Crane Cams 11747-1 - Crane Cams Energizer Roller Rocker Arms Details
Chevrolet
Increased ratio with enlarged stud diameter. The 1988-99 engines equipped with self-aligning rocker arms require the installation of pushrod guideplates (and 99157-16 7/16" rocker arm studs, if applicable) and appropriate heat treated pushrods in order for these rocker arms to function properly. Valve cover clearence must also be checked. Not suitable for use with center-bolt valve covers.
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.
