Jims USA Roller Rocker Arms

JIMS Roller Rockers are designed to reduce friction in the valve train and provide more horsepower with less heat in the top end. Cast from 4340 chromoly steel and heat treated, JIMS Roller Rockers feature a 660 bronze bushing fit to .0007" to .0012", for the best wear resistance and oil control, along with a roller tip made from bearing grade material which reduces valve guide wear and valve tip galling. Other features include a segmented parabolic pushrod cup which reduces friction at pushrod ends and also puts the load on the outer perimeter of pushrod ends. Designed to work in conjunction with other JIMS valve train components.
