COMP Cams developed its own trunion upgrade kit that addresses the stock trunion problems. The upgraded trunion fits inside the rocker arm and has grooves for c-clips at each end that prevent the walking issue. This not only adds strength to the rock arm, but it also allows it to maintain proper alignment and do its job correctly.
If you think installing this trunion upgrade kit requires the assistance of a machine shop, you better think again. In this video from COMP Cams, you can see just how easy of a project this is to do at home. You just need some basic hand tools and a vice to upgrade the trunions on your LS engine so you can add plenty of horsepower.Article Sources
