Product Details

The COMP Cams Max-Lift Bushed Shaft Rocker System represents an industry-first bolt-in solution for GM LS engines, delivering professional-grade valve train stability without requiring machine work. This patent-pending system is engineered specifically for LS1, LS2, LS3, LS6, and LS7 cylinder heads, offering a complete upgrade path for enthusiasts and racers demanding maximum durability and performance.

Key Features:

  • Bolt-in bushed shaft rocker system secures all eight rocker arms onto a single precision shaft for superior stability
  • Tri-layer rocker arm bushings reduce deflection and eliminate high Hertz loading common in needle bearing designs
  • Plasma nitrided rocker shafts provide exceptional wear resistance for aggressive solid roller valve trains
  • Threaded shaft ends provision for supplementary pressurized oiling to ensure adequate lubrication under high loads
  • Optimized rocker-to-valve stem geometry ensures proper valve train motion and longevity
  • Increased valve train stiffness improves engine efficiency and consistency at high RPM
  • No machine work required—true bolt-in installation for LS cylinder heads

By mounting all rocker arms to a common shaft rather than individual studs, this system dramatically reduces valve train deflection and improves load distribution across the entire assembly. The advanced bushing design minimizes friction while maximizing load-bearing capacity, making this rocker system ideal for high-lift camshafts, aggressive spring pressures, and demanding racing applications. Whether you're building a street performance LS or a dedicated competition engine, the COMP Cams Max-Lift Bushed Shaft Rocker System delivers the precision and durability required for consistent high-performance operation.
