Precision-built and fully balanced, this engine ensures smooth operation and reliability. It's the ideal choice for those needing a hard-working engine that can tackle any tough job effortlessly. The 6.6L Workhorse Short Block is a durable reworking of the already legendary 6.6L Duramax. Legendary 6.6L Perfected Choate Engineering went beyond simply building a standard replacement for the 6.6L Duramax engine; they elevated it to new heights. With robust chromoly pistons, a stage 2 camshaft, O-ringed heads, coated, flycut, and delipped pistons, along with head studs, a fresh flex plate, and harmonic balancer, the 6.6L Short Block Workhorse offers enhanced durability and performance compared to the original equipment. Choate Engineering solves potential issues that the OE 6.6L had. One issue is the pistons being a failure point, the wrist pin bushings fail, thus Choate updated the pistons to be a press in bushing rather than using a wrist pin. Choate Engineering's 6.6L Workhorse Short Block is an expertly upgraded 6.6L ready to perform in any task.
