Product Description

The ARP 244-4300 Pro Series Head Stud Kit is a high-strength upgrade designed for Chrysler Gen-3 Hemi engines, specifically the 5.7L and 6.1L variants. This full kit includes 30 precision-manufactured studs, hardened nuts, washers, and assembly lube. Each stud is cold-forged, heat-treated, and thread-rolled to deliver outstanding fatigue resistance and clamping performance, while stamped to ensure gasket integrity under extreme operating conditions.

With comprehensive socket compatibility - including 14 mm and 10 mm 12-point plus Allen options - the kit facilitates versatile and accurate installation. While ARP confirms the 5.7L/6.1L Hemi fitment, extensive retailer sources also cite support for 6.2L Hellcat, 6.4L 392, Demon, and Trackhawk engines. This stud kit is an essential reinforcement for high-performance builds employing forced induction or sustained high-load, ensuring a robust head-to-block connection. Compatibility beyond model year 2023 remains unverified at this time.
