Supertech Performance SEAT-TS-SUH6E Valve Spring Seat Exhaust Side 2.4mm for Subaru H6 EZ30 with TS1015 Spring

The Supertech Performance SEAT-TS-SUH6E is a precision-engineered exhaust-side valve spring seat designed specifically for use with the Supertech SPR-TS1015 valve spring on the Subaru H6 EZ30 engine platform. At 2.4mm thick, this spring seat locator ensures proper spring placement and consistent valve train geometry during high-performance and high-RPM operation.

Valve spring seats function as precision shims between the cylinder head and the base of the valve spring. Proper seating is critical to maintaining consistent spring rate, preventing coil bind issues, and ensuring long-term valve train reliability under demanding conditions.
