Product Description

This valve collets and valve spring seat set is high-quality aftermarket engine spare parts specially designed for SQ150 150cc motorcycle. The valve collets (also known as valve keepers or cotters) lock the valve stem firmly in place. The valve spring seat acts as a base to hold the valve spring. These two components work together to stabilize the valve assembly and maintain precise valve timing while the engine runs.

Manufactured from hardened alloy steel with heat quenching treatment. It can withstand the high temperature, pressure and frequent impact inside cylinder head at high RPM, resisting cracking, deformation and fatigue failure. Precision CNC machining guarantees consistent dimension and tight fit on valve stem and valve spring.

Perfect replacement kit for worn, broken or deformed original valve locks and spring seat during cylinder head overhaul, engine rebuild and regular maintenance. No cutting or modification required for installation.

Key Features:

  • ✅ Exact fit for SQ150 150cc motorcycle engine
  • ✅ Hardened alloy steel with quenching treatment for high temperature working environment
  • ✅ Precision machined for seamless fit with valve stem and spring
  • ✅ Anti-fatigue, wear-resistant for long service life
