It’s got around 205k. Put bilstein 5100s on it about 7 years ago.

I know you mentioned not being a fan of the 5100's, but I can't recommend the Bilstein 4600's and 99 tall coils highly enough for ride quality on road. I bought my 99' with 4600s and drove it from California to Oregon (about 500 miles) and it drove fantastic on road and great offroad if not a little soft. If your planning on using it as a daily with little offroad I think the 4600's would work great for your rig. Also, I'd strongly recommend replacing the lower control arm bushings with either whiteline poly bushings or new OEM bushings. I recently did this on mine and it made a huge improvement when hitting potholes as it previously would jerk to the side, but now it feels tight and tracks straight even when hitting ruts or potholes on the highway. Just my .02

Replacing the bushings in the rear suspension eliminated the rear sway. I normally go with OEM bushings but lots of guys have gone with poly bushings and no regrets so I did the same and have been very happy.
I believe Whiteline sells a complete kit of poly bushings. Having a vise as well as a press makes the job a nice weekend project.

7-year-old Bilsteins , it's time. I had a 2wd 02 sport, f*ckin thing wouldn't climb a curb, had to put an Eaton tru trac in it. Sold it. Bought the 99 4wd e/locker. I'll never buy any Toyota truck or 4runner in 2wd.
