When it comes to rocker arms, you’ll see that they come in three basic flavors: stud-mount, pedestal-mount, and shaft-mount.
While there are pros and cons of each rocker arm design, you should absolutely know the distinctions between each one before you select the best rocker arms for your engine and cylinder head application.
The good news is, the valvetrain experts over at Scorpion Racing Products have put together this in-depth video that’ll explain the benefits of each of the three rocker arm styles. The video will also give you a good idea where you’ll find each one too.
And the even better news is, that once you watch the video, you’ll realize that there are very good use cases for each design, so it’ll start getting really clear which rockers will work best inside your cylinder heads.
Like so many videos we get from the Scorpion folks, this one doesn’t skimp on the details. The segment runs close to ten minutes long, so it’s crammed with a ton of valuable valvetrain insight direct from the techs and engineers who work in and around cylinder heads on a daily basis.
