Crower is continually developing shaft rocker systems for the new "hot" cylinder heads. Each Crower Shaft Rocker setup is impeccably designed and produced to maximize valve train rigidity and accuracy. We utilize the longest arm length possible for each application, resulting in minimal rocker tip travel. This results in less frictional power loss as well as accommodating larger diameter valve springs. Crower Shaft Rocker Setups allow for the quickest "at the track" valve train modifications around.  Any change that requires rocker removal can be performed without concern for absolute accuracy upon reassembly.

Crower Shaft Rockers are available in three material choices:

• Stainless Steel: Sustained high temperature has little affect on the strength, corrosion resistance or mechanical properties of stainless, which results in significantly longer life expectancy than inferior cast steel rocker arms on the market today. Longevity, precision valve response and accuracy make this a perennial favorite of dirt late model and marine endurance competitors. 

•Billet Aluminum: This budget minded shaft rocker arm setup utilizes all of the premium stands and hardware of our Stainless & Billet setups.

•Steel Billet: This is the latest addition to the Crower Shaft Rocker line. The Crower Steel Billet Shaft Rocker arm is designed for extreme spring pressure applications and hard to fit cylinder heads.
