Slant 6 Roller Rocker Arm Vendor(s)

I agree with Hyper-Pak. If you don't turn your six above 5500-6000 RPM the roller tipped rockers are not a necessity even though they have some advantages over stock. However on a higher revving engine like a 170 CID they are very beneficial for adding durability. I broke many stock rockers on the underside where the load bearing ring was tack welded to the stamped rocker body. I finally fully welded the circumference of the ring on both sides and this stopped most (not all) of my problems with breakage. And while what I did is a workable solution it is not the end all to the broken rocker dilemma like a quality set of billet roller tipped rockers should be. Nothing more frustrating than trying to fix broken rockers between rounds at bracket event !!
