Superfinished chilled iron camshaft follower sets are used in our high-end engine builds here  and sold to many other leading race engine builders. They're drilled to ensure better oil drainage and feature the lightweight design of our race followers. 
 
Each set is matched to within a gram, with the correct base radius design to allow rotation in use.
 
The superfinishing process results in increased durability and is the ultimate upgrade for when the race regulations allow.  
 
High quality steel pushrods are another highly recommended upgrade on a race engine build.
