COMP Cams Shaft Rocker BBC BDX B-BRo/Drt Ir

Starting with a 2024 aluminum rocker body paired with an 8620 hardened steel shaft, this COMP Cams shaft-mount rocker system is built for serious performance. Unlike stud-mounted rockers, this setup uses a horizontal shaft as the fulcrum. This design significantly increases mounting stiffness, which translates directly to improved valve train stability. When your valve train is more stable, especially at higher RPMs, you get a more efficient transfer of power from the camshaft to the valve, ultimately freeing up horsepower.

This kit is specifically designed for BBC (Big Block Chevrolet) engines using Brodix Big Duke or Dart Iron Eagle cylinder heads, featuring a 1.7 rocker ratio. The engineers at COMP Cams utilized the latest computer technology and extensive field testing across various racing disciplines to refine this design. The rigidity added by the shaft system not only benefits the valve train but also contributes to the overall stability of the cylinder head itself. This is a well-built component aimed at maximizing the power potential of your engine.

When you're looking to extract every bit of performance from your BBC engine, especially when paired with Brodix or Dart heads, a robust shaft-mount rocker system like this one is a critical piece. It’s a direct upgrade that addresses potential flex and instability in the valvetrain, ensuring your camshaft's efforts are fully realized at the valves.
