Description
The exhaust valve stem is an important component of an internal combustion engine. The valve stem is typically made of high-strength material that can withstand the high temperatures and pressures generated by the engine. It is designed to fit tightly in the valve guide, a cylindrical sleeve pressed into the cylinder head.
Features
- Includes two retainer grooves to hold the valve retainer in place
- Withstands wear between the valve stem and the guide
- Features a 45.75° valve seat face, which reduces carbon buildup on the valve and seat and helps improve engine performance
