Jesel Pro-Steel Rockers for 6.7L Powerstroke

Jesel Valvetrain Innovation's new Pro-Steel Rocker system will be available exclusively through Kill Devil Diesel and its dealers.

Jesel and Kill Devil Diesel have together introduced the world’s first and only aftermarket valvetrain system for the 6.7L Powerstroke. Jesel Valvetrain Innovation’s new Pro-Steel Rocker system will be available exclusively through Kill Devil Diesel and its dealers.

The engineers at Jesel have ensured that the Pro-Steel Rocker System for the 6.7L Powerstroke will handle the immense cylinder pressures of 3000+ hp competition engines and are strong enough to endure a grueling 24-hour road race or Drag Week-style events with miles to spare. Through extensive engineering and FEA analysis, Jesel has designed a steel-bodied rocker with less deflection and better moment of inertia than factory, aluminum, or any other rockers on the market. These advancements allow engine builders the opportunity to develop a more aggressive cam profile by utilizing a more stable valvetrain package, which allows the engine to make more power, higher in the rpm range.

The new rocker kit includes left and right rocker stands, 16 shaft-mounted, forged-steel rockers, 16 tool-steel valve bridges, oil plugs, all secured with ARP hardware.

Combine these rockers with the world’s first solid lifter insert to work in conjunction with factory lifter bodies for next level performance. For more info: Kill Devil Diesel
