Photos show rockers before trunnion rebuild. So you can see there real GM rocker arms. They will be switched out when purchased. LS1 style non offset straight rocker arms with upgraded Trunnions. The Trunnions are brand new and haven't been installed at all on any engine. These are genuine GM rockers that were sourced from low mileage engines. Not the Chinese knock offs that break. Usually pulled off for shaft mounted rockers. Complete ready to bolt on to your engine.
