GM LS FSL Hyd Roller Cam 210/218

The GM LS FSL Hyd Roller Cam 210/218 by COMP CAMS is a precision-engineered hydraulic roller camshaft designed specifically for General Motors LS-series engines. This cam is purpose-built for enthusiasts and professional mechanics looking to unlock measurable performance gains without sacrificing streetability or reliability. The 210/218 designation refers to duration at 0.050 inches valve lift, positioning this cam in the mild-to-moderate performance range ideal for bolt-on modifications, daily-driven builds, and entry-level competition platforms.

Constructed with COMP CAMS' FSL (Full Roller) design and hydraulic roller lifters, this camshaft minimizes friction while maximizing valve events across the RPM band. The hydraulic roller design self-adjusts for lash, eliminating manual valve adjustments and reducing maintenance complexity. The 210-degree intake and 218-degree exhaust duration split promotes efficient exhaust scavenging while preserving idle quality and drivability—critical attributes for street applications where reliability matters. The roller design also extends component life by reducing wear on lifters and pushrods compared to traditional flat-tappet cams, making it a smart investment for long-term durability in high-mileage builds.

This cam excels in LS1, LS2, LS3, and compatible LS-based platforms where stock or mildly modified induction and exhaust systems are retained. It pairs seamlessly with OEM valve springs and pushrods, reducing installation costs and complexity. Mechanics and engine builders commonly specify the GM LS FSL Hyd Roller Cam 210/218 for naturally aspirated performance packages, truck builds seeking torque enhancement, and street cruiser applications where responsiveness and reliability coexist. Proper installation requires cam timing verification and basic machine work; experienced technicians should handle installation to ensure optimal valve overlap and cam centerline positioning for maximum benefit.
