Thickness doesn't always matter, it's how they are formed and heat treated.

Anyone here running the 9602HD coils from Toytec? Wondering if they would be an upgrade from OME 890s
Toytec Rear 3" Lift Heavy Duty Coils (Pair) - 96-02 4Runner
9602HD-P - Toytec Rear 3" Lift Heavy Duty Coils (Pair) - 96-02 4Runner
We designed these rear coils for use with additional load.
Toytec rear lift coil springs offer a great ride quality and increased rear suspension off-road performance.
These coils provide an average lift amount of 3" (with approximately 300 LBS additional weight).
These coils are custom made to our high quality of standards.
Designed as a pair with side specific coils to help eliminate the typical driver side lean that is common with 3rd Gen 4Runners.
Not for use with stock rear shocks.
Extended rear brake lines recommended.
Sold as a pair.
**Recommended for use with additional constant load or lift amounts will be greater

So is the consensus the Dobinsons 675V won't fit with long shocks like Tokicos? That sucks if so. I was hoping they'd just be slightly smaller 210V's
If you search 9602 in the thread's search function (not the forum's search at the top right of the page) you'll find some here and there posting about them

I kind of forgot about this thread. After having some seat time with the 2890 ome springs, I feel like they were a great upgrade for the extra weight over the 2906.
For a close to level, daily driving, some wheeling, without lots of weight (stock skids and such)on a 2” lifted 3rd gen, it’s almost perfect. It’ll hit the bump stops more and more as weight in gear and armor goes on.
The 2890 ome did add a lot of lift though. Definitely has a rake now even with weight. I’m starting to rebuild the front end with all new Toyota lower arms, JBA uppers, and I’m planning to move the 6112 coils up to the 2.3” from 2” to see if that gets it about at the right ride height. It’s really cushy thought for the high speed rally stuff.
The 2890 did reduce the bottom outs greatly. It feels like a lot of travel was added since it’s not constantly hitting the Duro bumps now. A sway bar adjustment was needed though, which helped the added body roll greatly. I have an eimkeith PCK on order to hopefully alleviate the body roll since the added ride height with the 2890. I’m sure the rear end bushings are also shot.

I thought the 906 are heavier than the 890’s? 220 vs 190?
I loved my 890’s when I ran them. They don’t have enough free length and high enough ride height for my setup, and like you said, they get overloaded quickly just because they don’t sit high enough to keep off my extended bumpstops & longer compressed length shocks when you have any real weight in the back. They work best with the 4Runner 5100’s or similar ext/ comp length shock from my experience. That way you do without the bump extension and maximize their bump travel before making contact with the axle.
There’s not much for options between 890’s and LC coils ride height-wise unless you’re mixing trim packers and/ or spacers. I wanted to try the Dobinsons but they seem like their options are just like the older aftermarket offerings (ARB & Toytec primarily). Either too short or too long for my ride height and spring rate preference. That’s why I settled for the older Toytec Superflex even though they’re a 240 lb spring rate and would have preferred 200-220 ideally. They have plenty of free length to prevent dropping a coil when using the longer travel shocks and also sit at a decent ride height to avoid contacting the bumpstops too easily and don’t sit at 4”+ lift unloaded. I had to settle on a heavier coil to get the other properties I needed out of a rear coil.
It’s a game of give and take the way the rear suspension on these vehicles work.

Your right, The rate is higher on the 2906, like you said at 220 pounds per inch. But the free length is much shorter. I plotted out the spring rate, and even though the 890s spring is a lighter 190 rate, the addition of free length comes into play and ups the ride height at a given load much better than the 2906.
Some force examples.
190x3 =570
220x2.59=570
190x4=760
220x3.45=760
I do sometimes wonder if a 220 rear spring rate is probably a better match for the 600 pound front spring rate with my 6112 shocks, slightly at least. But the issue is is getting the right freelength in that spring rate. Even when you go to the 891, you get a shorter spring.
Other reason for my decision to go with the 2890 was the sales guy at Wheelers said a coworker had 2891 springs in his 4runner and it rode like crap since there wasn’t hardly any weight on it. He said you better have some bumpers and a drawer system, otherwise you won’t like it. So I went the 2890 route.
My thinking was the rear springs are cheap enough to replace when/if I cross that bridge.

Do you know how much lift you’ve got with the older Superflex coils? I just picked up a set as well and am hoping for a similar result. Do you know if all older Superflex coils are the same at the 240lb rate?
The reason I started this thread was to basically gather data, start discussion, and chat about the “perfect rear 3rd gen spring”. I still think a coil that rode like an 890 but had a longer free height would be a great rear spring option for our trucks. ~2.5” of rear lift with a small/medium load and the ability to run longer shocks would be so nice, all while keeping suspension geometry closer to factory at its static height. I should look into a GB for getting a custom run of springs made. I wonder who Toytec uses to manufacture their springs…
Anyone know the free length of an 890?

