New from Livernois – the Powerstorm HEMI Rocker Bar Systems. These rocker bar systems are made from CNC machined billet aluminum to increase valvetrain stability. See more details below.
Livernois Motorsports’ new Powerstorm HEMI Rocker Bar Systems increase valvetrain stability for 5.7L, 6.1L and 6.4L HEMI engines, supporting tuning and engine enhancements that increase engine speed. One system is designed specifically for 5.7L and 6.1L, while the other system is for 6.4L engines.
Crafted from CNC-machined billet 6061 aluminum and extruded round 6061 aluminum, the lightweight rocker bar systems help stabilize the HEMI engines’ unique valvetrain at higher rpm, enhancing durability and reducing friction – particularly with tuned engine combinations and power adders such as superchargers or nitrous oxide. These bolt-on components simply replace the engines’ original rocker bars.
“A HEMI engine is designed to produce serious horsepower and torque, which can impact the stability of the valvetrain. At Livernois, we created our Powerstorm Chrysler HEMI Rocker Bar Systems to increase that stability which then allows for drivers to achieve higher speeds with greater safety,” said Tom Millen, General Manager for Livernois Motorsports. “We were first to market with these systems nearly ten years ago, and they’re still a popular product.”
Livernois’ HEMI rocker bar systems include upgraded rocker bar shafts, billet aluminum rocker bars, fastened with ARP bolts, shaft washers, shaft collars and adjustable clamps for setting the rocker position. The shafts are made of 4130 chromoly steel and offer increased wall thickness for greater strength. Together, each system weighs about 15 pounds, saving about three pounds from the stock systems.
Livernois offers the rocker bar systems individually, but can assemble them into a complete cylinder head as well. Installation is available at the Livernois’ Michigan facility.
