How has nobody said this yet...
Just get new stock suspension. The stock suspension is very comfortable, and cheaper than OME or any other lift shocks. Unless you definitely want a lift, or need ro carry extra weight, just go with stock replacment. Sonoran Steel has a stock set for the 99, which was the tallest year (1 inch taller than the 2000's).
Too bad you can't demo shocks like you can snow skis. I just want a good ride. Who doesn't? Following is a chronology (simpler for me and easier to read):
My Rig: 1999 4Runner LTD, supercharged, currently ~ 225K miles, second engine & drive train @ 203K, tall coils all around, original suspension, no lift, great rig, my second 4Runner, 3rd counting a totaled unit I inherited.
7/2011 installed a new set of Bilstein 4600's; tires were Dunlop AT's, ride seemed great
8/2013 hauled a heavy load, & boat, may have trashed the Bilsteins but didn't notice until later?
1/2014 motor/tranny swap
9/2014 new tires, Michelin XLT2's, ride wasn't the same as with the Dunlop's
I'm not sure I was ever that happy with the Bilstein 4600 series. They sat on my garage shelf new and in the box for 3 years before installation. Would they go bad on the shelf? (They were to be used on 2000 4Runner which was totaled in '09.) I think I began to notice a difference when I installed the Michelin's. Bilstein's are mush now.
==>> :gun6: Here's my question if anyone cares to respond:
[Anyway I think it's all a personal decision other than I'm wondering if the taller coils work best with certain shocks?]
Maybe I'll just have to go stock again or try the Bilstein 5100HD's. As a footnote, I did have Monroe's on installed by Les Schwab back in 2006 I think it was but they broke and I installed the Bilstein's myself.
