Response to the last few posts.
I did some driving around after work today, I can confirm that the ProComp ES9000 is a great shock for a WD21. Smooth and compliant, but still keeps the springs controlled. A great value in my opinion. My rears are a pair of Bilsteins that were from a 2018 Titan Pro4x. Had a pile of new ones that were getting thrown away while I was at the dealership. They were removed from new trucks that got lifted. At the price(free), I and a coworker decided why not give them a try? He put a pair on the back of his lifted 03 Pathfinder and I did the same with my 93. We did have to drill out the bushing eyes to 9/16" to fit over the mounting studs on our trucks and had to grind them a bit thinner, but made them fit. Seems to be working good on the rears of our trucks.
The Firestone Destination MT's are priced in the mid range, my 33x12.50 15's come out to about $250 per tire. They have a 3 ply sidewall, unbelievable grip, very good road manners, long life due to a very thick tread 22/32". They are also lighter than most others out there. Look at tire rack reviews, most people who try them, love them. The ones on the rear of my truck have about 2k miles on them of mostly pavement pounding, put them on last summer. My Pathfinder has a LockRight locker in the rear and at least 300 pounds of "stuff" in the back. Looking at the tires, they still look new with no cuts, chunking, or noticable wear on the tread blocks. I run mine at about 28 psi for the street and light wheeling. Haven't been out doing harder stuff for a long time, but when I was in Moab I kept dropping until I was about 8-10 psi. Never had a flat with any of them either, but only had one flat with my Pathfinder in the 21 years I have owned it, and that one was on my first Moab trip where I managed to snag a sidewall, so I guess I am just lucky concerning punctures with my Pathfinder.
Try them, I honestly believe you will be happy with them.
21 years with my Path, still no broken door handles somehow, knock on wood...
