Ultimate Reliability for Your Ecotec Engine

When pushing your GM 2.2L Ecotec engine to the limit, factory head bolts often fail to maintain the necessary clamping force. The ARP 231-4701 Head Stud Kit is the industry standard for high-performance street and track applications. Manufactured from premium 8740 chromoly steel, these studs are heat-treated to provide superior tensile strength and fatigue resistance compared to OEM hardware.

Key Technical Features

• Material: High-strength 8740 chromoly steel
• Tensile Strength: Rated at 190,000 psi
• Design: Precision-rolled threads for optimal engagement and torque consistency
• Benefits: Prevents head gasket failure and ensures uniform clamping pressure across the cylinder head

Whether you are running a stock setup or a forced induction build, these head studs provide the peace of mind required for high-RPM operation. The kit includes hardened parallel-ground washers and high-quality nuts to ensure accurate torque readings during installation. This kit is specifically designed to fit a wide range of GM platforms, including the Chevrolet Cavalier, Cobalt, and Pontiac Sunfire/G5 models.
