Engineered for serious performance enthusiasts, these rocker arms are constructed from durable 8620 chromemoly steel, providing exceptional resistance to flexing and ensuring maximum camshaft lift. The advanced design features roller tips that minimize friction, contributing to smoother operation and increased power. Combined with a stiff construction and superior ratio accuracy, these Magnum roller rockers deliver more effective valve lift. This set is ideal for performance applications where the open spring pressure is less than 350 lbs. The package includes sixteen rocker arms, nuts, and spacers to complete the installation. Key features include a 1.72 ratio, 7/16" stud size, and the use of 8620 chromemoly steel for enhanced durability and performance. Installation notes indicate that studs are not included with this set, and it is designed for engines with an open spring pressure under 350 lbs. The product is explicitly listed for specific Mustang years including 1968 through 1973. This set is recommended for performance applications seeking a horsepower increase of 15-30 HP over stock rocker arms.
