Their specially engineered fulcrum and roller tip create far less friction than sliding factory models to lower oil temperatures, thus improving both response and horsepower. Snap rings are used to hold the trunion and bearings locked in place, and the simple, bolt-on design fits most popular muscle car applications. Polylocks included. High Energy Die Cast Aluminum Roller Rocker Arms are affordable and are available for most applications.

Features:

• Aluminum construction provides superior strength to weight ratio
• Needle bearing fulcrum & roller tip reduce friction & lower oil temps for improved performance
