Procomp rockers???

I ran aluminum off brand 'ohio crank' rockers that have needle bearings, worked great.
I only had to retire one from too much side play, too much side play on ANY needle bearing rocker [HARLAND SHARP] will lead to race failure where the rollers eat into the race causing play and the race's outer edge to actually ride the shaft, but in my case it took years....
HOWEVER if you were to have the correct .010 side play that wouldn't happen and...there would be no way for any needle bearings to come out unless the shafts disintegrated and rocker body shattered.lol

Most people who have bad things to say about needle bearing rockers have never personally ran them.
