Die Formed Aluminum Body with Needle Bearing Fulcrum and Roller Tip

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, and may require modifications to stock valve covers for clearance.

Note: Cannot be used with late Chevy 90° V-6 and small-block V-8 ''Center Bolt'' valve covers. Will not fit 90° V-6 or small-block V-8 self-aligning 88-99 heads.
