Description
COMP Cams is proud to announce another industry first: a bolt-in-ready Bushed Shaft Rocker System for GM LS engines. Thanks to innovative engineering, this patent pending Bushed Shaft Rocker System increases valve train stability and durability while decreasing deflection and providing bolt-in convenience for LS1, LS3 and LS7 cylinder heads. The COMP Cams Bushed Shaft Rocker System improves valve train stability and durability by securing all eight rocker arms onto a single rocker shaft. Thin tri-layer rocker arm bushings reduce rocker arm deflection and eliminate the high Hertz loading that can occur in needle bearing equipped rockers. Reduced rocker deflection increases valve train stiffness, ensuring that your LS is more efficient and durable under high loads. COMP Cams engineers worked to ensure long-term valve train durability by perfecting rocker to valve stem geometry and provisioning for supplementary pressurized oiling via threaded ends on the rocker shafts. Additionally, each rocker shaft is Plasma Nitrided, further increasing the system’s durability even when used with aggressive solid roller valve trains. The COMP Cams Bushed Shaft Rocker System for GM LS delivers high-level valve train stability, precise fitment, truer valve train geometry and increased load-bearing capacity in a package that is ready to bolt in that requires no machine work.
