Official Release:

Jesel Valvetrain Innovation has just completed a Sportsman Series rocker kit for the GM LS3/L76/L92 cylinder heads. This kit features a precision-machined steel rocker stand that attaches to the head without any type of cylinder-head modifications. Rocker geometry has been engineered using the stock length valve and spring package for a simple bolt-on-and-go installation. The solid body 1.465 pivot length rocker bodies are manufactured from a custom-blended 2024 aluminum alloy and are treated to a standard shot-peen finish. Rocker tail profiling for added valve cover clearance, cup style tool steel adjuster and a mechanically retained nose roller assembly are also included as standard features. The rockers are available in either a 1.70, 1.75 or 1.80 ratios.
