Product Details

COMP Cams Mutha' Thumpr NSR (No Springs Required) camshafts are performance camshaft sets for the Ford 5.0L Coyote 4-valve V8. They deliver the distinctive Thumpr idle lope and strong power gains in the mid to upper RPM range. They do this without a valve spring upgrade.

Key Features:

  • No Springs Required (NSR) design: the grind profile works with the factory valve springs, keepers and retainers.
  • One-piece billet steel construction for durability.
  • Hydraulic roller finger follower design for the Coyote DOHC valvetrain.
  • Optimized intake and exhaust lobe profiles for better airflow and exhaust efficiency. The extra exhaust duration produces the lopey, choppy idle.
  • Suited to naturally aspirated and supercharged engines.

Mutha' Thumpr cams are more aggressive than the milder Thumpr grinds. They work best in modified engines with upgrades such as headers, gears or a torque converter. Select the cam set that matches your engine's model-year generation. Some generations require a phaser limiter or lockout kit, while others do not. Check the specific part number's documentation before installing.
