Description
Experience superior power and efficiency with our high-quality Detroit DD15/DD13 Diesel Engines. We offer these advanced engines in both Long Block and Long Block Premium configurations, designed to meet the demanding requirements of heavy-duty on-highway trucks and coaches.
The DD15 and DD13 engines are renowned for their improved fuel economy and enhanced performance, making them a top choice for commercial fleets. A key feature of these engines is the APR (Anti-Polishing Ring) Cylinder Liner, which prevents carbon buildup on the piston top land, ensuring proper cylinder function, stable lube oil consumption, and reduced liner wear.
We supply DD15/DD13 engines across different generations:
- EPA 10 = Gen 2: These models feature an upgraded liner and head gasket to the APR style.
- EPA 10 GHG14 = Gen 3: These models come standard with the APR liner.

ENGINE TESTING
Every engine is machined using state-of-the-art equipment and assembled using precise and repeatable methods. All engine production follows documented lean manufacturing processes and principles to create consistent quality and dependable outcomes.
All Short Block, Long Block, and Long Block Premium are 100% Sim tested before shipment.
Complete Drop-In engines are 100% dyno tested before shipment. Computer controls ensure that each engine dyno test is conducted under standard, repeatable settings. Every engine is run through a warm-up cycle; three separate cruise segments simulating light, medium, and heavy throttle conditions; maximum torque and horsepower tests; both high and low idle tests; and a black light leak detection test with dyed oil, coolant, and fuel.
we’ve been delivering remanufactured engines for skid steer loaders for over 30 years—longer than any competitor in the industry. Our veteran machinists, many with decades of experience, follow engine-specific rebuild procedures to ensure consistent quality with every unit.
Each engine is carefully rebuilt to meet or exceed OEM specifications, using top-tier components and proven techniques. This is more than just a repair—it’s a full remanufacturing process designed to restore the engine to like-new condition.
Before shipping, every complete skid steer engine is dyno-tested for performance and reliability, so you can install with confidence.
