**Rear Coil Spring Discussion - The Perfect 3rd Gen Rear Spring**

Addison,

I'm late to this discussion. I am very interested in this topic though. I currently am running 861's w/ Tokico LC shocks. I love the flex, but wish the ride height was a little lower. Also, they are too stiff.
For reference, I have a Bandit design rear bumper with dual swing outs (which is heavy) and 35" spare, rear storage / sleeping platform, fridge, Rago rear window panels (full) and usually my 70lb golden retriever. So I'm guessing 400+lbs. And the 861's are still too stiff.

Have you made a decision yet?

Is Dobinson the solution?

Thanks

Durwin

No movement on my behalf yet. I have decided to keep my 7 wraps until my Eimkeith rear bumper is on and the F150 fuel tank swap has been completed. Once the weight stabilizes, I will start trying coils.
 
I ordered the Dobinson 675V last night.

Once I get them installed and get some drive time with them I will post here.

I was very close to buying the Toytec superflex but they aren't on the website right now (unless the part number changed?).
 
Definitely keep us posted on how the 675v work for you. I've been in the market for new rear coils for the last year and have been weighing all options.

I currently have the Dobinsons 137v (50mm) for the 4runner/Surf. They are very progressive 170/240/320 ft/lbs and hold weight well, but aren't tall enough with the longer LC Shocks. If they were a 70mm free height coil they'd be perfect.

Also, I spoke to Toytec about the Superflex rear coils. They have been discontinued due to low interest. Toytec recommended the OME861, but they are too tall for my liking.

I have also considered the Dobinsons 210v 182/217 ft/lbs, and reason you chose the 675v over the 210v?
 
I have some OME 861's in my garage (brand new) that I was planning on throwing on when my rear bumper and swing out finishes. After reading about the Dobinson C59-210V LC springs I think i'm going to ditch the OME and go with the DObinsons. Seems like they hold weight well and give a little lower of a lift compared to the OME 861's and ride a bit better.
 
My 3rd gen lift

After months of reading and searching I finally got my lift yesterday. Sharing some pics here in case it’s helpful.

I have a 02 Limited. I went with Bilstein 5100, OME 906 in rear, and I found 99’ front coils set to the 2nd perch on the front shocks. Car went up about 2”. Really happy with the results.

Good to know about the Toytec coils, too bad they discontinued them.

I really just wanted to see what kind of height the 675v will give and I wouldn't mind dropping the front down to less than 2" of lift so I need a shorter rear coil. I'm hoping the 675v is the shortest coil with enough free height to stay in a full droop (I have extended bump stops in the rear). But I'm also trying to hit that sweet spot of adequate height to stay off the bump stops under normal driving conditions.

This pretty much sums up why I started discussing this with Adison. Low lift, long coil.
 
I actually started with the C59-137V coils. If you are looking for ~2in lift or a HD coil for towing or hauling they are phenomenal! I've been running them for 2.5years now and have only impressed. The ride unloaded is great and loaded the ride is fantastic.

I've run the C59-137V in three different configurations :

1. Stock rear bumper w/ hitch and with Dobinsons HD shocks:
-This setup held the weight of a hitch mounted cooler, gear and luggage packed to the ceiling, and four adults. I drove this setup from Grand Rapids to Glacier National Park, Yellowstone, and back to GR. The truck maintained approx 2in of lift and I don't recall a time I hit the bumpstops. The ride was shockingly good.

2. Stock rear bumper w/ hitch, one 10mm trim packer per side and Dobinsons HD shocks:
-The trim packers netted me a total of 2.4in of lift. I ran this setup on a trip from Grand Rapids to the San Juans, Rimrocker Trail, and Moab. I had approximately 400lbs of gear and tools. On the trails the flex was good but not amazing (due to the shocks not allowing enough down travel). Stability was spot on.

