Jesel OHC Follower Features

  • .520” diameter needle bearing nose roller ensures smooth and precise valve tip movement, while alignment is maintained by shrouding the valve tip with the follower body.

  • .520” needle bearing nose roller eliminates valve tip scuffing along with a .900” diameter needle bearing cam roller to gently transfer cam lobe lift into valve lift.

  • .480” diameter needle bearing nose roller reduces valve tip scuffing and wear. The valve tip sits in a .240” wide pocket, preventing valve disengagement.

  • GM Ecotec valve tip nose roller is nested into a patented .700” diameter needle bearing camshaft roller which reduces friction and frees up horsepower.

  • Heat treated, CNC machined steel follower bodies greatly improve reliability over inferior OEM followers.

  • Jesel OHC followers can be quickly and conveniently installed or removed, without the need for camshaft disassembly

  • Engineered to endure the extreme conditions and additional stresses generated by turbocharged or nitrous applications.

  • Tail-Hook receiver ensures the follower remains in contact with the pivot ball even at high RPMs, enhancing valvetrain stability.

OHC Follower Lash Post Adjusters

Jesel has designed adjustable solid lash posts to work in conjunction with our OHC followers. The tip of these precision machined posts are designed to stay engaged into the body of the follower and come with an assortment of shims for proper valve lash. Available with extended tips for small base circle cams.

Esslinger posts feature a 5/8-24 hex nut with a 1.125” diameter flange to easily and securely set valve lash.
