Has anyone ever had any problems with any of the roller rockers out on the market today. I have heard of the snaprings on the sides of them busting off and causing some big time damage. Is this just a freak accident or is it common or what? I am on a tight budget and plan to just pick up a set of aluminum roller rockers from Jegs for 165.00. My concern is they to have the snap rings on the sides of them where the rocker pivots.
