Hi Everyone.... this is my first post here so please go easy on me.

Been looking at changing my risers on my America for some 4" High pullbacks.

Couple of questions....

I've been led to believe that thats the max I can go with stock cables etc, can anybody confirm this for me.

Seen lots of reasonably priced ones on Ebay.... any good?

Also seen lots of harley ones for 1" bars, but what about the top yoke/tree bolt size.

Also had a look at the risers they make for the new T Bird when I was in my local dealership but they are rubber mounted and their mechanics could not confirm compatibility.

Hoping someone can give me a few pointers.
