For highly modified GM Ecotec engines built for high performance race applications, Jesel has developed an overhead cam follower designed to greatly increase reliability over the stamped steel OEM followers. The Jesel follower is easily capable of handling the added stresses resulting from the increase of cylinder pressure seen in turbo-charged or nitrous applications.
These heat-treated CNC machined steel followers feature a .480” diameter needle bearing valve tip roller to reduce valve tip scuffing and wear. To keep proper valve tip to follower alignment, the valve tip is shrouded in a .240” wide pocket which guides the follower and prevents disengagement from the valve. The valve tip nose roller is nested into a patented .700” diameter needle bearing camshaft roller which further frees up horsepower. Along with the reduced friction and added strength, another feature unique to our cam followers is what we call our Tail-Hook pivot ball receiver. The Tail-Hook design features a special contoured pocket to keep the follower from losing contact and disengaging with the pivot ball at high RPM. Jesel’s OHC follower for the Ecotec engine is available for an OEM style lash post or Jesel’s Adjustable Solid Lash Post.
Jesel has designed these adjustable solid lash posts to work in conjunction with our overhead cam followers. Ford and GM heat-treated, precision machined posts are supplied with an assortment of shims to adjust for proper valve lash. The tip of this post is designed to stay engaged into the body of the cam follower. This lash post is available with extended tips for small base circle cams.
Esslinger posts feature a 5/8-24 x hex nut with a 1.125” diameter flange to easily and securely set valve lash.
