Pml

Hey so I am going to do a PML on a 2003 Nissan Xterra XE-V6 stock has no after market products---I want to know I keep reading that changing the front and rear shock/struts would be best for better ride. Now my question is. What Shock should I be looking at. I was looking at Bilstein B6 4600 Series Shocks and Struts but not sure if there is a better deal out there or something else I should be looking at. Also anything else I should be looking into while considering doing a PML. I am trying to just do like rock crawling for now as this is my only vehicle until I get a different car for commuting.
