Performance Racing Warehouse (PRW) offers several valvetrain upgrades engineered to work with the higher loads typically experienced when using a performance camshaft. PRW is known for offering great value on branded components you can trust.

Diesel Army: HiPo Rocker System Project DeadSpool To Get A Valvetrain Upgrade

Diesel Army has a new article up about our Dodge Cummins Pedestal Rocker System.  Here’s a snippet:


In my honest opinion, in all of the upgrades available for diesel engines, rocker arms are overlooked. We know they are the bridge between the valves and the pushrods of an engine, but other than that, they get used for valve adjustment and we move on. When you take something like Project Deadspool, something that is constantly abused, valve adjustment should be maintained more often.

Just recently, I had the valve cover off of the engine at a race for a valve adjustment and I was noticing some noise during idle and even at open throttle. I was hoping this could cure it and once inside, I discovered that some of the valves have been adjusted way too tight and some of the plastic caps that separate the rocker and the bridge were broken.
