Product Description

The ARP 241-4501 Pro-Series Head Stud Kit is engineered specifically for the Chrysler 2.2 L 4-cylinder engine, featuring M11 hex undercut studs designed for superior clamping performance. Manufactured from 8740 chromoly and cold-forged, heat-treated, then thread-rolled per ARP Pro standards, these studs offer exceptional tensile strength and fatigue resistance. The black oxide finish adds protection while maintaining clean appearance.

Dual socket compatibility (5/8" hex and 3/16" Allen) adds flexibility during installation, and hardened washers ensure uniform load distribution under high thermal stress. This kit replaces the factory hardware for greater durability during high-performance or high-load applications. Fitment is confirmed; compatibility with later model years has not been verified yet. Nuts are not included and must be provided separately.
