Get Your Powerstroke Back On The Road Right

When your 6.0L Powerstroke lets go, you don’t just need a replacement, you need an upgrade that’s built to last. The DFC Diesel SS60050618AUSOALB Street Series Long Block gives your 2005-2006 F250 or F350 the strength and reliability it was missing from the factory. Designed for work trucks, daily drivers, and diesel fans who want dependable power, this engine includes critical improvements to the failure points that plague stock motors. From ARP head studs to Total Seal gapless piston rings, every piece is chosen to keep things sealed tight and running strong under pressure. It’s backed by a 5-year, 160,000km warranty, which shows you just how confident DFC is in their craftsmanship. Whether you're hauling tools, driving cross-country, or just want a smoother ride to and from the jobsite, this long block delivers performance you can count on without going overboard. It’s a solid step up for anyone who wants more peace of mind and less time under the hood.

Precision Built To Outlast And Outperform Stock

DFC’s Street Series long block is far more than a basic reman, it’s a full performance-minded rebuild designed with the daily user in mind. Each engine starts with a professionally machined block, bored for oversized pistons, and assembled using all new OEM or equivalent components. That includes new pistons, rings, bearings, seals, and a complete top-end gasket kit to ensure consistent performance and oil-tight operation. The cylinder heads are fully remanufactured with all new seats, valves, guides, and stem seals, plus they’re magnafluxed and resurfaced to verify integrity and sealing. ARP Series 2000 or OptiTorque head studs and ARP connecting rod bolts are included standard, reinforcing the engine’s ability to withstand elevated cylinder pressures and heat cycles. Improved gasket sealing methods are used in known trouble spots to combat common 6.0L leak points. It’s built with the same advanced Rottler machining equipment found in high-end engine shops, ensuring the kind of precision that sets DFC apart from basic reman outfits. This long block is ideal for Powerstroke owners who want a fresh, dependable platform to build on without diving into heavy modifications.
