Built to ARP's proprietary standards, the tool removes rust, dirt, and minor deformities to help fasteners seat properly again. It’s not vehicle- or application-specific—use it wherever M8 x 1.25 internal threads need refreshing.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the chaser restore thread function without re-cutting?\u003c\/h3\u003e\n\u003cp\u003eThe ARP chaser reshapes and cleans existing thread crests rather than removing substantial material.
