You'll notice the difference with less friction

These Rollar rocker arms are a great way to get a reasonable price for mid-to-high range performance gains on smooth engines. I built the 2nd set of this type, I have a great product. ! Too bad there were stickers

Pros
  • Reduces internal friction in the valve train
Cons
  • Little things
