1.5 Ratio Roller Rocker Arm Set

The JEGS 555-20921 Stainless Steel Roller Rocker Arms are engineered for Small Block Chevy applications, offering a 1.5 ratio and designed for 3/8 inch studs. These full roller rocker arms feature oversized full needle bearing trunnions, aiming to boost horsepower, enhance responsiveness, and improve durability. Constructed from stainless steel, these rocker arms are built for longevity and performance. The set includes 16 rocker arms and 16 studs, ready for installation with polylock nuts. One snippet mentioned they measure approximately 85 thousandths of an inch wider than some other JEGS rockers, which might be a consideration for valve cover clearance with aftermarket heads like Edelbrock.
