First and foremost, please don’t waste your money on inferior aluminum roller rocker arms. You will get what you pay for when it comes to the type and quality of aluminum being used in the manufacturing process. In addition, bearing quality is also horrible in these offshore sets being manufactured in China. I see roller rocker arms (and many other auto parts) being made from cast aluminum for sale all over the internet. Never put cast aluminum roller rocker arms inside your engine. It’s a recipe for disaster. The aluminum that is being used from Asia is of inferior quality. Unfortunately, there are some US based companies using it to save money.
The photos below are from 2 aluminum roller rocker arms cut in half. The rocker on the left shows the voids and areas where stress cracks will appear. This rocker arm is cheap and readily available on the internet. The photo on the right is from a aluminum roller rocker arm that we just pulled off the CNC machine here at Scorpion. Both are magnified under a microscope.

You may notice that Scorpion doesn’t do a lot of advertising. Advertising, Sponsorships, Banners, etc., just cause other companies to charge you more to cover their costs.
