FAQ
WILL THIS FIT MY 1998.5–2018 RAM 2500/3500 CUMMINS?
Yes – 4995602 is the correct OEM rocker lever assembly for 24-valve 5.9L and 6.7L engines in 1998.5–2018 Ram 2500/3500 trucks, including VP44 and common-rail applications. Always confirm via VIN/ESN if your engine has been swapped or heavily modified.
HOW MANY ROCKER LEVER ASSEMBLIES DO I NEED PER ENGINE?
This part is sold individually. Each 24-valve Cummins uses six (6) complete rocker lever assemblies to cover all intake and exhaust valves on the cylinder head.
IS THIS ROCKER LEVER FOR INTAKE OR EXHAUST VALVES?
The 4995602 assembly is used on both intake and exhaust positions on 24-valve ISB engines. There is no separate intake vs. exhaust part number for standard automotive applications.
WHAT ELSE SHOULD I REPLACE WHEN INSTALLING NEW ROCKER ASSEMBLIES?
For best results, inspect and replace the valve bridges and sealing components at the same time. We recommend pairing this part with CUMMINS 3943626 valve crossheads , plus fresh rocker box and valve cover gaskets: CUMMINS 3963379 and CUMMINS 3954324 .
DO I NEED TO SET VALVE LASH AFTER INSTALLING 4995602?
Yes. After bolting the new rocker assemblies in place and torquing to spec, perform a full valve lash adjustment following Cummins procedures. Re-check lash after the first heat cycle for long-term stability and quiet operation.
IS THIS A GENUINE CUMMINS PART OR AFTERMARKET?
This listing is for a genuine Cummins 4995602 rocker lever assembly supplied by CPP Diesel. It is the same style used in OEM service and late-model production applications, not a generic offshore copy.

Good Rocker Arms
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.

Good solid quality
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.

Works Perfect!
Great product. Cummins produces only the best. Installed easily on my 2007.5 6.7. Replaced all six---as suggested.

6.7L design works on older engines
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.
