Dobinsons 100 Series Suspension options - full breakdown (1 Viewer)

[riffman12]

Hey all - cross posting here for the Dobinsons experts.

I'm looking for ideally 1" - 1.5" of lift in the rear and trying to decide on the ideal springs.

For additional weight, here's what I carry:
- removed 3rd row seats
- custom drawer system that's ~150 lbs
- ARB front bumper coming soon
- half of the year I run a roof tent that's ~140 lbs
- when we go camping we add another 40-80 lbs worth of gear

On my last cruiser I had OME 2860s which are a little taller than I want here.

Would the C59-167 be pretty much the same as the 2860s?

Would the C59-185 be better? Or is that going to be too stiff when I'm not loaded down?

Not much weight , no different than a few passengers sitting on the third row .

Either way, dobisons has some info for each spring that says what amount of additional weight its rated for so you would jist by accordingly .

How does your vehicle currently ride ? you can consider sticking with OEM or a light duty Dobinsons setup. Any stiffer spring along with additional vehicle rake , will most likely sacrifice a little bit of ride quality when not weighed down

C59-185 way too stiff. I just ordered these for my fully armored 100 with a heavy 34” spare hanging off the back and dual swing outs. They are beefy af. Will post pics once installed.

Well I do want some lift over stock. My setup is currently bone stock.

C59-167 are about 5mm taller than 2860's in free height and a similar spring rate. Those would be the tallest you'd want with the weight you've got. 185's, no way.

You might want to consider C59-223V if you're trying to keep it lower.

Thanks, Mike!

I've been reading more about the 223V and it does look like an interesting option. Is the idea that it will be more plush unloaded but won't totally collapse when you add weight to it? What would be the benefit over the 159?

Do you think the 223V will handle the roof tent and rear drawers I have and still give me some lift? If so, how much do you think? I can't find many pictures of 100s that have them.

looking forward to seeing your rig with these. I'm a heavy truck: Front (w/9K ironman winch)/Rear bumpers w/dual jerry & 34.8" spare (ironman/Dobinson), Rock sliders (Icon), 24gal LRA Aux tank, Prinsu rack w/solar and occasional camping gear, 2nd battery and custom drawer/fridge/cook top, compressor. Currently running Tough Dog tourflex gold 880lb constant rate. (edited for clarity)

OME 2860 480/490mm - 220lbs/in (+2.5 stock)
DB C59-167 485/495mm - 227 lbs/in (+2 stock)
IM +2" Med Load 485/495mm - 229lbs/in
DB C59-613v 540/550mm - 175-275lbs/in
OME 2863 480/490mm - 250lbs/in
IM +2" Heavy Load 460/475mm - 274lbs/in
DB C59-185 480/490mm - 277 lbs/in
DB C59-171 485/495mm - 328 lbs/in

^ These are notes I had jotted down in my phone back when I was shopping. Ultimately went with 2860s because I believe they're the softest spring rate at the height I wanted. Gave me closer to 1.5" of lift though.

So maybe the OME 2865s would suite you if you liked the 2860s but less height.

Hey, I’m looking for 2-2.5” in the rear of my 03 LX470. I currently just have some camping gear but am planning on a rear bumper with spare tire in the next two years. I called dobinsons and they recommended the C59-175V but on their site it shows a 3” for an 80 series. What springs would you guys recommend? I’m running radflos with external reservoirs at the moment.

Since you don't have hardly any weight on it now, I wouldn't go with those. 80 series coils fit on a 100 series, but they don't lift as much because the 100 series is heavier.

The C59-167 is what I'd suggest. They'll be 2" with a 3rd row seat or light weight and 1.5" with the rear bumper. You can add rear spacers to boost the rear height later if/when you add the rear bumper, or change out the springs at that time. If you get 2.5" springs now to suit the weight, but you don't have the weight on there, you'll get like 3-4" of rear lift and it won't work out so well.

Thank you, dude. How does the flex actually compare when putting in longer coils like from an 80?

 

[offoradjunkie]

I have the OME Torsion bars but they got probably 100k miles on them and are starting to sag too. The Dobinson's ones are nice.

All of the rear coil spring options for a 100 series are from an 80 series. They just spec out differently when used on the different models due to the weight difference.

Torsion bars last a really long time, I doubt you'd need to replace yours. They usually only get replaced if they break or if they've been used really hard for a really long time.

I think my shocks are just do for a rebuild then, they feel sad and slam when i hit potholes (it was worse before I tightened my tbars even more). I have my T bars tightened up all the way currently but I am running a front bumper, winch, group 31 AGM battery, and a box full of recovery gear on my rack.

Here’s the C59-185 installed. It’s a touch higher than I hoped but not bad at all. This is with zero gear, 1/4 tank of gas, no Jerry cans, etc.

Hey Mike,
I'm ready to pull the trigger on a set of IMS for my 2003 Lexus LX470.
Which shocks do you recommend with about 200lbs in the front and rear, along with a RTT and a 2.5" lift?
And how long are your shipping times typically (SoCal)?

Another data point to show high high the C59-223V progressive rate springs sit. This is with no third row, but a ~100 lb drawer system in the trunk. Really happy with how the springs ride.

I've found that amount of rake rides well on my Tacoma and the 100. That is ideal as far as my experience goes.

How many miles do you have on those? Was looking at Radflo as an option, amongst other options.
