Help with Rear Springs with a Metal bumper and swing outs

[rlarroque]

Hello everyone!

I'm ordering a steel bumper with swing outs that weighs about 200lbs, with the addition of 2 jerry cans, and a spare tire sitting on it. I try to keep as much as I can in the vehicle like tools, recovery gear, emergency supplies since I have a smaller condo I live in. I do load in camping supplies, cooler and tent when I go out. With that being the case I was wondering if anyone that ran anything similar could give me their thoughts on rear springs and what they ended up going with.

If it helps I'll be running king shocks with extended travel. Sadly no long travel for me I don't see myself needing it for the things I normally do.

Yes I know there is Google and a billion pages worth of stuff on the forum, just wanted to see if I could get some answer with people that are already running it where I didn't have to dig through all the comments to find some decent answers.

Cheers!
Rico

Hi Rico,
You're going to have to wade through a lot of posted comments somewhere. Either here or on any number of posts about rear springs.

What height of lift are you planning? Who are you buying the King shocks from and what do they offer?

Try reading this page for more info on springs:
SPRINGS « King Off-Road Racing Shocks, Bypass Shocks, Adjustable Coil Over Shocks, Air Shocks, UTV Shocks, Jeep Shocks, Pre-Runner Shocks, Adjustable Shocks, and Bump Stops

Or here:
ICON 4Runner Coilover & Rear Springs - ICON Vehicle Dynamics

Or study this:
Rear Lifts

Here's a source near you:

Look through the websites of some of the sponsors here.

Eibach (sp?) also makes springs.
Or do a search for rear springs.

You'll not want to run the Jerry cans except when you absolutely need them. Even just the spare on the swing out is a PITA.

I run the Icon overland springs and they deal with the weight well enough. I'm not sure there's anything off the shelf shock wise that is going to work well. You'll need valving specific to the weight you are running.

Hey Jeremy,

Thanks for responding. Why do you prefer not to keep that stuff on the vehicle? Is is purely for maneuvering around town or is it because if the swing out itself? The bumper is going to be a dual swing out in this instance.

I’m not too worried about the valving I can get the dialed in with the shop I’m working with. They gave me some recommendations on the springs, but I wanted to ask around and see what you guys thought of the springs you are using. I know springs can be tricky and people have gone through multiple springs before they are happy. Just trying to make an educated purchase. I’ve done a lot of research but I wanted to check with you all here

I run Icon. I started out with the standard spring, then immediately changed them for Icon Overland springs (3”) immediately after I put a full rear bumper on. I can run 2 full Jerry cans, a spare and tools. Plus, a full load of camping gear and tools, while pulling a trailer, with no problems. When I’m empty, it’s just fine as well. If your going to run what you mentioned, get an overload type spring and be done with it.

As for full Jerry cans, they’re freakin heavy and it’s a pain to swing the carrier open and close. That’s why I run them empty when I don’t need them. If you’re keeping them loaded for “what if”, then it’s about comforting, not comfortable.

u need to think long and hard about adding that much weight if its your daily driver, your gas mileage and acceleration is going to go to poop. Its cool to own a fully built rig, but it kind of sucks driving it everyday. Also, you will get a lot of attention both from enthusiasts, and from people you don't want attention from. I did what you are planning, and now I'm taking it all off, lol.



but to answer op question 650 to 7o0lb springs.

Thanks for the answer to the rate. It's not my daily driver and I also work from home so I don't have to travel as much as others do. I'm lucky in that regard. It has become my project / adventure vehicle. I have a Mustang for when I want to go fast I'm ok driving around a little piggy when I use the 4Runner.

I don't plan on running the Jerry Cans full, they'll be empty until I know I'll need them when I go out on a longer trip. And if they don't get used that'll be my next fill up lol.

Good to know about the Overland springs from Icon that was one of the options that was presented to me. When you run empty with just the bumper and such does it ride any harsher? Or does the weight of the bumper help with that?

Thanks for responding!

The Weight of the bumper, tire and what not, is plenty. It’s not harsh at all. I drive mine daily and don’t mind it at all. I realized going into this that it gets truck gas mileage, and drives like a truck because, well... it’s a truck. Good luck and can’t wait to see pics.

I am running the OME setup and just installed the 899 rear springs that are rated for a constant 880lbs. Seem to hold the weight really well and provide the 2.5 - 3 inches of lift.

How much weight do you carry on them? One of my concerns with OME springs is that everyone says they are stiff as shit and gives a harsh ride even with the weight on there. How has the ride been since you've installed those?

Im running a CBI bumper with swing out and dual jerry can holder. I have the OME 898 springs and they are not enough. Its fine for use with no jerry cans or little to nothing in the back but with full jerry cans and camping gear they are soft, very soft. I am planning to upgrade for the 3rd time to the OME 899 springs. Dobinson is my other option for springs but I can get the OME 899 local with no shipping so its hard to pass that up.
Its not just the weight you have to think about but also how far back from the axle that weight is positioned.

Yah that's one of the things I've been looking into and another reason I posted on here. I figured people have had real world experience with the weight hanging off the back. Thank you for your super helpful response!

I run Dobinson's 677V's and I'm guessing we are waiting for the same dual swingout bumper that is soon to be completed!

I went from Toytec HD Coils to Dobinson's 675V's. Those 675V's were progressive rate coils, but just couldn't hold the load when I added a Trekboxx cargo system into my rear (250lbs plus ARB fridge). I then went to the 677V's (also progressive rate) in anticipation of the new dual swingout rear bumper. These coils are definitely stronger, and right now I am running with no bumper and no bumper cover so my ass is a tad high.

I can still go up in springs with Dobinson's to their 701V's or to the previously mentioned OME coils. Like others have said, its trial and error...coils are relatively cheap...though they can be a pain to swap out with these taller progressive rate coils...but just be prepared to change them and then change them again and again. I'm on my 4th set of rear coils and have no problem going to a 5th if it means I fix whatever I don't like about it.

Hey Rico,

I was curious about spring rate compression from adding the weight of rock sliders to my truck, so I started this thread a while ago.

MTN4RNR suggested to check out the Dobinson's Thread if I decided to change anything out. I would suggest reading through this as well!


Best of luck!

I am running about 400lbs on a daily basis (Trekboxx drawer system 250lbs -ish, rear bumper, skids & daily gear). Loaded up with my Alu-Cab and camping gear its about 700lbs. I had the 898 rear springs on before and I felt like they sagged a bit much under daily load for me and they are rated at a constant 440lbs.

I am one of the odd ones that likes a stiffer ride but in my opinion it is not bad at all... I feel like my girlfriends TSX rides stiffer then my 4Runner.
