Yes! "Covid Country" rocker arms are cheaper, and there is a reason for that. They are cast aluminum. Ours are extruded billet material - far superior in strength and durability. But theirs are cheaper!
And another thing. Why do people insist on putting those @#*$ needle bearings on the shaft. That is an accident waiting to happen! With a mopar you have full engine oil pressure to the rockers -- just like the main and rod bearings and they don't have needle bearings. Why should the rockers? Ok, I know -- Chevy and Ford do it, monkey see, monkey do! And the Fords and Chevys only have a dribble oil system so I guess it makes sense, for them!
