Precision Engineered to Maximize Durability and Reliability

Choate Engineering has applied their precision craftsmanship not only to precisely engineer this short block engine but also to improve upon the OE. Featuring full CNC blueprint machining, this engine boasts incredibly precise engineering. Choate uses CNC blueprinting to line hone the crankshaft to align it precisely with the engine block, ensuring frictionless operation. They bore the block back to the crankshaft centerline and hone it to an RA13 finish to further reduce friction. The cylinder block is surfaced to a finish of RA30 or lower to meet or exceed factory specifications in flatness and smoothness for the block-to-head sealing surface. Choate also includes a new rear main seal, new bed seals, a new rear cover gasket, a pickup tube O-ring, and a rear cover. Choate's 5.9L Workhorse Short Block is fully balanced and ready to power your heavy-duty tasks.

Choate also ensures that common issues with the OE 5.9L won't happen with their 5.9L Workhorse Short Block. In the OE 5.9L, the valve seats fallout contacting the piston and cause catastrophic failure. Choate machines oversize valve seats with a creased press-fit area to remedy this issue. Another issue that plagues the OE is the stamped gallery plugs in the heads blow out causing a mixture of oil and coolant, destroying the bearings. Choate threads the head and uses threaded plugs to ensure the issue is not present in their 5.9L. Freeze plugs in the OE block blow out leaving you stranded on the side of the road, at worst, with a severely overheated engine in need of remanufacturing, to fix this Choate includes billet freeze plugs that are blowout-proof. It's clear that the 5.9L Workhorse Short Block by Choate is engineered to be reliable and rugged, and it won't let you down.
