Edelbrock 1.5:1 Red Roller Rocker Arm for Small Block Chevy

For Small Block Chevy engines with 3/8” studs looking to polish up performance, this red roller rocker arm has got your back (77771). Edelbrock crafts this arm from lightweight, 7129-grade aluminum with a body that can accept up to 1.65” diameter springs. The body undergoes a meticulous CNC-machining process followed by micro-polishing and anodizing. Not only does this give it an accurate fitment and unmatched strength, but devilish good looks as well. Performance becomes smoother too because the trunnion race, roller pin, and roller tip all have a centerless ground.
