Chevrolet Small Block Proform 3/8" Stud 1.5:1 & 1.6:1 Ratio Mixed Aluminum Roller Rocker Set

Rid your upper valve train of friction with these full-roller rocker arms. The race-proven 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 ensure consistency and ratio accuracy. Set includes a mixture of (8) 1.5:1 stock ratio arms and (8) 1.6:1 ratio arms to allow greater air flow on either the intake or exhaust ports, depending on your needs, for increased horse power and torque.

Fits Chevrolet small blocks through 1986 with 3/8" rocker studs. Set of 16 full roller rockers and 16 poly locks.

Easy installation requiring no special tools.

Note: Check for pushrod clearance and alignment, spring coil bind, piston-to-valve clearance and valve timing when modifying the valve train to exceed factory specs.
