SBC Roller Rocker Arm Set 1.5 Ratio 3/8 Stud

Harland Sharp SD1001 SBC 3/8" stud mount roller diamond rocker arms with a 1.5 ratio, designed for Small Block Chevy 262-400 heads. These rocker arms clear up to 1.450" springs and retainers and fit center bolt valve covers, offering improved clearance for valve covers and stud girdles. Their lightweight design reduces moving mass by up to 100 grams, enhancing valvetrain efficiency. For late model LT1/LT4 self-aligning cylinder heads, pushrod guide plates are required. For springs larger than 1.450" with a 3/8" rocker stud, the Heavy Duty 3/8 series (Part # CSP-SH1001) is recommended. Each set includes 16 orange anodized aluminum rocker arms with polylock fasteners.