3. Heavy plate rear bumper (~120lbs), one 1.5in Daystar coil spacer per side, and LC Tokico shocks:
-Total lift ended up just shy of 4in. The main reason I added the spacers was to take up space so my coils didn't drop out with the LC shocks (I am running Durobumps 5.25in bumpstops). Without the spacers the coils were loose under full flex. I ran this on a 6,700mi three week road trip, and I would keep this setup but I absolutely hate running large coil spacers. I've run them on both my 96' and 00' 4runners and in both instances (on stock coils and the 137v) stability has taken a hit.

The C59-137V will go to my daily 00' 4runner w/ front 99 tall coils. My 96' will either receive the 675v or the 210v. I'm leaning towards the 210v.

I have a stock 99 with hitch that sags pretty bad in the rear, especially when loaded with anything. I also pull a small trailer occasionally. I want to replace the rear springs with something that supports the weight a little better but still rides close to stock as we have some pretty crappy roads around here and it is my daily. I don't mind a little rake so taller over stock 99 is fine. You say the C59-137V provides 2" of lift, what is that in reference to? Since I have a 99 that already sits taller than the rest of the 3rd gens would it be 2" taller than I sit now or something less than that?

Just trying to wrap my head around this and being new to the 4runner this whole lift/coils/everything else is so confusing. I do plan to put on a plate front bumper soon, and will likely update the front end to something similar to the Sonoran steel 1.2 kit. Maybe I should just buy the 1.2 kit and be done with it.
 
If you already have the 99' tall coils the most lift you could expect is 1-1.5in over where you stand now. They actually pair well with the 99' front coils, giving a slight rake. I'll be running them on my 00' 4runner once my my 675v coils for my 96' arrive.

As far as ride. They are only slightly firmer than stock but will hold weight far better.

But if you ever want a full 3in lift I'd just start with something like the Sonoran Steel 1.2, that kit includes a lot of little pieces that help make a 3in lift work on our trucks.
 
Also, I spoke to Toytec about the Superflex rear coils. They have been discontinued due to low interest.
I haven't talked to Toytec, but they have a spring that appears to be the Superflex by a different name. The spring itself looks identical:
99602RC-P - Toytec Rear 3-Inch Lift Coils (96-02 4Runner)

And the price is identical to what I paid in 2013. Here is the part number and description of the "old" superflex:
024RCB ToyTec Superflex Rear Coils (96-02 4Runner)
 
Toytec use to sell both the 9960RC-P and the 024RCB. While both appear to be of similar design (with a section of 'dead' coils), the 99602RC-P is a 3in lift coil, whereas the 024RCB was a 3.75in lift, and 3in with 400lbs of extra weight.

I had been on the fence for a year on which rear coils to get, unfortunately I decided on the Superflex the week after they were discontinued. My mistake for waiting so long, but now i'm in a search for a coil that will sit at 2.75-3in with 500lbs of extra weight.

I just received my Dobinsons 675v (in red) so I'll be testing those this week. If anyone is interested in the 675v, Dobinsons Direct does have a scratch and dent section. I picked my coils up for $133. They have a few nicks but they are going to be living under the truck, so stone chips are going to happen. Overall it is a great way to get $87 off a nice set of coils.

I'll report back when I have them installed.
 
Let me know what you think of the 210v. I just installed the 675v on my 96'. I measured the coil free height at 18.75in or 476mm. I netted about 4in of lift with a plate bumper. They ride really well and overall i'm impressed with the ride quality and flex.

However, I may end up ditching the 675v for the 210v. The major downside to running a FJ/4th/5th gen coil is that they have a notably larger diameter. I knew this going into this project, and knew I might run into an issue. But for $133 it was worth the gamble.

For me, the issue is that the coil is so wide that it is actually hitting my frame rail on the passenger side. The contact is in the less active section of the coil so it doesn't pop or make any noises, but it does rub. I'm not sure how comfortable I would be in the long run with that kind of contact.
 
BK9602RC Coils

Looked into purchasing a lift kit with superflex coils but unfortunately they are discontinued (confirmed with associate at Toytec).
Now looking to buy TTHA-9602 - Toytec/Eibach 3" Lift Kit, hoping for no sag and a leveled lift.
Has anyone ran this lift? Recommend it? Suggest anything else?
Thanks in advance.
