Jasper Engines & Transmissions, a remanufacturer of drivetrain components, is offering a remanufactured Caterpillar C7 common rail diesel engine.

The new Caterpillar C7 engine with ACERT technology -- available in horsepower ratings of 190 to 300 -- can now be ordered with Peterbilt's medium-duty Model 330 and low-cab-forward Model 320.

Caterpillar has introduced the next generation of the Cat C7.1 ACERT industrial engine, designed to meet U.S. EPA Tier 4 Final/Stage IV emission standards.
