Supertech Performance SEAT-TS-SUB4 Valve Spring Seat Locator

The Supertech Performance SEAT-TS-SUB4 is a precision-machined valve spring seat locator engineered to pair with the Supertech SPR-TS1015-SUB4 dual valve spring. Designed as a critical interface component, the spring seat locator provides a stable, accurately positioned nesting surface for the valve spring, ensuring consistent spring geometry and proper load distribution throughout the valve train.

At 2.85mm thick, this seat locator is manufactured to exacting tolerances to complement the full Supertech valvetrain system. It is sold individually (per seat) — order the quantity that matches your engine's cylinder count and valvetrain configuration. A typical 4-cylinder engine with dual springs requires 16 seat locators (one per valve).

• Designed for use with Supertech SPR-TS1015-SUB4 dual valve springs
