No-limit rear shock mount

[Tree-50]

I'm going to go with this one mainly based on the fact I don't have the crossmember for the stock location fully intact since I'm going step notch route for the future plans. I like the way it mounts to the side of the frame and seems really easy to install.

My question is does it maintain stock length or should I be doing more math? (I guess it's 2 pieces so you could run whatever lenght you wanted huh? But you should still understand my question)

I thought the point of relocator brackets were to run stock shocks and still get max drop/lift from it? I don't want to buy shocks and then realize I am cheating myself an inch or two.


Suspension set up is

front: 2.5" drop spindle, 2.5" boxed lca, stock uca (might pie it if you think it would help go lower from bind. Not sure how to tell)
rear: bag over axle, step notch. Brothers bolt on shock relocator

Thanks in advance.
