ATK Engines Replacement 4.0L I-6 Engine Reviews

Logan H.

My mechanic (Jeep specialist) was impressed with the quality of the engine, especially for the price. The engine also shipped way faster than expected. So far I've got about 1,000 miles on it, starts up instantly and runs smooth. Very happy with everything considering other shops/engine builders were quoting me 12+ weeks for a replacement engine.
