Unmatched Strength and Reliability

Manton engineers the I-Beam Rocker Arm Assembly  to deliver superior strength, stiffness, and stability, making it ideal for high-abuse applications. Drawing on the robust I-beam design, historically from Hemi rockers and other designs dating back to 1918, this configuration is proven to provide exceptional durability.

High-Performance Features

• Superior Materials: Made from the highest-grade billet steel, each rocker arm is heat-treated to enhance properties. The nitride tool steel shaft further reduces the risk of breakage.
• Optimal Design: The I-beam shape offers the best strength-to-weight ratio, ensuring maximum performance.
• Advanced Bushing System: Featuring a high-load bushing with pressurized oiling, our rocker arm minimizes friction, enhances oil control, and improves spring stability. The fully bushed design eliminates needle bearings, reducing valve train noise and increasing durability.
• Adjustability: Shim washers between the stands and rocker arm body allow for precise roller-to-valve alignment, optimizing performance even after head servicing. Adjusting the shims can also control oil spillage, tailoring oil pressure and velocity to your engine’s needs.

Enhanced Performance Capabilities

• Increased Loading Area: By Expanding both the pushrod and roller interfaces handle higher abuse and increased RPMs.
• Durable Adjusting Screws: Utilizing the same 3/8 ball adjusting screws as used in Top Fuel and Blown Alcohol assemblies, this design ensures better oil retention and reduces wear during start-up.
• Heavy-Duty Roller Wheel: The large .571″ roller wheel with a .275″ pin withstands higher engine speeds and cylinder pressure, proven in applications exceeding 24,000 psi and 12,000 RPM.

Easy Replacement

Manton billet rocker arms can be directly used as replacements for T&D or Crower rocker arms of the same ratio, seamlessly bolting onto their stands.

Upgrade your engine’s performance and reliability with the Manton I-Beam Rocker Arm Assembly, designed for the most demanding applications.
