Worn or missing valve spring seats allow the hardened steel of the valve spring to grind directly into the soft aluminum of your cylinder head. This GY6 Outer Valve Spring Seat Pair provides the critical thermal and mechanical barrier needed to prevent head erosion and ensure your valve train remains perfectly aligned. If you are rebuilding your top end or replacing valves, these are non-negotiable for a long-lasting engine.
Technical Performance Features:
Hardened Steel Construction: Built to withstand the high-frequency vibration and heat of the valvetrain without deforming.
Direct OEM Fit: Precision-stamped to match the outer diameter of standard 125cc/150cc GY6 valve springs.
Pair Configuration: Includes two (2) outer seats to cover both the intake and exhaust valves.
Surface Ground Finish: Ensures a perfectly flat mating surface to prevent spring "walk" during high-RPM operation.
