GY6 Valve Keeper Set 4-Piece 125cc 150cc

GY6 Valve Keepers for 125cc to 150cc Engines

These GY6 valve keepers hold the spring retainer onto the valve stem, which helps stop valves from dropping out when the engine runs at high RPM. The set contains four precision-hardened valve cotters that work with both intake and outlet valves in standard 2-valve GY6 cylinder heads. They are one of the key GY6 scooter parts for keeping your engine running well and dependable.

Precision Engineering

These keepers are made from high-tensile alloy steel, so they can handle wear and hold their shape under constant spring load. The precise taper fit creates a secure mechanical lock between the valve stem and the spring retainer, an important factor in how the engine works.

Complete Service Solution

The set has four pieces, made up of two pairs, so you have what you need to service both the intake and outlet valves in a 2-valve GY6 cylinder head. They work as a dependable substitute for original components across a range of GY6 engine models.
