I remember when PRW stainless rockers could be had for under $200 new, at the same time Crower Enduro were about $450.

In the long run you didn’t save anything because you had to buy something good later on.

Nowadays it’s easy to do research and see if cheap is actually good and sometimes it will be.

Do your research before pulling the trigger on parts that cost half or less than the more expensive ones. Right here on the forums there are plenty of failures reported on those PRW rockers so the information is there if you look.

In the stud mounted stuff, I have had good luck with the Crower SS rockers. Second in line would be the Comp. steel stuff although they have Chinese needle bearings. In aluminum body, Harlan Sharp is the only stud mounted rocker I would use. Although they do have failures, they have great customer service and promptly replace defects quickly with no questions or drama. I won a set of Scorpions in a drawing at PRI several years ago. I didn't install them. Traded them for some other stuff. Too many failures in multiple engine platforms. We have had at least half a dozen rocker arm failures on the dyno over the last 10 years. This is on many different engine platforms on student engines. In EVERY case it was pretty brightly colored aluminum body rollers from off shore suppliers. Pretty risky IMO.

Even on shaft systems, these cheap rockers are a danger. I did 2 mopar engines with Proform rockers. One LA motor, and one RB motor. BOTH had failures. Even with HFT cams and modest springs.
