Description

The DFC Diesel Street Series Long Block is a remanufactured engine designed for 2007.5 to 2010 Duramax-powered 2500HD or 3500HD trucks. It focuses on reliability upgrades over stock, with improvements like ARP or OptiTorque head studs for enhanced clamping strength and Total Seal gapless piston rings for better compression. The oil pump gear is upgraded with DFC’s custom EDM doweling for long-term reliability. It comes with a 5-year, 160,000-kilometer warranty. This particular part number, SS6607510LMMSOALBCC, includes a Callies Crankshaft.
