Supertech Performance SEAT-M1015-1 Valve Spring Seat

The Supertech Performance SEAT-M1015-1 is a precision-machined valve spring seat designed to work in conjunction with Supertech valve springs and retainers. Spring seats provide a stable, wear-resistant seating surface between the valve spring and the cylinder head, ensuring consistent spring pressure, proper spring alignment, and long-term valvetrain reliability.

Supertech manufactures these spring seats to exacting tolerances, matching the quality and design standards of their full valvetrain component lineup. The result is optimal load distribution and reduced wear on both the spring and cylinder head surface over high-cycle, high-performance operation.

Key Features:

• Precision-machined for consistent fit and spring alignment
• Engineered to complement Supertech valve springs and valvetrain components
• Provides a hardened seating surface to protect the cylinder head
• Helps maintain correct installed spring height and pressure
• Suitable for performance, racing, and high-mileage rebuild applications

Sold individually (per spring seat). Please order the exact quantity required for your application — for example, a 16-valve engine requiring one seat per valve will need a quantity of 16.
