Description
Description
The Competition Cams 54-444-11 XFI XE-R hydraulic roller camshaft is engineered for GM LS Gen III/IV engines (1997–2015) and built for enthusiasts who want serious street or street/strip performance. With .581″ intake / .588″ exhaust valve lift, this cam unlocks dramatically improved airflow — letting your LS inhale more air and exhale exhaust more efficiently than stock. That translates into a stronger, more aggressive engine character and real power gains you can feel when you floor it.
With 224° intake / 230° exhaust duration at .050″, the valves stay open long enough for improved cylinder filling and combustion, giving a broader, more usable powerband. From everyday driving to wide-open throttle, your LS will deliver crisper throttle response, stronger mid-range torque, and a top-end that climbs harder and pulls longer. If your build includes upgraded heads, intake, exhaust or tuning, this cam ties everything together for a meaningful performance boost.
The 114° lobe separation angle (LSA) creates a confident, performance-cam idle — a throaty, authoritative sound that lets bystanders know your ride is built for more than stock behavior — while still allowing for manageable street-drive manners once tuned properly. It’s the kind of aggressive engine tone that turns heads without compromising drivability.
Whether you’re building a weekend cruiser, a muscle-car street car, or a strip-ready street/strip LS, the 54-444-11 gives your engine real presence, stronger power, sharper throttle response and that unmistakable “cammed LS” sound. If you want a significant, visceral upgrade from stock that still plays nice on the street, this camshaft delivers exactly what you’re after.
