Supertech Performance SEAT-TS-MA18I Valve Spring Seat

The Supertech Performance SEAT-TS-MA18I is a precision-engineered valve spring seat designed to work in conjunction with Supertech valve springs. Spring seats provide a stable, consistent seating surface between the cylinder head and the base of the valve spring, helping to maintain proper spring alignment, reduce wear, and ensure accurate installed height.

Manufactured to the same exacting tolerances as all Supertech valvetrain components, these spring seats are an ideal complement to any Supertech valve spring upgrade or OEM replacement application. Using matched Supertech spring seats alongside Supertech valve springs ensures consistent geometry and maximum component longevity.

Key Features:

• Precision-machined to tight tolerances for consistent installed height
• Designed to pair with Supertech valve springs for optimal performance
• Provides a stable nesting surface to minimize spring walk and wear
• High-quality materials suited for both street and performance applications
• Sold individually — order the quantity equal to the number of valves in your application

Sold Per Piece. For example, a 4-cylinder 16-valve engine requires 16 spring seats — order a quantity of 16 accordingly.
