Supertech SEAT-H1020DS – Spring Seat Locator for Dual Valve Springs (Single Piece). A precision-engineered, hardened-steel spring seat locator designed to ensure proper seating, alignment, and consistent performance of dual-valve springs (H1020 series) in Honda and Acura engines like the K-Series, F20C, F23, and certain H-Series applications. Essential for maintaining spring stability and safeguarding against valve train wear.

Features:

Hardened Steel Construction: CNC-machined from robust steel alloy, this seat locator is built to endure the high stresses of valvetrain operation—providing strength and longevity.
Precise Spring Positioning: Prevents valve springs from shifting during operation, which helps maintain balanced spring rates, reduces the risk of coil bind, and supports consistent engine performance.
Designed for dual-spring H1020 configurations commonly found in: Acura RSX (e.g., Type-S), Honda S2000, Acura TSX, Acura ILX, Honda Civic Si, Other K20A2/K24A2/F20C/F23 engine applications
Single-Piece Convenience: Available individually, making it suitable for replacing just one seat or completing partial builds. For full installations, it’s available in a set of 16 (SEAT-H1020DS-16).

The Supertech SEAT-H1020DS is the go-to spring seat locator for dual-valve spring setups in performance Honda and Acura engines. Its strong construction, precision engineering, and affordable pricing make it a reliable upgrade for anyone looking to maintain or enhance valvetrain integrity—whether for a single cylinder or a full-head build.
