This kit replaces the problematic factory hydraulic roller lifters and camshaft to a reliable flat tappet. It is 49 state certified. We are confident it would pass CARB testing, but we don't do business in California. This kit will fit and is emission certified for all Ram 2019-2024 2500 and 3500 diesels not in California.
It comes with
- 178/208 Forged camshaft
- DLC coated steel tappets
- upgraded pushrods
- Adjustable rocker arms with DLC coated trunnions
