Wet Bolts

[Bnrc73]

I need to upgrade my suspension with new shackles and Wetbolts. Looking on line they seem to come in either a 1.125, or a 2.25. What do I measure to know which ones to order. And I know your thinking it so no I am not diy. The shop I’m using doesn’t carry the parts on hand.
Thanks in advance.
