I'm going to change out my stock risers for some a little taller. I've seen a few different ones with different bolt sizes. My idea is to use the stock hardware and bushings if possible. What size do I need?

 

I'm not sure without checking the bolt head size. If the Head size is 3/4" the bolt should be 1/2". I had added a set of risers from my brother's Lowrider to my "04 FXD.

 

Harley risers are threaded 1/2-13. Some aftermarket ones are 1/2-20.

 

Don't forget, if ya go too tall, you might need longer cables, etc...

 

Oh yeah, I'm planning on changing them. So if I go with risers with the 1/2 - 20 bolts, I'll get new bolts, no sweat. Thanks for the responses.
