Supertech Performance SEAT-H1020DB Valve Spring Seat for H1020 Series Dual Springs

The Supertech Performance SEAT-H1020DB is a precision-engineered valve spring seat designed for use with Supertech H1020 series dual valve springs. These valve spring seats function as critical spacers that provide proper seating and alignment for high-performance valve springs in Honda K-series and F-series VTEC engines.

Key Features:

• CNC-machined from high-grade steel alloy for maximum durability
• Provides proper nesting surface for Supertech dual valve springs
• Prevents valve spring failure under coil bind conditions
• Maintains consistent valve spring rate and balance
• Essential component for single-to-dual valve spring conversions
• Compatible with H1020 series dual valve spring systems

Supertech valve spring seats are precision-machined components that serve as washers or shims between the cylinder head and valve springs. Without proper spring seats, valve springs cannot function effectively under high-RPM conditions, potentially leading to inconsistent valve spring rates and premature failure. This component ensures optimal valve train performance and longevity in modified and high-performance applications.

Note: Sold individually. Complete engine builds typically require 16 pieces (one per valve). When upgrading to dual valve springs, compatible dual valve spring retainers and keepers are also required.
