Twin-Cam 88® Camshafts - Rocker arms

Bushing Roller Tip Rocker Arms Crane roller tip rocker arms have a bushing fulcrum for long term performance and reliability. These rocker arms use the original equipment rocker arm shafts. Made from 4140 alloy steel, precision investment cast for greater strength, truer rocker arm ratio, and improved rocker geometry. Also, our exclusive oil metering system fully lubricates the fulcrum and roller tip for cooler, smoother operation. These rocker arms fit with no machining, making them easy to install. This kit contains four premium rocker arms that install on your original rocker shafts.

The Strongest, Most Durable Needle Bearing Roller Rocker Tip Available! Our rocker arm design has the strongest cyclical strength available. This rocker arm reduces the friction in the valve train, thereby increasing acceleration and engine RPM. The roller tip reduces valve guide wear and galling of the valve stem. The needle bearings in the fulcrum are pressure fed with engine oil for longevity. The body is constructed from a 4140 grade steel investment casting. The ratio of these rockers is accurate to our most stringent standards and will balance the valve train so your motor produces the maximum amount of power. This kit contains new shafts, easy instructions and assembly lubricants. There is no machining required to install. These rockers are a must for any high output motor. • Improved Design Provides 52% Increase in Total Bearing Contact Area.
