FJ Rear Coils?

Semi new to this whole forum and my "new to me" 2001 SR5 Blue Pearl 3rd Gen. My rears are shot and am curious about using FJ Springs in the rear as an OEM replacement/ baby lift??? Any help is good help as I'm great with tools but not with cars, BUT WILLING TO LEARN!

You can find 5th gen 4runner springs for dirt cheap, found mine here or reddit, cant remember. The rears are very simple, but the top bolt is a challenge. I soaked my top bolts 4 times the day before and they came right out. You dont have to take the sway bar off either, or I didn't at least.

Curious cause I got a basically new pair from FL for free. Neighbor of my In laws had his fj lifted since new and had gotten rid of the rest of the suspension cept the Rear Coils so I said I'd take em. Possibly thinking of bilsteins but don't want to buy new rear coils if I don't have to.

Rears aren't complex, but getting to the top shock bolt can be challenging. Soak it for a while before starting, like a day or 2, with PB Blaster. Mine came right out. I didn't need to take anything other than the wheels off and used a pair if floor Jack's to droop one side while supporting the pumpkin.

Is anyone familiar with Dobinsons C59-131 and C59-297V? These are rear coil springs for the Prado 95 with 40mm lift. C59-131 is constant rate while C59-297V is variable rate. Unfortunately, I do not have info with regards the wire diameters, spring rates, and free heights of these coils.

I have had the C59-137V in for the last few years in a 99 surf. about 2.5-3" lift, good ride, but now towing the race car fully loaded up it's a bit bum down. Also have an aux tank in now too so may try some spacers first.

Shocks are by far the dominant factor with ride quality. Surprisingly the best ones I had in were the cheap Gabriel G63726 which are about .5" longer than stock. Now with ironman and not that great.

I previously posted in this thread about my experience with FJ coils on my 3rd gen.

They worked great, and I still believe they are a good option for people wanting a mild lift and better weight carrying capabilities.

I just replaced the rear coils with the Dobinsons c59-137v. Still using the 3rd gen specific bilstein 5100 shock.

Only driven around town once so far, but the ride feels softer and more flexy. The FJ coils felt stiffer. The rear is now 22 5/8" drivers side, and 22 7/8 passenger side center of hub to fender. So about 1.5 inches higher than the FJ coils had me.

I still have FJ coils in the front on the second perch from the bottom. And now I have the rake I desired. About an inch higher in the rear.

For those considering the FJ coils for their ride, I would suggest using bottom clip if running 5100 or similar adjustable struts. That should put you level and give you about a 1" lift over stock.

I was about level with the FJ coils on second perch, and FJ coils in the rear with a 10mm trim packer in each side. I wanted more rake though.

I will say if the Dobinsons don't settle too far, they are perfect for what I wanted. I was skeptical about any of the 3" offerings paired with the 5100 due to them being listed as a 0-2" capable shock. So Dobinsons with the 2" lift and progressive coils made perfect sense.

I use my truck as a daily, but also hit trails, take it hunting, take it fishing, etc. So these coils meet all my needs especially with the higher rate coils when I'm weighed down with hunting gear and an ice chest full of venison.

If you have any questions hit me up, and I'll answer them the best I can.

With the C59-137V, did you install trim packers and the conical bump stops?

 

[floatingkiwi]

Well originally I had the springs alone but am now carrying more weight on a regular basis and towing a race car fully loaded and happened to do a prado rear disc conversion recently, and got the conical bump stops too. I had had some 15mm packers for a long time on the shelf but when I went to put them in just last month I realized that they were indeed only made to go inside the prado conical bump stop, and would not locate the bare spring (a la surf/4runner) properly by itself.

So now I have a bit of rake back again and it's sitting level when loaded. I have the EFS EEHD (extra extra HD) springs in front with no diff drop. TPR-101HHDE. 2.4" lift front, and now about 3-3.5" in rear with the conical bump stops and the 15mm packers.

 

[Thepedigree13]

I just have the conical bumpstops, no trim packers. Took it through the Texas Hill Country Overland Route today, river fording, mild trails, and some fishing spots.

It flexes very well, and is comfortable through the rough stuff.

I loaded down with wife, 3 kids, cooler, fishing gear, and about 150 pounds of miscellaneous EDC tools/gear, and it didnt sag enough to visually notice. Still had rake.

I'm extremely satisfied so far. But it has only been a couple of days, so.......

I'll update this thread if anything changes.

Has anyone used Dobinson c59-234 coils to lift the rear? Looking for 5” of lift and don’t want a harsh ride.

Suspension help

Hey guys!

I just finished going through this thread and got a good amount of info about the rear springs. I recently bought a 2000 4runner and my suspension plan was to go with
-Kings front/rears
-Total Chaos UCA
-Dobinsons for rear springs

You guys have talked about the 210v on here but what about the 220v? I've seen different people run both of those for the rears. With the parts I plan to install, I want it to be enough for a future swingout bumper and a roof rack. I'll eventually look into an aftermarket front bumper but that won't be for a good while. With that being said, is the 210v or the 220v the best option for me?

I think 220V springs will be too much lift even with a rear bumper and swingout. Expect to net 1.5-2 inches of lift over 210V springs. So somewhere around 5 inches of rear lift: https://www.toyota-4runner.org/3418096-post2.html

That's what I thought but judging by the pictures they're the same size and same amount of wraps as the 210v, so I assume they're stiffer to prevent sagging and thus rated for extra weight
And if that's the case, those are probably some pretty stiff coils. My 210v are plenty strong, actually I had to throw 160lbs of gravel in the back to help them ride a better (which really helps, for anyone interested)
But I'm purely speculating. If that's NOT the case and they really are just bigger, then yeah those are some VERY tall springs. The 210v gave me like 4in before the weight (and probably around 3.5 right now with it)

220V are marketed as a 2" lift spring for an FJ80 vs the 210V which are marketed as a stock FJ80 spring so I would assume at least 2" of lift over what a 210V would get you. 220V are advertised as light load (0-110 lb) vs 210V for stock weight so I'm guessing the spring rate would be similar between the two with a taller free height for the 220V. All this is speculation on my part.

Im looking for some LC7wraps if anyone is getting rid of them. Running bilstein 5100 rears and 880/billy front on a 99. My 906s are great unloaded but now that i have a sleeping platform/drawers/500lb slides/ rack/ ect its sitting low (22in hub to fender before trip gear) obviously the 210 is out of the question with the 880 upfront (22)

Why do you say obviously? Sounds like they'd be right up your alley

 

[bmwahba46]

I'm running a Toytec Superflex rear and having some sag issues when fully loaded.

Running a heavy rear bumper, full spare swingout, and when fully loaded for camping with gear, tent, etc, I get some sag.

Is the OME 861 the answer? Need something that can hold more weight but retain the benefits of the Toytec tall superflex.

Wont the rake be ridiculous? Trying to keep the COG fairly low...

Oh my bad I was getting the 880 and 881 confused
