New Cummins 6CT 8.3L 12 valve engine overhaul kit. This is a comprehensive rebuild / overhaul kit for your 8.3L Cummins Engine. We use only quality gaskets and OEM style pistons / sleeves designed to keep you running longer.

We use multiple suppliers most of which are tier one suppliers that make the components that you purchase direct from the dealer. All items are held to a "FLEET" Grade standard. Fleet Grade means the parts are built to hold up in a commercial environment and far surpass what you find in a local auto parts store.

The image above is an "example" of the overhaul kit and may differ to your engine type. We send the kit that matches your engines needs. We may contact you to confirm Engine Serial number / Vin so get that ready to ensure compatibility. Please note we are not responsible for miss-ordering the wrong bore, bearing size, or engine model specific parts. There will be a restocking fee for exchanges of unused parts. All used parts can not be returned. Most class 8 / 9 truck rebuild kits come in two options In-Frame and Out-of-Frame / Complete overhaul kits. Below we explain what comes in each kit.
