Precision Built For Demanding Towing Applications

The Tow/Haul Series Standard Speed Long Block from DFC Diesel is engineered for drivers who expect more from their 6.0L Powerstroke. Every engine starts with a thoroughly machined block, professionally bored to accept oversized pistons for a tighter fit and better performance. The cylinder heads are resurfaced, magnafluxed, and upgraded with all-new seats, guides, valves, and stem seals to restore factory-level sealing and airflow. This long block includes ARP series 2000 or OptiTorque head studs, ARP rod bolts, and Total Seal gapless rings for maximum internal strength and minimal blow-by. Chamfered piston bowls and ceramic-coated crowns help manage combustion heat more effectively, while dry film-coated skirts reduce internal friction for smoother operation. DFC installs a stage 2 billet camshaft and Manton HD pushrods to further improve valvetrain durability under high load. You also get a full top-end gasket kit and pre-installed rockers and pushrods, helping streamline the installation process. It's a balanced, ready-to-run solution that delivers both factory precision and long-haul confidence.
