      “J&K made me a strong 6.0 bored out and bullet proofed. Runs strong as hell. They have given me outstanding customer service, if you want a strong engine and personable customer service J&K will take great care of you.Thank you Jack!
      -Richard Redmond

      “Product is trustworthy sale, shipment and quality is excellent highly recommend”
      -Troy Toaldo | Plant Manager at Berks Can Company

      “After talking with Jack, explaining what actually happened, he gave me the reasons why. Jack put together a product that has my truck running better and smoother than new. The acceleration and torque is amazing to say the least, and if you use the programmer that they supply to you, it gets scary. I have put on 24,000 miles in the past year and have had not one issue, not one. You won’t be disappointed, and you will gain Jack, Zac & Debbie as friends.

      P.S. All said and done, transferring parts after cleaning, some new upgrades and new sensors attached to their product, I did it for around $11,000.”

      “I purchased an engine for j&k in April of 2013. I have put approximately 175,000 miles on it sense then. I have to say that I AM WE’LL SATISFIED with the performance and running of the new engine, I really didn’t want to purchase a new truck. So thank u to Mr. Jack for taken care of me. # happy 6.0 owner now.”
