New Bilstein / Cognito Hummer H3 Leveling Front Shocks???

[tomp]

http://www.trailduty.com/product_info.php?products_id=486

Anyone ordered these yet?

Seems to be a better priced option than doing the Truxx leveling kit, which is more expensive. However, the Truxx kit would allow you to not have to worry about finding future extended length shocks and give you more shock options.

I guess since no one has resonded, the new guy will chime in. I have had these on my truck since January. Basically, I cranked the stock keys(I am running about 23.25 inches on the front end) installed the shocks, and had the front end aligned. I love them. Very nice ride. No body roll in the corners. I bought them straight form Cognito Motorsports as they are fairly local to me. Very easy to install.
Chad at Cognito explained to me that they are an existing part # from Bilstein that they take and add the lower mounts to. I liked this as it will be easy to replace if the need arises.
I do alot of dirt road running and these make the ride great. Hope this helps.

[HUMMJAY]

I bought the TRUXXX kit, had it installed, hated it for 6mo., then had it removed

Hummjay - what did you hate about the TRUXXX kit?

[Desert Dan]

With the extended shocks what happens when you bottom out?

W/O extending the bump stop the shock is going to take a beating.

Any thoughts?

[MtnHmr]

Desert Dan,
I asked that same question when I purchased. The Bilstein's actually compress to a shorter overall length than the stock shocks by about a half inch and are longer overall by several inches when extended. I verified this when I was installing. Hope this helps.

[HUMMJAY]

Hummjay - what did you hate about the TRUXXX kit?
I just thought it road like chit,,, when breaking the nose would dive, when accelerating the nose would take off,,,,, when instaled to TRUXXX specs it made the truck look like it was walking up hill, also the techs could never really correct the camber on the front tires and 35" procomps arnt cheap,,,so I learnd my lesson with cheap lift's :twak:

[tomp]

The problem I saw with the Truxx kit is that their shock extension lengthens the shock too far. This is due to the type of shock mount the H3 has and not Truxx's fault. There was no way around it. What this means is that you have to crank up the TBs too far to benefit from the extensions. Once you go "Too Far" as you do with this kit, then you bottom out on the other end of the shock too soon.

Now, the problem with these Bilsteins, is that I am not sure how they were able to accomplish longer travel length while using a a shorter body? Well, I can tell you my first thought: The stock shocks have internal and external bump stops. These are mase by Monroe/Rancho for Hummer with these specs, required by Hummer. This basically shortens the travel of the shock and provides protection on both ends of travel range. What I am afraid of, is that Bilstein either did not know or chose not to include the bump stops!

This 2nd paragraph addresses Desert Dan's concern, if using the stock, Monroe or Rancho shocks. I am not sure on the Bilsteins yet - but stay tuned.

Please be patient - I will get some answers when the new shocks arrive

The problem seems to be "topping out" however I have run mine a year without problems with the stock shocks.

Mine is cranked 8 turns. Stock the bump stop is just touching the arm. Turned up you can get a finger in the gap. Not much travel. I did notice some nose dive with heavy braking. Maybe one of those shock type bump stops would do the trick.

Sweet, can't wait to get the skinny. There are other options, like the Fox H3 shock, but would like feed back on the cognito.

[tomp]

Hi Bebe,

I spoke to Cognito a while ago. Sounds like they left off the bump stops on the Bilsteins and they use the same length shock body etc as stock.

Probably not as cush in high impact situations when you might hit the frame-mount stops, but should provide better ride overall. Cognito claims very big improvement in ride quality over stock with cranked TBs.

If it's the same body length as stock and doesn't have the bump stops, they may improve stock height TB suspension setup as well. I know my H3 had some basket-balling ocurring even when stock, compared to my H2. Do note however, that the H2 has both internal and external stops on the shocks as well.

Anyhow, Bilsteins on their way....

Cool. I still think a slightly longer travel shock with the stops would be a better solution. Without the internal bump stop, whats to prevent it from pulling apart? I completely separated the rod on 2 shocks.

Also, the HD torsion bars would prevent the BB effect.

I guess we will find out :)

With a longer shock we shouldn't need the internal bump stop, as the upper control arm should hit the metal frame stop before the shock gets to an over-extended point where damage is of concern. However, then we have to worry about bottoming since the shock has no external stop - and rely soley on the soft frame stop.

If this turns out to be an issue, we could add the Daystar stops to our shocks http://www.daystarweb.com/ItemForm.aspx?item=KU09060&Category=ffb52a51-0a14-4505-8ee0-c22acc5e875b or replace the frame-stop with longer poly's: http://www.daystarweb.com/Categories2.aspx?Category=ffb52a51-0a14-4505-8ee0-c22acc5e875b

If I am not mistaken, you blew the 9000s? These have close to the same travel as stock and include the internal & external stops on the shocks. I really need to confirm this with Rancho, but this is how it is on the H2.

I really like the idea behind these Bilsteins without any other changes being done. It will be important when we get them installed to ensure the H3 front end height is in the shocks correct range. I will take some measurements and get it set up where it should be in the proper height range for them and I think we'll we good to go.

