ARP M12 Thread Chaser
Premium M12 1.75 Thread Cleaning Chaser
This is the tool you need to properly clean cylinder head bolt threads on 6.2 and 6.5L diesel engine blocks. A must have for anytime you are servicing one of these engines or installing ARP head studs.
A thread cleaning chaser is different from a tap because we don't want to remove any metal during the cleaning process.
