COMP Cams Max-Lift BSR Shaft Rocker Kit Chevy LS1

Starting with the thin tri-layer rocker arm bushings, this COMP Cams Bushed Shaft Rocker System is designed to reduce rocker arm deflection and eliminate the high Hertz loading that can occur with needle bearing rockers. This is a bolt-in ready system for GM LS engines, meaning you get increased valve train stability and durability without needing any machine work. It secures all eight rocker arms onto a single rocker shaft, which helps to increase valve train stiffness, making your LS engine more efficient and durable, especially under high loads.

COMP Cams engineers focused on long-term valve train durability by perfecting the geometry between the rocker and the valve stem. They also included provisions for supplementary pressurized oiling through threaded ends on the rocker shafts. Each rocker shaft is Plasma Nitrided, which further boosts the system's durability, making it suitable even for aggressive solid roller valve trains. This system offers high-level valve train stability, precise fitment, truer valve train geometry, and increased load-bearing capacity.

This kit fits a wide range of GM LS engines, including popular models like the Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Tahoe. It clears factory valve covers, simplifying installation. The plasma-nitrided shafts ensure this system can handle demanding use over time.
