Comp Cams 910-16 Valve Springs for 7.3 Powerstroke

Upgrade your 1994–2003 Ford 7.3L Powerstroke with the Comp Cams 910-16 single valve springs (set of 16). These high-performance springs deliver higher seat pressure than stock to keep valves properly seated under elevated boost and with performance injectors.

Stock 7.3 valve springs typically provide only about 71–79 lbs of seat pressure, which is inadequate once boost climbs past the mid-30s psi or when running Stage 3 injectors (238cc). The 910-16 springs raise seat pressure to approximately 92–94 lbs at the recommended 1.85" installed height, helping prevent valves from being forced open by cylinder pressure and reducing the risk of valve-to-piston contact.

Key Features & Benefits

• Higher seat pressure for better control under boost and with larger injectors
• Single outer spring design with damper for improved stability
• Harmonic-resistant design and quality ovate wire for durability and reduced mass
• Supports higher-horsepower street and competition builds
• Direct upgrade for stock or modified 7.3 Powerstroke engines
