I’m new to TW200’s, but just researched this. It seems that a lot end up with the tusk d-flex, they should be around $50. Many liked the bark busters too.
My d-flex arrived yesterday so I have not tried to install them yet, but it appears pretty straight forward watching the various online videos. Just look at what you are ordering, for some reason they named all of their product line d-flex. Some are just plastic guards to keep mud off, some have the full support aluminum bar.
