ROCKER ARMS, DIE CAST ALUM SMALL BLOCK FORD 1.6 1 ST

from

$237.99
The COMP Cams High Energy Die-Cast Aluminum Roller Rocker Arms are new rocker arms from the valve train leader that have been designed for street and moderate race use. They feature a die-cast body created from aluminum with a needle bearing fulcrum and roller tip. The die-cast, larger than stock body offers the strength properties and light weight of aluminum while the specially engineered fulcrum and roller tip decrease friction and lower oil temperatures, thus improving response and horsepower.

Product Features:
  • Cost effective aluminum construction provides superior strength to weight ratio
  • Needle bearing fulcrum and roller tip reduce friction and lower oil temperatures for improved response and horsepower
  • Durable design increases valve lift while withstanding the rigors of moderate race use
  • Die-formed aluminum body is larger than stock, and may require modifications to stock valve covers for clearance.
