Supertech Performance SEAT-TS-MA18E Valve Spring Seat

The Supertech Performance SEAT-TS-MA18E is a precision-machined valve spring seat designed to work in conjunction with Supertech valve springs and valve seats. Spring seats serve as the interface between the cylinder head and the valve spring, providing a stable, properly located seating surface that ensures consistent spring pressure and prevents premature wear to the head surface.

Engineered to the same exacting standards as the rest of the Supertech valvetrain lineup, these spring seats are manufactured from high-quality materials to withstand the thermal and mechanical demands of high-performance and competition engines. Their precise dimensions ensure correct spring height and load characteristics are maintained throughout the valve train assembly.

Key Features:

• Precision-machined for consistent fitment and spring locating
• Designed to pair with Supertech valve springs and valve seats
• High-quality construction suitable for performance and competition applications
• Maintains correct installed spring height for accurate valve train geometry
• Sold individually — order the quantity equal to the number of valves in your application (e.g., a 16-valve engine requires a quantity of 16)
