New at Summit Racing: Get More Lift and Valve Control with Scorpion Endurance Series Rocker Arms
Tallmadge, OH (PRWEB) November 03, 2014 -- Add some extra valve lift and valvetrain control with a set of Scorpion Endurance Series Roller Rocker Arms. The rockers’ higher-than-stock ratio helps increase overall valve lift, which aids airflow and combustion efficiency. That means more horsepower.
The Endurance Series rocker arms are full rollers with CNC machined aluminum bodies, so they help reduce valvetrain friction and weight—and that further improves horsepower potential.
