Description

The COMP Cams Rocker Arm Shaft Stud Kit (Part Number 4589-KIT) is engineered to enhance the performance and durability of your Dodge Gen III HEMI engine. This high-quality assembly features grade 12.9 hardware, providing superior strength and resistance to thread fatigue, especially in demanding race applications.
