A Dependable Rebuild Without The New Engine Price Tag

Shopping for an engine replacement usually means choosing between an expensive new unit or a used engine with an unknown history, and neither option feels great when it's your daily driver on the line. The DFC Diesel KORE Series Long Block gives 2007.5-2010 LMM Duramax owners a third option built specifically for value without cutting corners on the parts that matter. Every KORE Series long block goes in with new Mahle pistons and Mahle main and rod bearings, paired with Total Seal gapless piston rings for improved sealing compared to standard ring designs. New valves, seats, and guides round out the top end work, while fresh front and rear main seals help keep the rebuild leak free from day one. DFC machines every component to OEM specifications or better, so you're not sacrificing precision just because you're choosing the more affordable series. Since a long block arrives as a short block with cylinder heads ready for final buildup, you'll be transferring your bolt-on components like the valve covers, intake, exhaust, fuel system, and turbo over from your existing engine. Whether you're running a daily driver that needs to stay dependable or a commercial truck that can't afford downtime, this long block gives you real Mahle components without paying new-engine pricing.

Precision Machining Paired With Genuine Mahle Components

The DFC Diesel KORE6607510LMMSOALB is a remanufactured long block engineered specifically for 2007.5-2010 GM Silverado and Sierra 2500HD and 3500HD trucks equipped with the 6.6L Duramax LMM engine, compatible with both standard and automatic transmission applications. The long block assembly includes new Mahle pistons, new Mahle main bearings, and new Mahle rod bearings, paired with Total Seal gapless rings for improved sealing compared to standard ring designs. New valves, seats, and guides are installed during the rebuild, along with new front and rear main seals to help ensure a proper seal at both ends of the engine. A complete gasket set is included for installation, and every component is professionally machined to meet or exceed OEM specifications. To maintain warranty coverage, a new oil cooler, new air, oil, and fuel filters, a new water pump, and new lubricating oil are required at the time of installation, and the manufacturer warranty is void if the engine isn't installed with the fluids specified. The KORE Series is manufactured in an ISO 9001:2015 certified facility, and unlike DFC's standard engine line, it carries a 1 year unlimited mileage parts-only warranty that applies to both personal and commercial use.
