Excellent and friendly service. Purchase was easy and fast. Quality engine build. I have 10,000 miles on it so far and it is running great. I travel 120 miles a day back and forth to work with no issues. Highly recommended!

Ordered a stage 2 6.0 for my 04, we had a hiccup or two thanks to a couple of my previous modifications but J&K took care of everything and pretty quick, motor has a lot more power and was reasonably priced, little motor’s sure gonna get put through the paces here

I am very satisfied with my 6.7 power stroke long block from J&K. I have put about 3k miles on it so far and it’s running great. I highly recommend this Company. Great customer service.
