Performance and Design:
Manton engineers “I-Beam Rocker Arm” to meet the rigorous demands of racing applications. This design enhances strength, stiffness, stability, and reliability, making it ideal for high-abuse environments. The I-beam design has been trusted for decades, providing superior strength and stiffness for various applications, including bridges, buildings, and now rocker arms. Our roller tip I-beam rocker arm offers the highest strength-to-weight ratio. Made from high-grade billet steel and heat-treated for enhanced properties, each rocker arm features a nitride tool steel shaft to minimize breakage. The high-load bushing with pressurized oiling ensures optimal performance, with oil passing from the lifters through the pushrod and adjusting screw, reaching the rocker arm bushing. This fully bushed design eliminates needle bearings, resulting in higher load capacity, lower friction, better oil control, and improved spring stability.
Increased pushrod and roller interface for higher abuse handling and increased RPM capability.
3/8 ball adjusting screws for better performance and oil retention, preventing galling upon startup.
Larger roller wheel (.571”) and pin (.275”) for handling higher engine speeds and cylinder pressure.
This system is designed to handle applications exceeding 24,000 psi cylinder pressure and engine speeds over 12,000 RPM, providing unparalleled durability and performance for your racing needs. Upgrade your engine with the Manton Steel Big Block Chevrolet Rocker Arm System and experience the ultimate in racing performance and reliability.
