Jason, does Tough Dog offer any longer 80 series specific shocks? Like approx 28" or close?

Measurements:
Front shock
Compressed 16.25" Extended 25.75"
Rear shock
Compressed 15.50" Extended 25.50"

Yes, my extended 41mm bore foam cells are close to the 28" lengths. I'll be at the shop tomorrow and will post those measurements for you.

Shocks listed above are for the up to 3" standard TD lifts. The TourFlex coils require the longer shocks (10" stroke as well).

Rear 15.03" - 24.80"
4" lift shocks

GS59-685 rear - 17.00" - 28.74" (Rec BS 3")

BUMP STOP RECOMMENDATION
(As per David Otero @ Dobinson)
4" lift shocks:
GS45-912 needs about .5" of bump stop extension with a minimum of 525 coil length
GS59-687 needs a 2” of bump extension approx. With a 505mm minimum coil free height to stay trapped.
6" lift shocks:
GS59-684 needs about 1.5” bump stop spacing with a minimum coil length of 570mm
GS59-685 needs a 3” extension and minimum of approx 555mm coil length to stay trapped
~~~~~~~~~~~~~~~~~~

The 4" lift Dobinson yellows are a bit longer than a OME real L shock.
(Hmm... Also notice there is a little play room to stack additional washers to change shock length)
View attachment 1584673
I have been told the Dobinson yellow shocks are softer on compression & slower on rebound compaired to the OME L shocks.

Dobinsons 4" Flexi Coils

@Nay added these comments in post #92:
Hopefully adding something useful this time. First @GW Nugget is right - the color scheme is meant to be:

It’s like adding teenage girl nail polish to toxic sea foam.

Second, the free height of the 4” Flexi rear coils is almost 23” - that spec was missing in the original post. Having seen the rears in person now I have also ordered the fronts.

@Nay added these comments in post #139
Dobinson’s front 4” Flexi installed. This coil is shorter than the rear, about 22.5” free height. Way more coil than the front can use in any case - I dropped the whole front end on both sides to the stretch point of the brakeline, leveraged out the old coil with a 4’ bar and kick method, and then used compressors again for the Flexi.

As compared to the FOR Gen II it replaces.

I’ve picked up about an inch of lift at all four corners. I’m right about 25.5 hub to fender (no flares), wrapped around the tire. I’ll measure more carefully tomorrow in the daylight.

Ride quality for my relatively light rig with the Fox 2.0 remote reservoir shocks is outstanding. The front feels pretty much the same outside of what I think was some coil damage from my accident - the front driver’s got torqued pretty good with frame bend and a bent radius arm and it had lost about a half inch of height.

It’s the rear that feels like it has more control - there is a lot of extra coil and it feels extremely well dialed. This seems a shift in rear coil design philosophy, more than just “longer shock”.

Definitely a clean 4-4.5” lift and seems very well thought out and executed. My 37’s are going to look a little bit small now. The coil color, OTOH, is perfect.

Gary,
Looking at the Dobinson 2" Flexi specs, something is not what I would expect.
I know it is not your fault, you copied the info provided to you.
C59-223V seem to be almost on par with OME stock height coils. They seem to be very short for a 2" flexi coil. A free height of 455/445mm or 17.91/17.52" with only 9.125 turns and a weight rating of 205/245 lb/in

OME 862 are 470/460mm or 18.50/18.11" in free height, 9 turns and 170/260 lb/in

The 3" flexi seem to be a better fit for the 2" front flexi coils, or the 2" tapered.


Is there any way we can have a confirmation on this info?
They seem very short, more like stock height rather than 2" lift and above all flexi coils since there is a lack of steel to make them long enough to drop more than others.

Looking at Dobinsons coils on Amazon it says the C59-223V is a Variable Rate coil that will give 2.0” of lift with 220# of constant weight. But with the specs on those it almost seems impossible to get 2” of lift off a 17.5” coil!

I have found 5 different rear variable rate coil numbers, providing lift, thru researching:
-C59-269V-2” lift with stock truck weight
can’t find spring specs

-C59-223V-2” lift with 220# constant load
205/245#@17.5/17.9” ht

-C59-175V-2.5” lift with 220# constant load
