That’s the first PF aluminum rockers I’ve seen that are needle bearings. I read the complaints. All 7 of them. Most said they are too tight on the shaft. Maybe so, but who fits any rocker with out measuring it first? I don’t. I had to hone every single W2 rocker I had. Even the bushed ductil iron rockers. I don’t run them nearly as tight as everyone else seems to.
There was also complaints of breaking them. I’d bet everything I have, and some stuff I don’t have, not one of those clowns corrected the geometry. I’d bet they don’t even know what that means. To use a roller tip rocker and not correct the geometry is asking for a failure.
I broke some T&D rockers. It was because the customer didn’t want to spend the money to correct the geometry. He did AFTER they failed.
I may not run those rockers with 280 or more on the seat, but for 99% of what guys do on here, they’ll be fine.
I almost forgot...the other rocker killer is guys wanting to run 20 PSI oil pressure at idle. That will kill any rocker that doesn’t have needle bearings in them. The higher the spring load, the more critical idle oil pressure becomes. It doesn’t take long for a rocker not getting oil before it grabs the shaft and fails.
That’s not the rocker arms fault.
