Mopar Performance Roller Rockers

but an aluminum rocker without a bushing will work just fine.

Sorry, but I'll trust the first-hand reviews of the proform rockers we were talking about WELL before I go running them with 900 lbs over the nose at 8500. There's NO WAY I'd take that gamble. Way too many other decent rockers out there to take the chance with the cheapie proforms.
