    Crane Cams Energizer Roller Rocker Arms feature a die formed aluminum body with needle bearing fulcrum and roller tip. The needle bearing fulcrum and roller tip reduces friction, lowers engine oil temperature, improves response, increases HP and RPM. Aerospace vacuum die-formed aluminum main body offers extreme strength and light weight. Great for street and moderate race use.

    Die-formed aluminum body is larger than stock, may require modifications to stock valve covers for clearance.

    Features:
  • Die-Formed Cast Aluminum
  • CNC Machined
  • Heavy-Duty Precision Ground Steel Needle Bearings
  • Heat-Treated Roller Tips
  • For Use With Valve Springs Up To 450 lbs Open Pressure
