They are VERY easy to install. But as "grandpricks98" stated getting them out is another story. The first set I actually removed in one piece because I wanted to be able to re use them just incase I was not happy with them. When It came time to install the 2nd set in our other car, Well out came the saw and knife.

This made it much easier, but still took some time.
It is well worth the effort... Have fun...
