Dobinsons Suspension - 4th Gen Options

[Crikeymike]

Hey Mike,

I am currently running c59-350 springs with GS59-220 struts. I have a steel front bumper with winch on my 2008 v8 4wd. I am going to be moving back to a factory front bumper with a low pro bumper and winch which should drop my front end weight a bit. Sitting next to other 4Runners with 3" lifts I feel mine currently sits a tad lower than others at 3" but at the same time feel the 350s are quite stiff. I am looking at going to the 314 or 302 when I move to the lighter set up. Can you give me some advice or input on which spring you would go with?

Im also running JBA UCA.

Hey man,

Sorry, I didn't see the notification on this post.

I'd suggest you wait and see how it rides when you change the weight as it might not be too bad.

If you do want to change, I'd recommend the C59-302 to maintain a solid 3" of lift.

I've had V8 guys before though run the stronger coils (C59-350 and 352) and like the way it rides, so it comes down to personal taste really.

Yes, it could be the shock (possibly damanged) or the coil (not seated right, excessive movement). You'd have to take the shock off to isolate if it's that.

It's possible for coils to get junk trapped on the lower spring set below the coil, causing metal on metal contact. That might be something to check out, depending where you live and what sort of stuff you've been driving thru.

After listening to the noise a few times, it does sound like metal to metal high pitched squeaking. Going to do some maintenance this weekend so I’ll take a closer look on the lift. Just to make sure, is the rear shock installed correctly?

Bushing don't look compressed enough. It should meet the outer edge of the washer. If I had to guess. The stud of the shock is touching the metal mount

Thanks for the input! I’ll tighten them up more.

I'd suggest you take them off and lower the shock to inspect the shaft. It would be shiny metal if it was metal on metal contact. Then you can make sure the centering washer (with the lip) is facing upwards in the mount properly, then tighten it down.

Got it tightened up and the noise is gone! I was checking the rear shock lower mounts and noticed that the paint chipped off and saw some possible rust. Is that type of wear normal?

Just updated the full kit pages to allow the option to select twin tube, IMS (Internal reservoir Monotube Shocks/Struts, no external resi), or MRA (3-way adjustable w/external resi) in the drop down menus. Not long now until these new struts and shocks start to arrive!!

I'm probably gonna sound clueless, but just to be safe, in my box for my rear shocks for my 2007 4runner (GS59-705), I received two bags, each with a set of 2 bushings and washers marked, "for Toyota Fortuner." Just wanted to check and see if these are in fact to be put to use on my 4runner, or if they're only used on that other vehicle. All the top bushings and washers are already attached on the shock. I've attached a picture if that helps. Thanks!!

It's a good question. You will just use the bushings on the shocks. Match the bushing orientation to the way the original shocks are removed.

The Fortuner ones are for the Toyota Fortuner, a different smaller SUV sold overseas that uses different size bushings and washers.

Got them installed last week. Here is the one pic I've taken so far. As you can see, Shrockworks front bumper. It's 24" from center of hub to bottom of fender front and back. The ride quality is awesome, though I was coming from a very tired 100k+ miles, stock suspension. Here is what Mike hooked me up with for those that are interested. Highly recommend Mike and Dobinson's, he was super helpful I basically just told him how I use my T4R and what other mods I have done and he will help configure what is just right for you.

Mr. Eeks, I like your suspension! I couldn't find your signature with the kind of 4runner you have. Is it a V6 or V8 ? I would like this same look but have a V8. How does it ride for you? How do you use this ride?
What ended up being the total lift front/back ? Thanks.

I finally got around to installing my lift and so far I really like it. Below is what I installed on my '07, V8. Tires are 275/70/17.

Front:
Coils, C59-350
Shocks, G559-220
Diff Drop, DD59-527K
Dobinson's UCA's and Ball Joints


Rear:
Coils, C59-677V
Shocks, GS59-701

My C4Fab bumper'ette' and winch are still on the way and the rear is pretty much unloaded. I spec'd the coils to this additional weight so I'll do some more measurements loaded and after the coils have settled. Distance from the center of the front wheel to the fender is 23" and the rear 24".

I just am not seeing part # C59-350/ ? what say you mike? Crikeymike ? https://www.toyota-4runner.org/member.php?u=148378. using all sources to solidify a choice, but this part number not listed?
Thanks if you all can help.

It's just not as common. Dobinsons makes a lot of different coils and sometimes we pick one to suit a customer specifically.

It was a part number that was available when I bought the lift. This was 2 years ago and at that time the Dobinson stuff was new to the US. At that time I believe there were only 3 front coil options and maybe the same for the rear. Not long after I got mine two more rear coil options were available.

Installed my 701v rear coils this past weekend. Have only driven the runner for a few miles around town but what a difference. It's handling the weight of my rear end perfectly. I'll be taking it out to the dirt this coming weekend and if I can stay off my bumps while fully loaded I'll be one extremely happy person.

What made you choose the 701v? I am currently thinking about the 749v with a 850lb rating vs the 701v with a 600lb rating.

When I first got the rear bumper I tried the Metal Tech 3" heavy LT coils. They worked fine for the crawling trails we were doing at the time, but I soon found out they weren't working too well for high speed or really rutted/washed out roads. So I switched to the Dobinson 677s thinking that the static 400 would work better than the MT LT coils. Turns out they were about the same. Still couldn't handle the weight. After doing some rough math I figured I was around 600+ loaded with gas, swingout, 35" spare, water, camping gear, roof rack, gas skid, etc in the rear. So decided to give the 701s a run. I don't have a RTT, and never will, so I think the 749s would just be overkill. I'll find out this weekend how they work out.

Doing a trail to camp with a mix of high speed, slow speed, rocky, rutted, etc. It's my shakedown trail that I use every time I make major changes to rig and I know it well. Doesn't change too much unless it's been particularly rainy. Just ran it in November and there's barely been any rain since.

Thanks for the reply, please let us know how the springs work out on your trail run.

had the same thing happen to me

Very informative, thank you!

 

[Drunner97]

Holy shit what a huge difference off road. I was hitting things faster and harder than I would have liked because the rear is finally about where it needs to be. Next up will be a shock tune but I'm super happy with the 701s handling the amount of weight I have in the rear. Hit the bumps a couple times, but it wasn't nearly as harsh as it was before I did the coil change.
