Comp Cams CO1621-16 CHRYSLER 383-440 1.5 Ultra Pro Magnum Shaft Roller Rockers

COMP Cams Pro Magnum shaft mount roller rocker arms combine the strength of 8650 chromoly steel and the weight savings of aluminum rockers.

COMP Cams took advantage of computer design to simulate the stresses that affect rockers under various operating loads. This allowed the engineers to lessen the rockers' mass at non-critical areas and strengthen the areas that take the most punishment. The results are rocker arms that are strong where they need to be and actually weigh 5 percent less at the valve than comparable aluminum rockers.

• Investment cast 8650 chromemoly body and arched, web - like design deliver increased strength and rigidity while reducing moment of inertia
• Unique black oxide exterior finish helps prevent corrosion, thus increasing durability
• Optimised retainer and valve spring clearances allow use of most diameter springs, retainers and +.050" locks without clearance or fitment issues
• Feature oversized trunions, precision - sorted needle bearings and hardened roller tips
