Supertech Performance SEAT-DUR1 Valve Spring Seat Locator (Sold Each)

The Supertech Performance SEAT-DUR1 is a precision valve spring seat locator engineered to work in conjunction with Supertech valve springs and retainers as part of a complete high-performance valvetrain system. Designed for Ford Duratec and Mazda MZR engine applications, this spring seat locator provides a critical seating surface that ensures proper valve spring positioning, alignment, and load distribution for consistent, reliable performance under demanding conditions.

Spring seat locators play an essential role in any performance valvetrain build — they center the valve spring on the cylinder head, prevent spring migration, and help maintain precise seat pressure and coil bind measurements. The SEAT-DUR1 is a direct companion component to Supertech's SPR-TS1015 and SPR-TS/DUR-DS valve springs and is commonly included in Supertech's complete spring and retainer kits such as the SPRK-TS-DUR-D1.
