What is the main advantage of a shaft rocker system over individual rocker arms?

A shaft rocker system secures all eight rocker arms onto a single shaft, creating a much more rigid and stable valve train. This reduces deflection and improves overall durability, especially under high engine loads and RPMs.

Does this rocker kit require any modifications to my engine?

No, this COMP Cams Max-Lift BSR Shaft Rocker System is designed as a bolt-in upgrade. It requires no machine work and is engineered to clear factory valve covers on compatible LS engines.

What is the benefit of the plasma nitriding on the rocker shafts?

Plasma nitriding is a surface hardening process that significantly increases the durability and wear resistance of the rocker shafts. This makes the system more robust and capable of handling aggressive valve train setups and high mileage.

Product Details

If you're looking to get the most out of your GM LS engine, especially when pushing it hard, upgrading your valve train is a smart move. This COMP Cams Max-Lift BSR Shaft Rocker System is designed to significantly improve the stability and durability of your valve train, reducing deflection and ensuring more precise operation under high loads. It's a bolt-in upgrade that works with popular LS1, LS3, and LS7 cylinder heads, fitting a wide range of vehicles including the Chevrolet Camaro, Cadillac CTS, and GMC Sierra.

What sets this system apart is its unique bushed shaft design. Instead of individual rocker arms, all eight are secured onto a single shaft, creating a much more rigid setup. This rigidity is further enhanced by thin, tri-layer rocker arm bushings that help reduce deflection and avoid the high stress points found in needle bearing rockers. This increased stiffness means your LS engine will be more efficient and durable, even when you're asking a lot from it. COMP Cams also built in provisions for extra oiling through the rocker shafts and plasma nitrided the shafts themselves, adding even more durability, making it a solid choice even for aggressive solid roller valve trains.

This kit is engineered for a precise fit and requires no machine work, clearing factory valve covers. It's a comprehensive solution for anyone serious about valve train performance and longevity in their GM LS engine.
