Ford Shelby GT500 Camshaft Set - COMP Cams - Stage 1 Thumpr No Springs Required. This drop-in camshaft set delivers the signature Thumpr idle with proven street manners, without requiring a valve spring change.

Engineered for the 2018+ Ford 5.0L Coyote’s direct-injection cylinder heads, these new COMP profiles draw on GT350 race-engine data and are matched to the updated port and chamber geometry. The Stage 1 NSR Thumpr leverages the cam-driven DI pump to help support fuel flow potential, while offering stronger power throughout the rev range and improved high-RPM stability compared to factory cams—ideal for mildly modified builds seeking sound, response, and reliability without complicating installation.

• Optimized for 2018+ Coyote direct-injection heads
• Profiles informed by GT350 race-engine data
