Dobinsons 5th Gen 4Runner Suspension options

Not the trd pro

 

Think it's time for springs! Do 302's and 505's sound about right to delete the preload/spacers I'm using with 5100s? Will be adding a slim bumper and winch.

 

@Crikeymike Good morning, are the IMS shocks built with progressive valving? Also, I noticed your website shows items on backorder, but I don't see where it says items are in stock and ready to ship. Can you clarify? Thanks

 

Yep, that's a good combo!!

 

We only show what's sold out or on backorder. Anything else is in stock, except colors of coils are not individually tracked online.

They're progressive valving, they get harder the more they're compressed

 

Thanks for the response. One more question, will the IMS 574s work with 302 springs?

 

Yes, any lift of 2" or more

 

Hey Mike, just look for some confirmation and guidance here. I'm daily driving and light to mod trails. No additional weight now. Maybe a hitch mounted tire swing in the future. Looking for 2.5" in front and level. This is what i had pulled up. I do have KDSS, do I need the spacer kit? Also I'm not opposed to adding UCAs if you think it would make a noticeable difference.

C59-302
IMS59-50700
C59-505
IMS59-50701

Thanks!

 

Hey bud

You'll probably want the C59-599 on the rear so that it sits a little more level front to back.

UCA's help with ride quality, articulation and also the alignment, so it's beneficial to run them for sure. They aren't necessary at 2.5", but there is a noticeable improvement when you do have them.

Try it without the KDSS spacers and see how it goes. If you get a lean that doesn't go away with the regular KDSS reset, then order and add the spacers in.

 

Thanks a lot! If I wanted to go 3" and level would the below be correct? Do you think there's a noticeable difference between 2.5 or 3? I know I'd def need the UCAs in that case.

C59-314
C59-325

 

The C59-314 lift a little more than 3" with stock weight, so it's better to run the C59-302 coils and change the preload on the IMS to get to 3".

For the rear, C59-505 are more like 2" with stock weight, so I'd run those instead of the 325's.

 

Hi Mike -

I put these rear coil springs on my 4runner trd pro offroad
Dobinsons C59-505

I have already this ladder on and now planning to add a metal bumper with a wheel mounted.

Wheel + Tire = 70 lbs
Ladder = 20 lbs
Bumper = 150 lbs

Total Weight = 240 lbs

Will this spring be OK ?
The bottom mounted wheel will come off, so probably less than 240 lbs of weight on springs

It will look like this.



Thanks for your help.

Best Regards,
Naeem

 

Hi Naeem,

You can run them but they will squat down a fair bit when you add that bumper. Probably about 3/4" lower than your current position, so you'll probably want to upgrade to the stronger spring rate. Most people run the C59-327 coils when adding a rear bumper like that.

Thank You!

 

Hi Mike,
I'm currently running Fox 2.5 DSC w/ 505 Dobs rear springs sitting nicely at 24.5" from mid hub to fender w/ full under armor, sliders, and roof rack. However, with rear swing (tire/drop down table) 200lbs of gear, my rear drops down to stock 22" mid hub to fender which is expected. I'm now planning on an Ikamper RTT which is 160lbs. Would I be benefit best from the 327 or 329 to keep my rear at 24.5" with everything. Thanks alot.

 

Hey bud,

If you had a full rear bumper then I'd say the 329's, but since you don't, the 327's should work fine for you. It will be somewhere between 24-24.5" loaded, probably more like 24".

Or if you think you'll keep building and adding more weight, you can go for the 329's. They sit at a similar height but are a stronger spring rate.

 

Thanks so much for replying Mike. Just another quick question, how much lift would I get out of the 327 if I'm not loaded (200-400lbs constant) I don't plan to leave my swing and RTT on 24/7 since my runner is a daily, would 2.5-3" the amount I'm expecting?

 

They're 2" with 400lbs, so with less weight, they'll sit higher.

 

Hey @Crikeymike -

I'm about to pull the trigger on parts needed to redo my front suspension.

