Description

The ARP 231-4701 is a cylinder head stud kit engineered for GM 2.2L ECOTEC engines, providing a robust solution for engine assembly and performance applications. These studs are crafted from premium 8740 chromemoly steel, known for its exceptional strength and durability, with a protective black oxide finish to resist corrosion. The kit includes specialized 12-point nuts, offering a secure and reliable clamping force. Designed with performance in mind, the ARP 231-4701 features undercut studs which help to reduce stress concentrations and improve overall stud longevity. This attention to detail ensures that the cylinder head remains securely fastened, even under demanding operating conditions. The 1/4" thread size is standard for many GM 2.2L ECOTEC applications. This kit is presented as a "Complete Street Performance" upgrade, suggesting suitability for both daily driving and more spirited use. The use of head studs instead of head bolts offers advantages such as superior clamping force and the ability to be reused in many applications.
