Fully Running 5.9L Long block

The 5.9L Cummins is a highly revered engine known for powering some of the most rugged and reliable trucks. Choate Engineering takes it to the next level with their 5.9L Full Running Workhorse. The 5.9L Workhorse Long Block was built for those who need the capability to regularly tow heavy loads and handle tough jobs. Featuring several excellent upgrades over the Daily Driver model, including O-Ringed Heads, Billet Flex Plate, Coated, Fly Cut and Delipped Pistons, Stage 2 Cam, Chromoly Pushrods, and Welded Cam Gear. The Choate Engineering 5.9L Workhorse Long Block is ready to handle the toughest jobs.

Fully Built for Reliability and Performance

Choate Engineering engineers this heavy-duty Long Block engine to offer a significant leap in reliability and durability over the OE 5.9L. Featuring CNC blueprint machining, this engine exhibits incredibly precise engineering. Choate Engineering utilizes CNC blueprinting to line hone the crankshaft, aligning it precisely with the engine block and ensuring frictionless operation. The 5.9L Workhorse Long Block features new head gaskets, injector cups, freeze plugs, valve guides and seals, grind valves, and O-ring heads. Choate's 5.9L Workhorse Long Block is also fully balanced.

Furthermore, Choate Engineering addresses common issues with the OE 5.9L to ensure they do not occur with their 5.9L Workhorse Long Block. In the OE 5.9L, valve seats may fallout, contacting the piston which causes catastrophic failure. To remedy this, Choate machines oversized valve seats with a creased press-fit area. Another prevalent issue is the blowout of stamped gallery plugs in the heads, leading to a mixture of oil and coolant and destroying bearings. Choate addresses this by threading the head and using threaded plugs in their 5.9L to prevent such occurrences. Additionally, freeze plugs in the OE block may blow out, potentially leaving the engine stranded on the roadside or, at worst, with severe overheating requiring remanufacturing. To mitigate this, Choate includes billet freeze plugs that are blowout-proof. The 5.9L Workhorse Long Block by Choate Engineering is the ultimate 5.9L Cummins and is ready to power through the toughest jobs.
