GM LS LSR Cam - 269LRRHR13

The GM LS LSR Cam - 269LRRHR13 from COMP CAMS is a precision-engineered hydraulic roller camshaft designed for LS-family engine builds that demand aggressive valve lift and duration characteristics. This camshaft is built for serious enthusiasts and street/strip applications, delivering the timing events required to maximize horsepower and torque across a wider RPM band than stock profiles.

Utilizing modern lobe geometry and COMP CAMS' proven manufacturing tolerances, this hydraulic roller camshaft minimizes valve float while delivering consistent lift across the entire RPM spectrum. The design eliminates the wear patterns associated with solid lifter cams, reducing valvetrain maintenance and allowing the use of standard LS cylinder heads without modification. The cam features a duration of 269 degrees at 0.050" lift, optimizing scavenging efficiency and cylinder filling.

Ideal for LS1, LS2, LS3, LS7, and truck-based LS platform engines undergoing performance upgrades, this camshaft integrates seamlessly into existing LS engine block assemblies without weight distribution concerns. Installation requires proper pushrod selection to ensure optimal performance. Whether building a carbureted LS, EFI conversion, or turbo platform, the 269LRRHR13 specification addresses the needs of builders seeking increased airflow without sacrificing streetable manners.
