GM Head Stud Kit - 2.2L Ecotec

The GM Head Stud Kit - 2.2L Ecotec is an essential upgrade for automotive enthusiasts and engine builders aiming to enhance the reliability of the General Motors 4-cylinder engine. This kit replaces standard factory head bolts, providing consistent clamping force to maintain a secure seal between the cylinder head and engine block. It is suitable for both standard rebuilds and competitive applications.

Manufactured from premium 8740 chromoly steel, the GM Head Stud Kit features a tensile strength that exceeds typical OEM hardware. Each stud is centerless ground for perfect concentricity and heat-treated before thread rolling and machining, resulting in superior fatigue strength. The undercut design allows for even stretching under load, while the included 12-point nuts facilitate easier installation in tight spaces.

This head stud kit is ideal for those looking to ensure head gasket integrity under increased stress. It is particularly beneficial for engine builders who prioritize durability and reliability in high-performance applications. The black oxide finish provides essential corrosion resistance, ensuring longevity in high-heat environments.
