Hey guys. Been a while since I've posted. Last 4.0 I rebuilt I used Ford parts. Still going strong. I recently brought a rattle bomb explorer for next to nothing and ended up taking the engine out and decided to use a cheaper kit than the $400 ford one. I went with a brand called DNJ Engine Components off of the website partsology.com. I paired that kit with Ford hydraulic tensioners that I had laying around the garage. I'm at 30k miles on it since the cassette replacement and I haven't heard a single sound. Im sold on the DNJ kit.
Thanks.
