Understanding the critical difference between a remanufactured diesel engine and a standard "rebuilt" unit is the first step toward ensuring the longevity of your vehicle. While a rebuilt engine is often a mere "patch job" where a technician simply tears down the block to replace only what is broken, a Choate Remanufactured Engine represents a complete engineering rebirth. We strip every engine to its core for thermal cleaning and utilize a precision machining process, meeting or exceeding original factory specifications. Rather than just replacing parts, we proactively upgrade the design to solve known factory defects, ensuring our engines are built better than new. For the educated consumer, the choice is clear: don't settle for a repair when you can invest in a high-performance diesel engine redesigned for ultimate durability and a second life on the road.

At Choate Engineering Performance, we believe that the heart of a high-performance diesel engine lies in the precision of its internal geometry, which is why we specialize in truly balanced rotational assemblies. Unlike mass-production facilities that rely on "stack tolerances" or factory-acceptable margins, we treat every crankshaft, rod, and piston as a single, cohesive unit. By utilizing state-of-the-art balancing equipment, we eliminate the harmonic vibrations that lead to premature bearing failure and engine fatigue. This meticulous attention to detail ensures that your engine doesn't just run—it operates with a level of smoothness and efficiency that reduces internal friction, maximizes horsepower, and significantly extends the life of the engine. Whether you are hauling heavy loads OTR or pushing limits in the field, our balanced assemblies provide the mechanical stability required for the most demanding environments.

At Choate Engineering Performance, we believe that true quality control can only be guaranteed when every critical process happens under our own roof. Our facility is equipped with advanced 4- and 5-axis CNC machining centers, flow benches, and precision testing equipment, allowing us to handle every stage of the remanufacturing process in-house. By keeping these specialized services on-site, we eliminate the risks associated with third-party outsourcing and ensure that every component is machined to our exacting tolerances. This hands-on approach gives us the total confidence that every engine shipping across the country has been scrutinized, tested, and verified to meet the highest level of mechanical integrity.

The Choate standard is defined by engineering out the weaknesses that the original manufacturers left behind. Every remanufactured diesel engine we produce is a "re-engineered" powerhouse, designed to solve notorious OEM design flaws that lead to catastrophic failures. From correcting cracked pistons in the Powerstroke 6.4L and bearing failures in the Cummins 6.7L to addressing broken Duramax crankshafts and frequent valve seat issues, we don’t just replace parts—we improve the platform. By combining precision balancing technology with upgraded component designs, we deliver an engine that is more reliable, more durable, and more efficient than the day it first rolled off the factory assembly line.

At Choate, we prioritize quality over quantity by choosing to focus on the precision of every individual build rather than the high-volume output of mass-production factories. We aren't interested in churning out hundreds of thousands of generic engines; instead, we invest the extra time required to do the job right, providing our customers with long-term savings through unmatched reliability and higher-grade components. By refusing to cut corners, we ensure your equipment stays in the field and out of the shop. Whether you are in forestry, construction, marine, oil and gas, stationary power, material handling, transportation, OTR, rail, fleet, or agriculture, let the Choate standard repower your business with an engine built to endure.
