I like these rocker arms. They seem to be great quality. I had no issue with them on my 2001. The only thing that I did not like is that they are made in India, they are not USA like Factory. Other than that they are great and work just as they are intended to.
Great deal on excellent rocker arms only wish they were oiled. I ended up putting everything in a five gallon bucket full of used oil from the last change and let them sit for 24 hours. Haven’t had a problem and takes 20 minutes to install and 30 minutes to lash.
Great product. Cummins produces only the best. Installed easily on my 2007.5 6.7. Replaced all six---as suggested.
I had a broken plastic retainer on the elephants foot of my #5 intake and exhaust rockers on my '05. This design is definitely stronger. CPP shipped it fast and it was a great deal. My only complaint is that the plastic retainer on the older design gives you a place to hook your fingernail and slide in the feeler to set lash. This new design is a bit tricky to get lash set sometimes. Even so, I'm wondering why I didn't just go ahead and replace all 6 while I was in there.
