I ordered this tool for my specific 2021 road slip, it's for M8 engines, there's 1 other tool I've used, it's similar for dual cam, well you should know how to use this one If a tool is used snugly, you will need to turn the crank with socket and ratchet to align the timing chain timing marks and turn back and forth until the tool is seated between the timing marks. Please don't try to work if you are not familiar with this tool, it's worth it and it works.
