Supertech Performance SEAT-EC1015 Valve Spring Seat Locator for Dual Springs SPR-TS1015 / SPR-TS1012

The Supertech Performance SEAT-EC1015 is a precision-machined valve spring seat locator designed to properly position and nest Supertech dual valve springs during installation. Engineered as a matched component for the Supertech SPR-TS1015 and SPR-TS1012 dual valve spring series, this seat locator ensures correct spring alignment and seating geometry for consistent valvetrain performance.

As part of Supertech's comprehensive valvetrain system, the SEAT-EC1015 works in conjunction with Supertech's dual valve spring kits used in applications such as the GM Ecotec LSJ and Mitsubishi 420A engines. Proper spring seating is critical to maintaining accurate seat pressure, open pressure, and coil bind clearance — all factors that directly impact valvetrain reliability at high RPM.