I have a 2018 SR5 Premium. Currently, running 5100s stock springs, stock UCAs.

I'm going to be installing Baja Boss - 255/85/17s next week.

I am planning on getting UCAs, shocks, and springs.

Currently, the front of my 4Runner has a second battery, ARB dual compressor, full-length steel skids, steel sliders, LFD low profile bumper w/ winch, and an aluminum roof rack. About 210 lbs plus the sliders and skids.

3 questions:

Which springs?

• C59-352 – With 220-300lbs – 2″ | Heavy rate coils
• C59-354 – With 220-300lbs – 2.5″ | Heavy rate coils

Which shocks?

Extended travel vs regular travel
​

IMS struts vs MRA struts?

Sell me on the MRA struts. They are double in price... are they worth it? I do a lot of Baja driving, open desert driving (Johnson Valley, Anza Borrego) and mountain fire roads. ​

Thanks!
Cory

 

Hey bud,

You didn't say what lift height you're looking for. The extended travel are for 2.5-3.5" of lift primarily, so if you want that much lift, you need to go with those. If you want less, go with regular.

They're the same spring rate, just different lift heights, so it depends what you want.
We also break down the front end much simpler with coilover build pages here:

I wrote this up talking about the different shocks:
https://exitoffroad.com/different-shock-types/

I also have a few videos on my Youtube channel about the shocks and what goes into them.

If you've been doing all that sort of driving on 5100's, then you've been missing out!!

 

Thanks! I just pulled the trigger on the MRA shocks. I went with the C59-352 springs. Hopefully, the height is right. I figured they are cheap enough, I could always swap them out later if I decided to.

I currently have your extended travel monotube shocks in the rear. I'm worried upgrading my front shocks to the MRA is going to make me want to swap out my rears.

 

Hey @Crikeymike, need some guidance here…

I have a 22 TRD ORP on tuned Kings with full rear bumper, dual swingouts, roof rack, RTT, 35’s, full skids, sliders, and homemade drawer system. I’m currently on Icon Overland springs in the rear and they just feel soft. I was thinking the 701V’s would be right for me but I want to know what the ride height is with 500ish pound constant load. I’m wanting to stay around 2” - 2.5” loaded height.

 

They're a 3" coil, so 25" from hub to fender. The 701V are the next step up from the Icon overland springs which are more like the 677Vs.

If you only want 2-2.5" then you'll need the C59-329s.

Hey @Crikeymike,

I have a 2021 TRD ORP, nothing added as far as weight goes, will likely add sliders and roof rack but unlikely any bumpers, etc. 99% on road usage. Looking for about 2-2.5" lift and leveling to fit 285s. Would a set up with 302/505 front and rear serve me well or would I be better off with 302/599?

Also, I see that the 700 shocks are on backorder. Wanting to order everything with the fronts preassembled. What kind of timeline am I looking at if ordered in the next few days?

Thanks,

Jeff

 

Hey Mike, I DO have 5100's with Dob 302 front coils. How would the twin tube nitro's compare with 5100's?

 

Hey bud

GS59-700 are due sometime past July. They haven't left the factory yet.

Use 302/599 for a more level stance.

 

They're much more comfortable because they aren't a high pressure monotube shock with digressive valving. 5100's are firmer on the road for sure.

 

I need help guys... Front C59-302/GS59-574 Rear C59-325/GS59-705

I still feel like the rear is way higher, I was thinking of going to C59-314 on the front in hopes it levels everything out.

Notes... I don't have any extra weight add it on the front and suspension is been on for a couple years now.

 

Looks lovely to me!

 

Hey bud

Can you measure from the center of the hub up to the fender edge on the front and rear? That will show what actual lift height you're at.

It doesn't look off to me based on the part numbers you have installed. Gotta be careful running the C59-314 on the GS59-574 struts with no added weight, as it comes up to 3.5"-4" in some cases, which is just too much. Lowering the rear may be a better idea.

The measurements will help guide the next step.
