COMP CAM 54-275-11 HV Cam 226/234 Camshaft Install Rebuild Kit w/ GM 12499225 Lifters | .575″/.570″ | FITS: Chevy 5.3L 4.8L LS LR4 LM7 L33 LMG LC9 LY5 | Great Drivability | MADE IN USA

Description

The Competition Cams 54-275-11 hydraulic roller camshaft is built for LS Gen III/IV engines and delivers a strong, noticeable performance gain without sacrificing everyday drivability. Its .575″ intake / .570″ exhaust lift dramatically increases airflow through the cylinder heads, letting your LS breathe deeper and produce more power. This added airflow results in quicker throttle response, stronger acceleration and a more energetic overall engine feel.

With 226° intake / 234° exhaust duration @ .050″, this cam keeps the valves open long enough to fill the cylinders more efficiently during the power stroke. That means more torque in the mid-range where you actually drive, better pulling power on the highway and smoother, stronger acceleration throughout the RPM band. Whether you’re merging, towing, or doing spirited street driving, the improved airflow and duration create a cleaner, more powerful response.

The cam’s design strikes a perfect balance for street and light strip use. It adds a deeper, more performance-oriented idle tone without making the engine unruly or overly choppy. Once tuned, the engine maintains stable street behavior while producing a satisfying exhaust note that clearly lets people know the engine has been upgraded.

If your LS build includes bolt-ons like an upgraded exhaust, headers, intake or tuning—or if you simply want more power without going extreme—the 54-275-11 is an excellent choice. It elevates the engine’s personality, providing stronger low- and mid-range torque, improved throttle feel, and an overall more exciting driving experience.
