The SPE Motorsport 6.7L Powerstroke Stage-2 Valve Springs are heavy-rate beehive springs designed to keep the valvetrain stable and controlled under the extreme cylinder pressures and RPM spikes of a hard-built 6.7L Powerstroke. Snyder Performance Engineering spec'd these Stage-2 springs with heavy-duty rates that maintain full factory retainer compatibility — so you don't need a new retainer set, just the springs themselves.
Sold as a complete set of 32 (enough for a full engine), this is the valve spring upgrade for serious builds running aggressive camshafts, high cylinder pressures, or pushing sustained high-RPM operation. Important: Stage-2 springs require the cylinder head to be machined for proper installation — contact the SPE sales team at sales@spemotorsport.com for full machining specifications before installing.
Features:
- Heavy spring rates control valvetrain at high RPM and pressure
- Beehive design for weight savings vs traditional dual-spring
- Fully compatible with factory retainers, no new retainer needed
- Designed for built, boosted, high-output 6.7L applications
- Critical upgrade for aggressive cam and high-RPM competition builds