205/245#@18.3/18.7” ht

-C59-613V-3” lift with 180# constant load
175/275#@21.25/21.65” ht

-C59-615V-4” lift with 180# constant load
150/275#@22.45/22.8” ht

I would label the 613V and 615V coils as “flexi coils” with the 21”+ free height.

Looking at Dobinsons coils on Amazon it says the C59-223V is a Progressive Rate coil that will give 2.0” of lift with 220# of constant weight. But with the specs on those it almost seems impossible to get 2” of lift off a 17.5” coil!

I have found 5 different rear progressive coil numbers, providing lift, thru researching:
C59-269V-2” lift with zero extra weight———can’t find specs
C59-223V-2” lift with 220# constant———205/245#@17.5/17.9” ht
C59-175V-2.5” lift with 220# constant———205/245#@18.3/18.7” ht
C59-613V-3” lift with 180# constant———175/275#@21.25/21.65” ht
C59-615V-4” lift with 180# constant———150/275#@22.45/22.8” ht

I would label the 613V and 615V coils as “flexi coils” with the 21”+ free height.

I can tell you right off that those coil load ratings are not correct. The V at the end stands for variable which means they are not a constant rate coil. @David Otero for the clarification !

The way I displayed the info might have made it confusing. Edited. I got all the coil specs from Post #114 of this thread and cross referenced with the coil info that Dobinsons supplied on their Amazon page. I do know they are all Variable rate coils. I’ve been looking at getting either the 2” or 3” flexi coils.

 

[GW Nugget]

Yep, those are the specs that @David Otero gave me.
If you want to run a longer shock for more flex... the 2" rear Tapered C97-147VT @ 535/545mm would be the better choice.
It is 90mm taller in free height.

That's a better one than the flexi 2" C59-223V at 445/455mm

 

[GW Nugget]

As far as specs... we are fortunate that David stepped up to provide the specs we now have.
With the experience of some members here on mud they can look at wire diameter, turns & free height & can tell if something doesnt jive... but that is not me. If @David Otero looks into it & corrects the listing then I will correct it on my end here.

Hey guys,

The 2" variable rate coils were designed as just 2" progressive coils not designed for longer travel in mind. The only coils we call "flexi" with Australia are the 3" and 4" coils. The 2" variable rate coils are in our 0-2" catalog page listed with the linear coils as well for just normal travel setups.

So, should I just list them as dual rate rather then "Flexi"?

 

[duggy]

Has anybody run King shocks on the Dobs Flexi coils? I am on Kings shocks with comp adjusters and OME J springs. I'm planning to get the King front and rear bump stops also, but would most likely get Dobinsons flexi coils to test them out. The ride right now is actually really nice, and the springs stay captured when wheeling, so if there isn't a huge difference in ride and weight carrying capacity, I may stay with the J springs.

If it ain’t broken then might be best to not fix it. If the weight is correct OME springs are fantastic. A lot people complain about OME but don’t have the correct weight for the setup.

 

[duggy]

I'm on the same train of thought, but there's another side of it; Dobinsons are starting to gain traction on their flexi coils and customers are asking about my thoughts on them. Without any real world experience, I can't honestly provide any facts on them which is why I wanted to try them on my personal rig. The vehicle flexes very well on the trails, and the ride height is exactly where I want it, with the static weight I'll be carrying. I'll be keeping my eyes out for anybody that's run the Dobinson's setup with Kings.

 

[David Otero]

Yes just under variable rate.

Well if you sell them then that's a whole different story. It would be very helpful to know your exact weight per axle from the weight station.

 

[mjeckell]

The free height of the Dobinson 3” tapered are the tallest.

Not for the rear - the 4” Flexi are longer at almost 23”. Below is compared to the 3.5” F.O.R. Gen II coil it replaced. There are 5 dead winds on this rear coil - it could handle a bit over a 30” extended length shock without unseating. @GW Nugget this may be useful on the specs post as you only have my front 4” Flexi pics.
