I purchased these as non Chinese manufactured roller rockers, I expected to get Scorpions which I've heard good things about but I got this package. I've debated a few times about putting them on and will have the intake off the motor soon and wanted to know if anyone can help identify these and make a call on there quality.

 

if you cant return them what have you got to lose?they look alot like mine (speed pro?)but i dont remember the brand name....i will look it up and get back to you...that aside ive had no problems with them after a year and a half of hard use...tao

 

I'm really only concerned with one of them breaking and wiping out a lifter, cam, or even the bottom end. I had heard horror stories about the cheapo roller rockers splitting in half or losting there rollers down into the engine. This is probably being over cautious but I just wanted to see if i could find out if these are the said cheapo's or if they're truly decently made units. I know they're not the proform RR's that everyone says to avoid and I've really never seen any made like this, they're very similar to the Scorpions that i thought I was purchasing. I'm thinking they may even be them but stamped differently for the company that was selling them.

 

Got a machine shop nearby? Take them over and see what they have to say, most of the time they can give you some insight.