Right at 3” or 23” hub to fender. My Nguyen Works single rear swing out and 35” spare added a little weight overall but not much. I am roughly 60 lbs over stock weight w/ tow hitch. I also have the rubber cone bumps removed, which cuts 1/4” from the static ride height. From what I remember, Toytec only offered the Superflex with 3.75” lift, and their medium/ light duty 3” lift coil with a shorter free hight and the rest of the offerings were made by OME. It’s been a while since that was the case though, so I’m a little fuzzy on it.

I agree completely. There is a bit of a gap between the 4runner offerings, and then jumping all the way up to a landcruiser Spring.

4Runner 901's, cone bump stop, 5" Durabump, plastic spiral wrap on axle end of spring has 3.5"
between Durabump & Axle.
Runner facing house is unloaded 23.5" hub to flair, facing away backseats down has 880# of sacrete centered
with wheel wells slightly rearword. Didn't measure hub to flair, Durabump to axle was 2.5" to cone 4"+-.
Loaded in city traffic merges turns 4 mi no problem with handling. Stopping had to plan.
On the flex ramp S/B a limiting factor, didn't take time to disconnect, LC 5160's had travel left..can't say spring does or doesn't pop out.
So far I'm liking this setup.

My favorite rear combo was the Downey Off-Road 3" linear rate springs with OME 60027 shocks. I also ran the stock upper isolator with the cones removed and an OME 10mm trim packer per side. That combo rode super nice on road, dealt with the loads I subjected it to, including towing, and absorbed off-road bumps nicely. I was super-bummed when Downey shut its doors in 2009.
I'm reasonably happy with the LC 7.5/Black Tokico combo I currently have. But it annoys me that I need to keep weight in the back to have it ride at the height I want and with the ride quality I am looking for as well. If I could figure out a way to cut a wrap off the LC coils, I'd do it.
I've included a picture from 2004 with the aforementioned Downey/OME combo in the rear with SAW's in the front set to ~2" of lift. Stock wheels, 285/75/16 BFG ATs. My wife is mugging for the camera.

Man, the glory days! Reading you talk about Downey Offroad and your photo with the OG BGF K0’s made me take a trip down memory lane.
Looks like a nice setup! And I totally agree - LC 7 wraps are great but you need some weight to sag em so your not rolling around on 4”+ of lift.
The SAW's required a rebuild at one point. I had already replaced the lower Heim joints once. Rather than spend more money on the SAW's, I bought the TRD/5100 setup. Huge improvement in on and off-road ride quality. It also flexed better in the front with the sway bar attached than the SAW setup did without. That's why I stopped disconnecting my end links. For the stuff I run, it's not necessary. I have enough dents in the truck, thank you very much.
Prior to the SAW's and Downey springs, I had NWOR progressive springs front and rear with Bilstein 4600's. The NWOR springs either sagged (front) or rusted out (rear). They also rode pretty terribly in the rear without a load. I ran the Downey's with the 4600's for a while. The OME 60027's were another big improvement in ride quality. Those shocks ride pretty good with linear rate springs and pretty crappy with progressive springs in my experience.

There are several Genuine Toyota coil spring for the front of the LC80. different part numbers for number of wraps. So you'll need to determine the number of wraps so you can determine the part number. There was thread in here that had the part numbers and the corresponding number of wraps.
There are also aftermarket coil springs from OME and Dobinsons, among others.

You want the coils from a 95-98 FZJ80:
48131-6A570 Genuine Toyota Spring, Coil, Front
The color codes on the springs are Double Purple, Light Blue, White. These are the coils on my 4Runner.

I think I've started to find various part numbers, thanks. Currently using Dobinsons but I want less lift, I'm so damn tired of having rake :ranger:
Do you have any weight in the rear? I got a rear bumper so I'm debating between 7.5 and 8 wraps to compensate, thinking I should shoot for the 19.25" or 19.5" 8 wraps instead
I have a hitch, stock bumper, 33" spare, 10" bandpass subwoofer, 100 lbs. of sand bags, tools, pump, etc. I'm sitting at 23.5" in the rear and 22.5" in the front. 1" of rake. The above mentioned weight in the rear dropped it 1/2". Besides the ride height reduction, I added the weight for ride quality as well. I'd say what I have would be equivalent to a rear bumper upgrade.
I have the Tokico Black LC shocks. You can get those from Toyota Parts Deal as well.

Alright, we'll see! Just put in an order. I figure if it sits a hair too low it's nothing trim packers can't fix, or worst case scenario sell them on the classifieds and get the next size up. I'm only carrying maybe 200lbs max altogether, so probably a tad more than you but not anything crazy like the 500+ some users carry
