Do you have firsthand use knowledge of these particular rocker arms?
I have asked the same exact same question as the OP on here before and have yet to hear from someone that has direct hands-on experience with the Pro-Comp rockers on a Mopar.
Yet that wasn't enough of a clue apparently.
I don't use bottom of the line tubes in my dirtbike tires, but I have no first hand experience with them either. :D
I can however tell you how many bikes I have waited for on the trail while they dealt with a flat from them.
