The ride for me unloaded isn't back breaking, you won't need to see a chiropractor even after riding in the back for some time. But it isn't as soft as the OEM ride, probably due in large to the sagging springs.
best rear coils for towing ?

Y'all are making me want to swap my Superflex springs out for some of these 906 units. It's nice they list the spring rate for the 906, and I like that they're progressive. I wish ToyTec would list the rate of their 3" spring.
Thanks for the help and pics .I also read until my eyes bled and this week went with 906/880 setup. My reasoning after speaking with ARB tech was the 906 are made to hold a constant 350lb load without depressing. Both 906 and 890 give same 2'' lift. Tech insisted all I needed was the 890's and that 906's would be stiffer. He also said I needed to buy their shocks/struts and Billy's would over extend ( not true).
I tow a fair amount both boat and enclosed trailer so I couldn't bear the idea of any sag when towing and took my chances. Paired with 4600/hd bilsteins I couldn't be happier. ride is fine, it's a truck. If I decide I need more lift in the back I'll install 5100's but after towing a trailer today I'm completely satisfied and made the right decision. Either will work -906's are fine and also necessary if you regularly carry items or have a steel bumper. Before and after below hope this helps.

Would a trim packer or 2 be worth using to get a little more lift ? would like to switch to 265-75-16 and don't want any rubbing.

you don't need the trim packers since 2" of lift is more than enough for 265/75R16 tires

I am no expert on rear coils, but here is what I'm going to do, and why: I am getting AC Delco replacement coils for a 2007 FJ Cruiser. FJ coils supposedly lift 4Runners a little bit (1-2") and the AC Delco rears are progressive and advertised to support an additional 500lbs of cargo weight. Plus, at $129 for the pair, they are more affordable than OME springs. It's certainly worth the effort to test them, so I'm gonna do that.
Anybody else care to comment on this. seems to be a great option.

I'm running 906's with Rancho 9000XL adjustable shocks. I tow a 4200LBS 17' sportboat. My 4Runner is and has been my primary tow vehicle for 5 yrs. As mentioned, the 906 is a progressive spring and its great, in that the spring articulates nicely, and when you load it, it firms up. Since I installed my 906's, I have no sag when I'm hitched up. With my old stock springs and shocks, it would sag bad, and over rough roads, it would bounce so much it was scary, verging on dangerous. I was considering air bags but the springs were sagging even without a load, and with all the info on this forum, it was obvious a rear suspension upgrade was the only option. After the upgrade, I saw no reason at all to add air bags.
By the way, upgrading the rear took me 1.5hrs with a beer break. Some have trouble with the upper nut, but I didnt.
Later, I upgraded my front springs and shocks with 880's. This made a huge improvement in the overall ride. Considering stock height, I'm 1" higher in the front and 1.5" in the rear, resulting in a 1/2" rake--- perfect.
I'm running Rancho 9000XL's all around, they're adjustable shocks, however, I haven't really noticed a huge difference between the soft/hard setting and for the cost, I might have gone for the 5100 Billies.

Anything else is a compromise. The fact that air bags are so affordable make this an easy decision... in my opinion.

I ran 5th gen springs which are pretty similar to the FJ springs. They are short, will give you a comfy ride on the road. Off-road they didn't do so well, and because they are short there is the risk of popping a spring out. I say air bag it for towing.
Don't waste your money on NEW AC Delco springs for a Toyota. That's a mistake. There is a ton of people that have tried aftermarket springs like moods ect, and have regretted the purchase.

I also have the OME 906 with Rancho 9000XL shocks. For me, it's a great setup for towing my boat. Even with the boat and the rear stuffed with food, drinks, and toys for the lake, it sits perfectly level.
Unloaded it rides great, and looks good too with the very slight rake that it has. Unlike a previous poster, I do notice the difference when I go all the way soft or all the way firm on the 9000 XL adjustable shocks.
906 gets my vote for sure.
EDIT: Also, I still have my airbags installed, but I don't use them anymore now that the OME 906's are on.

I been reading about coil upgrades for a while now and wanted to see what you guys recommend for my situation.
I have a pellet stove and have to haul a ton of a pellets two or three times a year. I used to use my lifted Cherokee and it hauled 1000 lbs no problem but the 4runner rides on the bumpstops with just 800 lbs back there. It's a 99 with the taller coils and they are still at factory height unloaded. I have Bilstein HD's which seem soft or it's the coils that are making them feel soft. There's alot of leaning when taking turns too.
I recently had a couple hundred lbs of tools in the back and it was sagging pretty good.
The most I'd lift this rig is 1" or so cuz it's my daily driver and do not want a tall vehicle. I get 300 miles per tank and would like to keep it that way.
What kind of spring setup would you guys use for my needs? I would like to keep the Bilstein 4600's.

OME 906
I also had the '99 tall coils that were tired and worn out. The 906 was the perfect choice as it eliminated the rear sag and handles loads well.

How much lift did you net?
Got any unloaded pix? Did you keep the front coils or upgrade them as well?

Hard to say how much lift I netted because I never measured and it sagged in the first place.
I think my signature picture is with 906's installed, and with the boat hooked up there is no sag. There's a very slight rake when unloaded and it looks good.
I have not messed with the front suspension at all. I probably should since it's stock and probably needs a refresh.

Ok I will go with those coils and should be able to haul my general tools, recovery equipment, etc without sag.
Appreciate the input!
