Refresh your valvetrain with the Blue Line GY6 Valve Keeper Set. These precision-hardened valve cotters (also known as keepers or collets) lock the valve spring retainer to the valve stem — a critical component that prevents valve drops and catastrophic engine failure during high-RPM operation. This 4-piece set fully services both intake and exhaust valves on a standard 2-valve GY6 cylinder head.
Key Features
- Precision Hardened Steel: High-tensile alloy steel resists wear and prevents mushrooming under constant spring pressure
- Exact Taper Fit: Factory-correct taper angle ensures a perfect mechanical lock between valve stem and spring retainer
- Complete Set: 4 keepers (2 pairs) — enough to fully service both intake and exhaust valves on a 2-valve GY6 head
