“Hello Everyone!

My experience with J&K has been nothing short of amazing. I found them after looking online. I had suffered a catastrophic failure when a lifter came apart, and as anyone who knows about a Powerstroke, it doesn’t take long for the whole system to be affected. My local dealer had just told me, replacing my motor with a new one would run me about $18,000.”

“After talking with Jack, explaining what actually happened, he gave me the reasons why. Jack & Keith have 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, Keith & 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.”
