Mack E7 Used Diesel Engine

Mack E7 Used Diesel Engine


We offer a variety of Mack E7 used diesel engines that fit heavy duty on-highway class 8 trucks, transit buses, dump trucks and refuse applications. The Mack E7 debuted in 1988 replacing the long standing E6 which reigned supreme for over 20 years. The Mack E7 would go on to be a top seller and consumer favorite for their reliability and low end torque. Later versions of the Mack E7 included the ASET and Electronic E-Tech Versions which went up to 465 HP.

Our used Mack E7 engines are all thoroughly inspected and test run to ensure the quality of the components, this especially is important with the EGR and Turbocharger to ensure excess soot doesn’t clog the systems. The majority of our good used E7 runners are around 275-300 HP and are the 11GBA Serial Prefix.
