• Set of 32 covers all intake and exhaust valve stems on the Coyote's 32-valve (4 per cylinder) cylinder heads - complete head coverage in one kit
• Integrated spring seat design replaces both the OEM valve stem seal and spring seat with a single unit - verify spring seat compatibility if running non-OEM valve springs before installing
• CNC-machined to match Ford 5.0L Coyote valve stem diameters - verify compatibility if non-stock valves are installed

Features

• Viton fluoroelastomer construction - resists heat up to 450°F and withstands exposure to fuel, oil, and chemical contaminants better than standard OEM rubber seals
• Integrated spring seat design - merges the valve stem seal and spring seat into one component, eliminating separate seat installation and reducing the chance of misalignment during assembly
• Positive seal lip design - blocks oil from entering the combustion chamber, reducing blue exhaust smoke, oil consumption, and power loss from combustion contamination
• Applied to both intake and exhaust valves - same high-quality Viton compound used throughout, covering all 32 valve stems
• Locks in place securely for reliable operation during extended track sessions or high-mileage street use
• Significantly more affordable than OEM dealer pricing while meeting or exceeding OEM sealing performance in high-performance applications
• Set of 32 provides complete coverage for both Coyote cylinder heads in one kit - no need to source separate intake and exhaust seal sets

Product Description

The GSC Power Division 1101 is a complete set of 32 Viton valve stem seals with integrated spring seats for the Ford 5.0L Coyote V8. Covering all four generations of the Coyote (2011-2024 Mustang GT and 2011-2020 F-150), this kit replaces all 32 intake and exhaust valve seals in a single purchase. The integrated spring seat design is the standout feature - by combining the valve stem seal and spring seat into one component, it simplifies installation and eliminates the risk of misaligning a separate spring seat during assembly.

Made from Viton fluoroelastomer rated to 450°F, these seals offer substantially better thermal and chemical resistance than OEM rubber seals, making them an ideal choice for high-output naturally aspirated builds, supercharged applications, or any Coyote engine that sees sustained high-RPM or high-heat operation. The positive seal lip design prevents oil ingestion into the combustion chamber, reducing oil consumption and maintaining a cleaner combustion environment. Compatible with OEM-diameter valve stems across all Coyote generations; confirm spring seat compatibility if running non-OEM valve spring kits.
