These shaft-mount aluminum roller rockers are built for Big Block Chrysler B and RB engines. Bronze bushings give the rocker a low-friction pivot, with oil fed up through the shaft and under the bushing, while channels and holes in the bushing lubricate the pivot area. The roller tip reduces wear on the valve stem tips, the adjustable pushrod tips allow precise lash setting, and the kit includes 16 rockers, hardened shafts and hardware.
