LS Hyd Roller Cam 3-Bolt .553 /.553 116 Degrees

The LS Hydraulic Roller Cam 3-Bolt .553 /.553 116 Degrees from CAM MOTION INC is a purpose-built hydraulic roller camshaft engineered for mild to moderate performance applications in LS-series engines. This camshaft delivers 0.553-inch lift on both intake and exhaust with a 116-degree lobe separation angle (LSA), optimized for the 2500–6000 RPM operating band. The 3-bolt mounting configuration ensures compatibility with standard LS platform engine blocks, making this an accessible upgrade path for builders seeking improved breathing without requiring bottom-end modifications.

The hydraulic roller design eliminates valve train friction and reduces wear compared to flat-tappet systems, translating to improved fuel efficiency and longer component service life. With a 210-degree intake duration and 216-degree exhaust duration, this profile balances low-end responsiveness with mid-range torque delivery—a proven specification for truck platforms prioritizing everyday driveability. The tight 116 LSA promotes steady idle quality and predictable power band characteristics, making this camshaft suitable for vehicles running factory-style fuel management and stock intake manifolds.

LS engine builders, truck enthusiasts, and performance shops select this camshaft specification for street-driven vehicles where reliability and part compatibility matter as much as horsepower gains. Weighing 9.93 lbs and measuring 24.75 inches in length, this camshaft integrates directly into existing LS valve train assemblies without requiring custom pushrods, rocker arms, or head porting. Whether upgrading a 5.3L, 5.7L, 6.0L, or 6.2L LS variant, this mild-performance profile delivers measurable gains in volumetric efficiency while maintaining OEM-level dependability.
