I have not done anything with my truck, just preventative maintenance and maintenance items on it. I originally was going to use it for some weekend off road adventures, but I ended up modifying my 2011 Pathfinder instead since I have 3 small kids also. I have done a full front suspension refresh with all Mevotech arms, Bilstein 4600 shocks, and new Timken inner & outer wheel bearings in the last three years. I'll be swapping out the KYB rear shocks for a pair of Bilstein 4600 shocks later this year also. I was thinking about installing Sway-A-Way torsion bars with a pair of 4x4parts UCAs, but probably won't happen anytime soon.
