Complete International/Navistar Coverage

DT466 & DT466E Engine Solutions

The International/Navistar DT466 is one of the most iconic and widely used diesel engines in the trucking industry. Known for its durability and ease of maintenance, this inline-six, 7.6L engine has been a staple in medium-duty trucks, buses, and industrial equipment for decades. The DT466 is widely regarded as one of the most dependable and easy-to-service diesel engines in the industry. Unlike many modern engines, the DT466 is wet-sleeve, meaning it can be rebuilt multiple times without needing to replace the engine block.

MaxxForce Engine Family

The DT466 is produced today by International/Navistar under the model designation “MaxxForce DT”. International/Navistar rebranded the DT466E as the MaxxForce DT starting with 2008 models. MaxxForce DT: 7.6 L (466 cu in) displacement, bore x stroke 4.59 in × 4.68 in with horsepower ratings from 210–300 hp. We carry comprehensive parts for all MaxxForce engines, including MaxxForce 7, MaxxForce 9, MaxxForce 11, MaxxForce 13, and MaxxForce 15.
