Do I need extended rear brake lines?

2016 DCLB: I'm running adjustable king 2.5 shocks with the OME Heavy Duty Leaf pack.

I also have the Archive Garage hammer hangers (+0.5") and I will be adding the OME add-a-leaf (+0.5"). Basically my rear is super heavy and even with the HD leaf pack and the hammer hangers not getting much lift hence why I'm going to put in the add-a-leaf.

I'm wondering if I need to get extended brake lines in the rear now or will the shock itself limit this and hence not be an issue unless I went long-travel?

Appreciate the help!

 

I would add them. They're inexpensive and an easy installation.
