{"product_id":"spe-6-7-powerstroke-valve-springs","title":"SPE Motorsport Stage-2 Beehive Valve Springs Set of 32 For 2011-2019 Ford 6.7L Powerstroke","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe 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.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSold 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 \u003ca href=\"mailto:sales@spemotorsport.com\" class=\"underline underline
