PRO STEEL SERIES SHAFT ROCKERS

J2S KIT

TFS 245 CC GM LS1, 1.70 IN/ 1.70 EX

CUP ADJ #3619,K2S-SP2526-7070

Through extensive engineering and FEA analysis, Jesel has designed a steel bodied rocker with less deflection and a better moment of inertia than similar aluminum rockers. These advancements in rocker design allow engine builders the opportunity to develop a more aggressive cam profile and valvetrain package.

The rocker geometry is designed to minimize roller movement on the valve tip. Each rocker body is manufactured from premium billet steel alloy and undergoes a through hardened heat treating process for durability. All of the steel components are processed with REM/ISF® Isotropic Superfinish to remove asperities inherent in the manufacturing process and to safely remove microscopic peaks, greatly reducing points at which stress fractures can begin.

Fits solid roller TFS cathedral port heads using longer than stock valves.  

Requires drilling and tapping the rocker bolt holes for 7/16-14 holes.
