Do they need shims?

 

I asked the same thing about a week ago with no replies so I called Thunder and they told me they like to install them at an inch eight hundred and like to have 130 lbs seat.

 

Isn't 1.800 stock height too?

 

I was worried about the springs tearing up the head.

Thats what I thought.
