Dobinsons rear long travel variable rate flexi coils

[Brandon H]

Running 749Vs in the rear of my KDSS-equipped rig with the KDSS spacers. Works very well and flexes out great. I also have a prototype switch that relaxes the KDSS system on command, not just below 12 MPH. This has been a game changer so far with the 749Vs. stay tuned. As long as the springs dont start sagging like my old OME 2899s it will be awesome.

Without the drawers, the 677V would do the job just fine. A lot of drawer systems are 150LBS empty, then people tend to keep them full, so it could end up being 200-300lbs additional. You may end up needing the 701V's then, depending what sort of final ride height you're looking for.

Alright, so Mike, I did buy 677Vs but since then, I did add a roof rack. I don't have my full skid set yet, but I have a front and trans skid. I haven't even installed the 677Vs yet because I think I should just jump to the 701V.

Reiterate the weight:
Ultraswing - net 150lb increase on back end with larger tire
RTT - 150 lb
Rack - 50 lb
Awning - 30 lb
Front/trans skid + eventual transfer case - 130 lbs
Gear - 60 lbs

I do have a the winch + hybrid bumper up front, but the 352s will take care of that .

THAT SAID, I'm really just looking for a net 2.5" lift. If I'm basically carrying 550-600 lbs at any given point, am I going to get that with the 701V? Your website seems to imply I'll get the full 3.0" even with 600lbs.

The rear weight would only be:
RTT
1/2 the rack weight
A fraction of the awning weight
Gear

Front skid plates don't affect the rear.

Yes, the 701V's are intended for 3" lift with 600LBS, and I don't think you're close to that. You're at about 250LBS from what I can tell with what you've listed. I think you should run the 677V's.

Much appreciated Mike. I also have sliders, but I'm still out to that max weight by a distance since I'd split that too.

I'm going to try to get the 677s in tonight.

C59-749V - Variable Rate, 800-1000 LB super heavy constant rear load, 3" lift, long travel. 520/520mm free height, 18mm wire, 198-300LB variable rate, usually around 270LB at loaded height

What would be the negative to running these with just a rear bumper, and half weight of sliders/rack (approx 340lbs constant)? Just rougher feeling in the rear? For trips the rear would be loaded to the 700 range. Have friends with similiar setups who went 701 and then ugpraded to 749.

Is it just harsh ride? Or can damage be done?

Sounds like there is a market for a 2" or 2.5" extended travel 400 or 500# spring... I'd press buy in a heartbeat. Need a long travel spring for KDSS rigs that use the above spacers and don't have 600+ pounds loaded all the time.

The length of the GS59-701 shocks is the maximum droop travel that the KDSS system can handle. The rear sway bar can contact the panhard rod at full droop. It's the same with the stock height spring up to 2.5", so an extended travel spring wouldn't help anything in this situation. It's limited in travel by the shocks.

It would give too much lift. That's why there's 4 different springs set to 3" WITH the listed amount of accessory weight on there. If you run a spring that is designed for a lot of weight, and you don't have that weight, the spring won't sit at the correct ride height, and also won't perform properly because it doesn't have the correct amount of weight on it.

You need to use your daily constant accessory weight to determine what springs to choose. Too much spring isn't a good idea.

There is a few of us KDSS rigs with 600+ extra lbs extra in the rear (Bumper, drawers, roof top tent, gear etc) running extended travel shocks and 749 rear springs. The trick is to run the blackgate customs KDSS spacers on the rear. These fix that problem, and also keep the KDSS piston from contacting the Panhard bar. There is no issues with KDSS lean, nor issues flexing. Does very well. Also coming out soon is a switch to be able to put the KDSS system in limp mode (disabled) on command. Myself and one other are testing the stich out and so far has very favorable results. Stay Tuned

KDSS spacer on the front? I'm not aware there is a spacer for the front yet. Both the website and the thread here indicates it's for the rear unless you are running an as of yet unreleased front spacer

My mistake. I meant for the rear only. There is another company that is advertising one for the front, but only does one side. They claim it fixes the lean, but i haven't seen any issues yet for the lean with just the rear blackgate model.

I installed the Dobinson LT shocks last night with Durobumps on Superflex HDs. Took out some jimmyrigged Procomps for a Tacoma that gave me the travel. Lost 1/4 to 1/2" it appears that the new shocks are not soaking up but its not settled yet. Had 3.6" lift with the HDs. Seems ride is nice but will take out this weekend and test more extensively. Need to change the brake lines.

thats pretty good, I really like the flex from my toytec lift

I was saying I'm looking for a spring for those of us that don't run an extra 600lbs in back all the time. I'm aware all that exists but no point in getting the spacer if I can't find LT springs that work with less weight in the back. If you know of any please inform me. Then I can get extended rear shocks and the blackgate spacer.

I've finally decided on a Dobison IMS lift after months of racking my brain, I just have a few questions regarding the best set up for my Runner.
im currently stock v8.

in the near future have a single drawer system. 150+ I'm assuming loaded.
will have a subwoofer as well.

I would like a 3" lift and maintain factory rake.

front spring
C59-314

strut
IMS

Rear spring
C59-675v
strut
IMS long travel

will I need spacers for driver side lean? or will I first have to see if it will lean in the first place.i don't mixed it being stiffer but don't want anything jarring either.

Hey bud,

That setup would get you at 3" front and rear, so that's what I'd suggest. It's the softest setup you can get too.

A rear spacer would be recommended. The front can be adjusted by the coil seat height if necessary.

 

[Crikeymike]

There are hundreds if not thousands of guys on this forum running the Dobinsons long travel rear coils. C'mon guys, I know you have more photos to share of your rigs all flexed out. Post them up, along with what shocks and other gear you're running!!

 

[Crikeymike]

Hoping to get some additional feedback from people running the 675's on the rear. Anyone running 75-100 pounds over stock with the 675's? (i.e over sized spare tire, recovery gear and tool bags etc.)

Really wanting to stick around 2" of rear lift but want the progressive coils.
