Spring set up for heavy weight?

My T4R is a V8 Sport with a steel front bumper, heavy duty rock sliders and I'll usually have my camping gear loaded up when I'm headed to the mountains. I plan on getting a swing out spare rear steel bumper sometime this spring or summer.

What springs do you guys suggest for heavy weight?

Old Man EMU?
Toytec HDs?
What else?

Look into Dobinsons Suspension... lots of options available and Mike is great to deal with. There’s a thread about Dobinsons in the 4th Gen section.

i have OME with 886 springs up front, with a demello single hoop, winch, compressor, and 31m Odyssey battery(65lb or so). Out back i have OME with 895 Springs with no weight and it rides perfect, once i get my rear bumper i will upgrade the springs to 896.
 
Check Out The ARB Application Guide

Its easiest to guesstimate how much additional weight in bumpers and rails and carrying load since thats how they determine light medium and heavy spring rates..
Vehicle Application Guide
 
Metaltech long travel rear coils are pretty sweet. Seem to do well under weight and they are dual rate which is pretty cool if you do some reading on dual rate vs progressive vs linear springs. I think you can get them with 2" lift and I know they come in 3" lift. They did some revising of their part numbers and their website isn't 100% clear on the lift amounts for both springs they have.
 
I've got Icons with 700 lb coils in the front and I'm putting 3" Metal Tech heavy coils in the rear this weekend. Waiting on my shocks to get back from a rebuild so I won't know how it rides with the rear coils until then. The 2" Metal Tech medium coils were perfect until I threw the rear bumper on and then I lost some height because of all the weight.

Here's what I'm sporting weight wise:

Demello Front single Hoop + Smittybilt X20 winch (steel line)
Custom rear bumper with swing out (180 lbs + tire weight)
Steel RCI IFS skid
Aluminum RCI Mid and TC skids
Steel RCI gas skid
RCI Sliders
Dual batteries
Prinsu Roof Rack

When camping add on:

Indel B 51QT Fridge
10 Gals of Gas
8 Gals of potable water
Tent
2 cots
2 chairs
case of drinking water
case or two of beer (depending on length of trip)
recovery gear
tool bag full of tools
spare parts
small child
tub of kitchen/survival gear
tub of sleeping gear
Misc random other shit to be have fun camping
fire wood (2-4 bundles)

The weight adds up quick. I've been more than happy with the 700s up front and the Medium coils always rode a little stiff unloaded, but they couldn't handle the weight of the bumper+swing out+spare tire. Unloaded it was kind of okay, but once I threw all the camping gear in, it was just a tad too much.
 
I would like to un-recommend the OME 896 coils as they have started to sag on me after 1 year. I carry about 300lbs + a steel bumper + rear winch and you can tell that the springs are getting lower and lower in the rear. I will be looking to get something that can both carry the weight and not need a 1.5" spacer on the driver side.

Metal Tech has a driver side specific rear coil.
 
Another vote for Dobinson. They don't have a one size fits all coil, they have many options if you're the type to dig in and really optimize for your setup. They have multiple long travel versions to compete with metaltech long travel if your shocks are long enough as well as a bunch of shorter straight rate coils if you want to go that route.

I used 675V for a while and they rode great but only gave me the lift I wanted unloaded (around 2" lift) I only have heavy sliders and alum roof rack, stock bumpers. But when camping and loaded up to the gills I needed the 677V to get the back up to 3" lift and handle the extra load on trails. A little stiff for empty daily driving but man are they great on trips.
 
I'm running the Icon Overland 3"(unloaded)/2"(loaded) springs in the rear and 700lb springs for the front. I'm running everything Drunner97 is, but all my skids are steel and I have CVT RTT and will soon be putting in a Trekboxx drawer system. I actually thought about finding out if anyone that makes a 4"(unloaded)/3"(loaded) spring, but then everything would be too high so going to stick with them.

I think [MENTION=117408]Oneluv13T4R[/MENTION] is running a 3.5 All Pro coil in the rear and he's sitting around 2.5-3" loaded.

