Manton Racing Products engineers the “I-Beam Rocker Arm” to deliver superior strength, stiffness, stability, and reliability for demanding applications. Inspired by the historical I-beam rocker arm design, dating back to the original Chrysler early Hemi and other designs from as early as 1918, this configuration is renowned for its robust strength and stiffness.

Key Features:

• High Strength-to-Weight Ratio: Crafted from the highest-grade Billet steel, each rocker arm undergoes heat treatment to enhance durability.
• Nitride Tool Steel Shaft: Minimizes the risk of shaft breakage, providing enhanced longevity.
• High-Load Bushing with Pressurized Oiling: Ensures optimal oil flow, reducing friction, and improving spring stability. The fully bushed design eliminates needle bearings, offering higher load capacity, better oil control, and reduced valve train noise.
• Shim Washers for Precise Alignment: Allows for roller-to-valve alignment adjustments and oil spillage control, tailoring oil pressure and velocity to your engine’s needs.
• Enhanced Pushrod and Roller Interface: Features a larger roller wheel (.571″) and a robust .275″ pin, designed to handle high engine speeds and increased cylinder pressure.
• 3/8 Ball Adjusting Screws: Adopted from Top Fuel and Blown Alcohol rocker arm assemblies, these screws provide better performance and prevent galling upon startup.

The Manton billet rocker arms are direct replacements for T&D or Crower rocker arms of the same ratio and can be easily installed on their stands. Perfect for high-abuse applications, these rocker arms offer unparalleled performance and reliability.
