Banks R866SC
6.6L Supercharged Diesel Turn-Key Engine (600-650 horsepower)
The all-new Banks R866SC supercharged 6.6L diesel engine delivers impressive horsepower, torque, and lightning-fast response with military-grade durability.
Banks engines undergo initial assembly on the production line at DMAX LTD’s Moraine, Ohio engine plant where dozens of Banks proprietary parts are seamlessly integrated. These all-new engines are transported to Banks’ Azusa, California engine plant for final assembly. Each engine is hand-built and rigorously tested by a single highly skilled engineer. These are not remanufactured. All Banks engines are 100% new.
Although they share similar architecture with Duramax L5P engines found in GM’s popular late-model pickup trucks, Banks engines are wildly different. No other diesel crate engine compares.
