The Chrysler Secondary Camshaft Chain Holder 522902, is a must when installing the Secondary Timing Chain Kit. Some guys alleged you can install the timing chains without this tool. This may be true if your auto tech skills are “A” Level, by using rubber bands. I suggest buying the tool, one mistake can cause you $$$$$.
