Second will come the material posts, steel is better because it has a fatigue limit and aluminum just keeps getting weaker until it breaks. That's true, but there are hundreds of thousands of aluminum roller rockers on the street and breakage isn't a big problem until you start to get to solid roller cam spring levels. Third is the real issue, and that is cost. The sad fact is that if your roller rockers don't cost a lot they will probably be crap. The number one issue with rockers that I have noticed for the last six years or so is if you try to cheap out on a rocker set it will fail and you will be hurt. So spend the $400 and up and buy the decent rockers the first time. At that price level material doesn't matter. Harland Sharp has a huge following on the board, and Hughes has many satisfied customers as well. Then there are Crane and Comp. There are others as well, but none of them have "pro" in their name.

R. What he said is right on....don't buy cheap quality rockers. The only pretty low cost rocker I would even consider would be a set of ductile iron ISKY or Crane rockers.

Thanks What engine.... for the low spring pressure you would be normally running on a hyd roller either steel or alum will work fine... as to cheap rockers... well thats something that can bite you

I run T&D on all my junk... not cheap but very good quality but all my current stuff runs high spring pressures

They are bushed at the shaft. Personally, for a street motor, I'd stay away from Aluminum or needle bearings at the shafts. http://store.speedmaster79.com/p-2477-mo...set-shafts.aspx LemonWedge - Street heavy / Strip ready - 11.07 @ 120

In my opinion there is nothing to be afraid of using aluminum rockers in a street motor- you just need to be sure you spend the money on the good ones. When I bought my Hughes rockers, my spring pressure was only around #375 opened, and the motor was a junkyard heap- I spent my money on rockers though as I knew a failure there would cost a whole lot more then just a rocker.
