What is the main benefit of using a shaft rocker system like this?

The main benefit is increased valve train stiffness and reduced deflection. This means more of your camshaft's lift is transferred directly to the valve, making your engine perform as if it had a slightly larger camshaft and allowing for more aggressive cam profiles.

Does this rocker system come with everything needed for installation?

Yes, the COMP Cams Max-Lift BSR Shaft Rocker System ships fully assembled, making it a bolt-on installation. You will want to refer to the manufacturer's installation instructions for any specific details or torque specifications.

What specific GM engines does this rocker system fit?

This system is designed for GM Gen V LT1, LT2, LT4, LT5, and L86 engines. It is explicitly stated that it does NOT fit GM Gen V L83 (5.3L) cylinder heads.

Product Details

If you're working on a GM Gen V LT1, LT2, LT4, LT5, or L86 engine and looking to get the most out of your valvetrain, consider the COMP Cams Max-Lift BSR Shaft Rocker System. This system ties pairs of rocker arms together, which significantly improves how the valvetrain operates. It's designed to increase stiffness and reduce deflection, meaning more of your camshaft's lift actually makes it to the valve instead of being lost to flex in the cylinder head or the stock rocker mounting system. This makes your camshaft act like a slightly bigger one and allows you to safely run more aggressive cams without the valvetrain going out of control.

What sets this system apart is the use of a tri-layer bushing instead of traditional needle bearings. This design choice helps reduce deflection, leading to increased rigidity and less wear on the rocker pad. The parallel contact sweep between the rocker pad and valve tip is maintained, allowing the rocker to safely handle up to .675” of valve lift. This means you can push your engine harder and achieve higher RPMs with more confidence in your valvetrain's stability and durability. The system comes fully assembled, making it a straightforward bolt-on installation for your LT engine.

It's important to note that this system is specifically designed for the GM Gen V LT1/LT2/LT4/LT5/L86 engines and does NOT fit GM Gen V L83 (5.3L) cylinder heads. When you're aiming for improved valve train dynamics, increased strength, and better durability, this shaft rocker system is a well-built option to consider for your build.
