3/4"

 

I used the 1 inch, but I dont think it really makes a difference. Way I saw it and from what people told me, it may not help any having longer bolts, but it sure wont hurt anything. Just my .02 cents, I dont think it really makes a difference.

 

As long as a few people are using the 1" and sure they aren't bottoming out then go for the 1", always better to have more screw in the bolt. I have 3/4"

 

use the 1" bolts. You want all the thread you can get in the aluminum heads.

 

I used the 1". One of the threads is a bit messed up so I cut the bolt down to a 3/4 inch and it worked fine. The more thread the better.
