Overview
The COMP CAMS GM LS LSR Hydraulic Roller Cam LS279HV12 is engineered for fifth- and sixth-generation LS engine builds—including 5.3L, 6.0L, and 6.2L variants—to deliver aggressive performance without sacrificing street usability or daily drivability. Its hydraulic roller design minimizes valve float at high RPM while reducing friction and wear compared to traditional flat-tappet setups. Optimized valve events enhance cylinder scavenging and fill in naturally aspirated applications without requiring costly electronic tuning or fuel system upgrades.
