Crow Cams' stud-type stainless steel roller rockers offer an unbeatable combination of strength, rigidity and value for money.
With more aggressive cam profiles and heavier valve springs now common in street and race applications, the limitations of extruded alloy as a rocker material are clearly evident. The flex alloy rockers exhibit reduces valve lift and horsepower potential and the stresses can lead to arm failure.
These problems have lead to a move to steel rocker arms in the upper levels of motor sport and now the strength and stiffness of steel is within the budget of every performance head.
Crow Cams' new stainless steel stud type roller rockers offer virtually zero arm deflection for maximum valve lift and unrivalled resistance to arm breakage. The larger shafts and needle roller bearings also offer greater load capacity for high valve springs pressures.
Every set comes complete with poly locks for added value and simple, secure valve lash adjustments. Crow Cams' screw in studs and guide plates will be required to fit these rockers to many factory cylinder heads.
For more than 30 years, Crow Cams in Australia, have developed valve train products and developed unique camshafts. Crow Cams, work closely with the USA’s leading performance manufacturers to produce extremely high quality roller rockers that just look and perform epic.
REQUIRES 7/16" SCREW IN STUDS (CST100941) AND PUSHROD GUIDE PLATES (GP350) WHEN FITTED. CYLINDER HEAD MACHINING IS REQUIRED WHEN FITTING THESE ITEMS.
