Going from OME 50mm to Dobinsons 3" Tapered Coils: What All Is Needed?

[ewillis]

Currently running 850/860 and looking forward to your comparison.

 

[Dragos80]

If I remember correctly (of course you need to check with them) for the 3" lift they recommend these shocks:
F: 26.37" - 15.35" = 11.02" travel
R: 26.77" - 16.02" = 10.75" travel

Can't remember the part number.

The only ones who can beat them in terms of travel are the OME L shocks 60070L and 60071L, within the same category.

That is our 4" shocks. Here are our 4" and 6" shock lengths.

4" shocks
GS45-912 - Front 15.35" - 26.37"
GS59-687 - Rear 16.02" - 26.77"
6"
GS59-684 - Front - 16.53" -28.66"
GS59-685 - Rear - 17.00" - 28.74"

Do you still recommend the 4" lift shocks for the 3" lift coils?

if you're going tapered you can run the 6" shocks

 

[Dragos80]

Hmmm. So they extend a lot when decompressed? Won't there be any binding in the LCA?

Just to be clear, the tapered coils are the true dual rate coils?

@David Otero would you please do a full write up in full detail these new tapered coils to make the record strait? There still is a lot of assumptions of these. It would be very nice to reference back to one place. Free height, springs rates & if you have HD options etc...

I really am a promoter of any dual rate options for the 80 series, be it Icon, Slinky, Tourflex, TuffDog, OME stock height or now the Dobinson Tappered coils.

If your talking about the front, yes, its going to be difficult to get much more total flex regardless of what dual rate you use. In this case the spring definitely won't be the limiting factor. The biggest benefit on the front side will be the riding manners of a dual rate vs linear.

@GW Nugget someone else on this forum already has these coils. I talked to them, but its been long enough ago that I don't remember who it was. For that matter I don't remember what all we spoke about other than he did say he thought the coils made a little noise. As though the smaller tapered section were able to move a bit in the spring perch.

It's @baldilocks that has the fronts & another grey Lx450 in Florida that has Dobinson down the side clading with Fox shocks.
Yes they do have a slight slinky sounds at 1st.
I'm just asking Dave to give a full detail so we don't have to go through 50 pages of hear say like the last new suspension...

 

[Lumpskie]

I may have missed it.... what are the spring rates on those springs? Also, if anyone knows, can you share the price on those taper springs? They look like a solid Slinky alternative.

EXACTLY!
@David Otero can you help us?

This is our highest end coil spring for the 80 series and we are extremely confident that it will ride and suit just right. We offer the tapered coils for both 2" and 3". We can't put out our coil specs out to the public because it's proprietary information. The price of the coils are $375 the pair shipped within the 48 states. @Mdej3 is the grey 80 running our 3" tapered coils with our 30mm poly trim packers all around.

 

[LFD2037]

That is our 4" shocks. Here are our 4" and 6" shock lengths.

4" shocks
GS45-912 - Front 15.35" - 26.37"
GS59-687 - Rear 16.02" - 26.77"
6"
GS59-684 - Front - 16.53" -28.66"
GS59-685 - Rear - 17.00" - 28.74"

Running the 3" tapered with the 6" shocks, how far do the bumpstops need to be lowered from factory location?
Also, are limiting straps needed? Thanks!

@GW Nugget By the end of December I will have the 2" new TourFlex in stock along with the current in stock 3" (approx. 320$ a pair shipped to the lower 48) and by Feb/March the 4" tapered TourFlex in stock. These will be about 25$ a pair more.

Plus 2" and 3" Tough Dog dual rate coils as standard stock options.

Once our move is over we will release a full TourFlex and Tough Dog specification chart and post it on several threads and as always the CruiserMart/ Trail Tailor website.

Mmmm... Best springs ever? Hell yeah they are.

I'm with you brother. I'd like to see a thread with all of the 80 springs, part #'s, and free lengths. Sometimes its nice to have all the eggs in one basket. Plus I think most of the consumers for these types of products want to be educated on the specs. I know Dobinsons has been a bit reluctant to share rates in the past due to concerns that its proprietary information. I understand that to an extent. However, I believe they are one of only two spring manufacturers in Australia and here in the states there's Eibach and who else ? If you had the ability to manufacture your own springs I think it would be a simple act to figure out the rates of a competitors product and duplicate them.

That said, I know David's hands are probably tied on this one. If Dobinsons marketing/management doesn't want to make the information available then that's that. From the times I've spoken with him on the phone he seems to have a very strong working knowledge of the product. If he can steer you in the right direction as far as what spring to use based on what you tell him over the phone, and it works well, then I guess it doesn't matter what the rates are.

 

[Dragos80]

Just about everybody else lists the compression rate (lbs/in).
Thats just like stating the horsepower/toque and MPG on any car. That's not proprietary information.
However, how one gets to those numbers, would be a company secret. Where the steel comes from, how it is treated, at what temperature, how is bent, etc we don't need to know.
What is medium? What is heavy? 160lb/in? 270lbs/in?

Any updates on this? I need to replace my front springs. I have Dobinson 4" flexi coils in the rear now but I am debating whether the tapered coils are worth the $100 upgrade over the flexi coils. I've been really impressed with the flexi coils so far.

I run the 3” taped coils in the front paired with Dobinson’s inexpensive, yellow shock made for a single rate 6” lift coil. The two are well matched as the free height of the coil is nearly 24”.

I have run a few different single rate coils and these tapered coils ride more comfortably in all circumsatance and they allow your radius arm front suspension to travel as far as its design limits allow.

You really can’t go wrong with these in my opinion.

I also ran a set of 4” Flexi coils up front for a short time so I could compare them and the Taperd coils. For all practical purposes, I could not tell much difference while driving on or off road. The main difference I did notice was that the tapered coils are approximately 1” taller when free and they used every inch of the 6” shock even though they are a 3” spring.

I run a 1” spacer in top of the tapered 3” coil to get the 4” lift I want. Since spring time, when I installed them, I have run around town, over the Rubicon Trail a few times and we took a 4000 mile road trip along which I spent one week wheeling in Moab. At no time have I regretting choosing the tapered coils over the Flexi’s. I’m quite happy with them and the shocks too.

Disclosure: I’m just a guy who likes to go wheeling and my comments are in no way based on a certain expertise.

 

[RFB]

if you're going tapered you can run the 6" shocks

Damn then I should be good wit h4 in springs(ty) and the 6 in lift slee(ADS) ressie shocks correct??
