I won't be crawling or doing crazy off-roading, this will be a daily driver and camper/trail boy. I purchased a 2007 v6 4wd runner with 150k on it.
Again, welcome, and again, thx for your patience. Your response told me all I need to know about you as a person, and it's appreciated.
I bolded the things I can address from experience. I too have a 2007 V6 and my off-roading needs are similar so I hope what I can share will be especially useful as you decide what works best for you.
For daily driving and a bit of minimal pedestrian off-roading I have come to conclusion that Bilstein 5100's and OME 884's on all 4 corners would make sense for me. I'll be purchasing FN five star wheels that are 16x8 I do believe? And you all have convinced me that BFG KO2's will be wrapped around them. I don't want a crazy lift so I was thinking setting the rates at 1.75'. will that be a level lift without raising the back or will I need to raise the rears? Also if I run 265/70/r16 tires will I need wheel spacers? And are UCA upgrades a requirement/suggested/option?
[MENTION=280013]andreylights[/MENTION] gave some good advice. If you're after functionality, a stock 4R is very capable off the pavement and anything you do to improve it will just make it better. My truck has an upgraded suspension but is still stock in the sense that my components came off a 2015 TRD Offroad Tacoma (full details in the "X-REAS delete..." post linked in my sig).
It may be useful to take 10 minutes to watch my YT vids (channel is linked in my sig) on the 2018 and 2019 Kentucky Toyota Trail Rides. I ran the first one on my 11-year-old X-REAS and stock springs and the latter one on my new setup. Truck handled and rode
much better in '19 but my point is it had no trouble negotiating some nice and reasonably challenging terrain either way.
Suspension is a tough choice b/c you can spend as much or as little as you want, opinions are so subjective, and most of all, it's not a shirt you can return if you don't like the fit. I imagine there are people who drop $1,500 on something, drive a couple of miles, and go, "Aw crap..." because you can't know how you will like the setup on your rig until you drive it. That's why I went cheap the first go round. Now that I know I love the setup, I'll ride my 4600s till they're done and replace them with a new set of Bilsteins.
If possible, you could also check out 4R groups close to you and see if anyone has the same components you're considering and see if they'll let you ride shotgun. Even a trip around the block will leave you with that much more information before you dole out any $.
About spacers, I run Spidertrax and believe the stance is how Toyota should have made 4th Gens look to begin with (see my build thread for more). With that said, I run the stock tire size now so I can't comment on whether you'll need them to get the look you want. Be aware that it is critically important to install the spacer lugs correctly, which is with the beveled side in and flat side out, using red thread locker, and properly torqued.
I'm also debating between a pioneer AVH-2550NEX and Kenwood DMX7706S head unit? Didn't know if anyone had opinions on those.
I
definitely have an opinion. ;-) I bought a Kenwood (but not that model) a few years ago and regretted it. I now have that exact Pioneer HU and it's golden. More on the install in the stereo post linked in my thread. Happy to discuss details on why I like the Pioneer so much better if that would be helpful, just PM me or post in my build thread.