+1 for Dobinsons springs. After trying out Icons, Radflos, and Metal Tech springs, the Dobinsons springs have been my favorite b/c they hold my weight without sagging, give me a nice lift in the rear, and drive comfortably when both loaded and unloaded.

To find the best springs for you, figure out how heavy your rear is going to be fully loaded (bumper, camping gear, spare, things on the back of the roof, etc.), then find the Dobinsons springs that can handle that weight.
 
My toytec superflex gives me rake when unloaded and sits level when loaded down for camping.

Yeah, my Overland springs give me a SLIGHT rake when unloaded but when all loaded up I do have a reverse rake. I can only imagine what it will be like if I put a drawer system in. And I can't turn my fronts down too much more so left an email with Mike at Dobinsons to see if the 701's would be good with my rear Icon 2.5 CDCV struts.

Well like [MENTION=123332]Drunner97[/MENTION] I do have the All Pro 3.5” Springs and like you I also have the Icon 2.5 w/res .... but I also have a Daystar 1.5” spacer on top the springs =5” lift. .....and I also got wise after a long period of dealing with what you are now ....and added airlift bags. After much research of all the different bag sizes and brands I ended up with airlift’s 10.5” tallest/biggest bags they make.
BAM!! Add a little air 5-35psi Solved every issue I had been dealing with rather it be unloaded, loaded, weight all on one side, full or empty tank of gas, Toyota lean, ride quality pavement daily driving, and off pavement wheeling ...etc etc for less than a 100 bucks brand new.

Unloaded from floor to top of wheel well I sit 43” even/Level front to rear all four at 43” @5psi
Note:remember I also have a rear bumper with a 35” spare and hi-lift that stay on my rig at all times which for me I still consider (unloaded).

Loaded I go from 43” down to 41.5”ish 1.5”-1.75” rear height loss. @5psi

But with a flick of the switch .@35psi ..up she goes and ride quality is back! no rear weight Ass drag. And weight get distributed evenly instead of all on your rear end like an anchor.

Note: but i also haven’t heard anything bad about Dobinson’s Springs neither.
The only personal -1 point for me is that damn Turquoise color they use.
Petty yes ...

I'm running some heavy Dobinsons springs and love LOVE them. Fronts are remote Resi with their C59-350 springs and rears are C59-677v .. I couldn't be happier. Ive got a metal front bumper, sliders, RCI skids on the front and also diff, rear tire carrier , SnoMaster fridge, and rooftop tent. I've got a winch too just too lazy to install until it warms up lol

Here are some pics

They just updated this last December that that they now offer 3 colors for their springs, they now also come in red and black!

"EDIT: Update on 12/15/17.

Bring on the kicking and screaming from those who have already bought.....

Due to popular demand and an amazing amount of requests, we have brought our most common 4Runner (and Toyota) coils to the US in 2 additional colors. Red and black. Now these part numbers are available (depending on stock) in classic Dobinsons Teal, TRD Red, and/or Black, depending on part number.

C59-300 (Teal, red or black)
C59-302 (Teal, red or black)
C59-314 (Teal, red or black)
C59-599 (Teal, red or black)
C59-505 (Teal, red or black)
C59-325 (Teal, red or black)"

Finally found your post with pics and your Runner is awesome, pretty much sitting the way mine was the day I got my Toytec lift installed (w/out weight or my Shrockworks front bumper). Now I have the bumper on and the Toytec 'Ultimate' 3" lift is a joke...it's sitting just about back to stock height. My plan is to get a CBI swing out bumper sometime this summer. I'm in Denver as well, it'd be great to meet up and check out your Runner in person...maybe even wheel a bit.

I would think a bumper with larger spare would be part of the loaded weight since you are adding from stock what the normal springs could handle. You could deduct the stock bumper weight but it still is added weight that has to be accounted for.

Oh...and Dobinsons come in black too now. And some even in red! :-)
