner or later some components and systems of your engine will require maintenance or repair. On the digital shelves of our online store, you can find a huge assortment of parts, rebuild kits, and complete semi truck engine assemblies that you may need to keep your machine on the road hauling cargo and making you money.
Since semi trucks need a lot of torque on low RPMs to be able to pull heavy loads with decent fuel mileage, almost all big rigs today run on diesel. You can increase the output of your powerplant significantly by adding a turbocharger or supercharger. Such a unit pumps more air into the engine thus allowing for adding more fuel to the mixture. The difference is that a turbocharger is actuated by a turbine propelled by the exhaust gases flow, hence the name, while a supercharger uses the engine power receiving it from the crankshaft through the pulley system.
Intercoolers are designed for further improvement of turbocharged and supercharged engine efficiency by cooling down intake air thus increasing its charge density. Increased airflow improves combustion, increases horsepower and torque. In our store, you can find a huge assortment of aftermarket intercoolers and all required hoses, clamps, and couplings. We offer a wide variety of top-notch engine blocks, including bare blocks, expansion plug kits, engine block heaters, and other related parts. Browse our extensive catalogs of crankshafts, camshafts, valvetrain parts, and more to find all of the needed components, such as seals, gaskets, and bearings.
All semi trucks work much harder than other types of vehicles which means they are subject to accelerated wear and tear and must be maintained properly to serve you for many years to come. The problems with your semi truck’s engine can have severe consequences. Too much smoke coming out of the exhaust pipes, reduced oil pressure, or loss of power are all signs of engine malfunctions. It is essential to carry out regular engine compression tests and provide timely maintenance to avoid more expensive repairs. Don’t forget to change the oil regularly to prolong the service life of your engine and reduce the chance of failure.
