Proform Engine Rocker Arm - 66878P

PROFORM Super Street Aluminum Roller Rockers have a beautiful anodized finish, extremely tight tolerances, and upgraded cage bearings. This single arm is a replacement for the set fitting Ford S/B aluminum cylinder heads, pedestal mount '77-'94, 302HO and 351W hydraulic and roller cams. Rid your engine of internal friction with roller-tipped rocker arms. The race-proven full needle bearing, fulcrum, and roller tip not only unleash horsepower, they also lengthen valve train component life and reduce wear and tear on valve stem tips. Precision machined to insure consistency and ratio accuracy.

Note: Roller Rocker Arm for 1.7 Ratio 5/16 Stud
