Ha.....I get that all the time! I didn't know they were prone to bending though, thanks. I only do trail riding so hopefully that wont be an issue.
Only thing I don't like is that the skid plate rubs the chain with this swinger and it didn't with the stock swing arm. When they were purchased pro armor said it would work.
I bought everything off a friend that was parting out his 04, everything was brand new never opened, but they have them on Houser's website.

I also have the SS front brake lines and clamps, just haven't gotten around to putting them on yet.
