Description
Description
The Competition Cams 54-702-11 Stage 2 Thumpr hydraulic roller camshaft is built for GM LS Gen III/IV 4.8L/5.3L/6.0L truck-based V8 engines — the upgrade for anyone who wants serious power with that classic V8 attitude. With .541″ intake / .539″ exhaust lift, this cam opens the valves much wider than stock, letting your LS engine inhale and exhale significantly more air and fuel. That extra airflow immediately improves throttle response, torque and overall engine energy, delivering a stronger, more aggressive feel under load and at the stoplight.
At 226° intake / 237° exhaust duration @ .050″, the valves stay open long enough to maximize cylinder filling and exhaust scavenging, giving you a clean, usable powerband. You’ll get robust mid-range torque, sharper throttle response, and improved drivability whether you’re towing, hauling, or doing everyday driving. The 54-702-11 breathes easier across the RPM range, so the engine pulls smoother and stronger down low and still revs cleanly when you push it.
The cam’s 113° lobe separation angle (LSA) helps deliver that unmistakable “Thumpr” idle and performance tone — a deep, choppy, muscular exhaust note and lope that immediately tells people your build isn’t stock. When installed with proper supporting mods (headers, exhaust, correct tune, maybe converter/gear), this cam gives your LS that signature V8 growl and aggressive character without being so wild that it’s impossible to drive.
Whether you’re building a street-work truck, a tow rig, or a weekend performance ride, the 54-702-11 is a great choice. It gives you increased torque, better throttle feel, stronger mid-range power — and that classic Thumpr sound and attitude that makes driving feel more visceral. For anyone wanting to wake up their LS and give it real V8 personality, this cam makes the difference.
