Inframe/Overhaul Kits for Diesel Engines

Along with our sister company, Big Bear Engine, we remanufacture 40 to 45 CAT, Cummins, Detroit, John Deere, International, and Mack long-blocks every single month—and we’ll offer you nothing less than the same high-quality engine kits we use in the diesel engine rebuilds conducted in our AERA-certified facility. Each of our engine rebuild kits is tailored to your specific engine serial number. This ensures you get the right part number, the correct fitment, and maximum durability every time. All of the 15,000+ products we carry are produced in ISO 9001 factories, which is to say they’re built with the highest quality control standards in place. With our inframe and rebuild kits, you can rest assured that only the best parts in the industry have made it into your diesel engine rebuild kit.

Depending on the application, your inframe engine kit will include replacement cylinder liners (with liner seals) and OEM-spec pistons, complete with piston rings, pins, and pin retainers. Replacement crankshaft main bearings, connecting rod bearings, an upper gasket set (which typically includes the head gasket, exhaust manifold gaskets, and the intake manifold gasket), and a new oil pan gasket will also be part of the contents of our engine rebuild kits. A comprehensive set of required O-rings, seals, and other gaskets will be included as well, neatly packed in a box to simplify your order.

Our customers rely on us as trusted suppliers to provide high-quality kits that fit their vehicle and application needs. Whatever your category of engine or type of rebuild, our extensive line of engine rebuild kits ensures you’ll find the perfect match for your project. Add the right engine rebuild kit to your cart today, and experience industry-leading durability at competitive prices, backed by stars of customer satisfaction.