[Desert Dan]

I would rather have the frame bump stops due the work than the shock than the shocks.

[HummBebe]

I have all the stats on the 9000's, with both the internal and external measurements.

The 9000's shocks have almost 2 inches less travel than stock shocks. I have been running a pair of stock shocks up front for my last couple of offroad trips, and they are much better.

I have posted the measurements in one of my shock threads, I'll see if I can locate it.

What is iti that makes the Bilstiens different? Just the removal of the internal stops?

[HummBebe]

Aren't we limiting travel with the longer stops?

If you disconnected the front swaybar, would the negate the effect of the lower stop?

I'm working on some front quick discos now.

[Desert Dan]

Mo Travel is Mo Better

Get home from work last night and find long skinny box on the porch. Great, shocks for H3 came in. Can't wait to install them and try them out!

Get all the tools out and I get to work. Get shocks off and walk over to open box. Yikes, it's not even the freakin' shocks! It's trailing arms I sent out months ago to have new bushings installed. Fun was over...no test ride last night. Wasted effort....:twak:

When you do get them.....don't forget to take compressed and extended measurements as well as overall length before you install them.:D

[tomp]

Ok, I will try. However, I understand them to be high pressure charged and may be kind of difficult depending on the PSI they used:beerchug:

I just ordered a set tonight. We'll see how they do.

[tomp]

Ok, shocks arrived today. Wasn't sure where to take measurements from, so I took them from the tip of the threaded end and to the center of the bolt hole on the other end.

Didn't have time to install, but will get to that hopefully tomorrow...

The shocks measure 15.5" compressed and 21.75" uncompressed using the method above. Please let me know how this compares to stock and Rancho shocks. thanks!

If you look at the year make and model, both shocks have multiple applications. If they ask you what rear and model, defer to the part number.

PLEASE keep in mind Rancho will not warranty these shocks.....they are not being used in their "proper" application.

They will not warranty the H3 shocks either if your Torsion bars are turned, so... meh....

Looks similar. Glad they did it right!

Just a humble thought from the new guy.

When you compare shocks from different manufacturers you may want to measure from the top of the shock body instead of including the threaded stud in your measurement. The same shock, for the same car, form two different manufacturers may have a very different length threaded stud on the end. So in essence, when you measure, you are gettting the compressed/extended(travel) measurement plus whatever the difference is between the two studs.
I found this to be true when comparing the stock shocks to the Bilstiens. The threaded stud on the stock shock was longer.
I hope this helps

[HummBebe]

All of those measurements are on the shock specs link above.

And true, he should be measuring the body of the shock.

Hey Beebs, those links open the same pdf. Where are the specs?

[blindzebra]

I think I'll go with the Foxs when I replace mine.

[RuggedH2]

There is a lot to like about the Fox shocks (except the price).

I was thinking about Fox for the rear axle.

Okay, shocks are on and test drive completed. I drove it around for a while and what a huge difference! Big improvement over stock ride quality, even with TBs cranked!:jump:

[HummBebe]

I think, no wait I know that the Fox shock is FAR superior to any of these mentioned in this thread.

Yes they are pricey, but for the amount of money I have spent on shocks I could have bought a set of the Fox shocks.

The fox shocks are rebuildable. If you blow it, you can rebuild it for less than a replacement cost of the other shocks.

[Idaho-Hummer]

ok, I give up, where are you finding the Fox shocks at for our H3's?

[H3slate]

Fox shocks are available from Rod Hall Products. They are not listed on the website, but give them a call. When they are not racing they are very friendly and knowledgable.

HummBebe, have you purchased the fox shocks? I know they were recommended by a suspension guy working on HD torsion bars for the H3, just curious if you have had a chance to try the shocks.

[HummBebe]

No not yet, but soon. You can also get them from Sam at Samco Fab...

I actually am ready to oder the HD t-bars now. And when I get everything together, we will place the order.

The spring helpers I ordered are going on tomorrow. Can you believe I still don't have those on???

It's from Hellwig, and they are load pro 15's. http://www.hellwigproducts.com/products/helpersprings/loadproseries/default.asp They are progressive rate springs, so the more weight you add the firmer they get. No weight and you still have a comfortable ride.

You can get them at JC Whitney too.

Hey tomp, it's been a week .... do you still like the cognito's? I'm curious about body roll in turns, recovery after hard braking and shock response offroad.

[tomp]

Shocks are great. Definite big improvement over stock even with cranks TBs.

The body roll increase that occurs with cranking torsion bars partly occurs because you are no longer resting on the frame mounted bump stops. The shocks then assist with the body roll from there. I wouldn't necessarily say that these new shocks improve this situation any as I do not feel they are stiffer than the stock shocks.

High Pressure charged shocks really do not do a very good job at keeping body roll under control.

If after installing these shocks, you feel like it's still an issue (for me it's not) I would probably extend the bump stops to where they touch the control arm as they do from the factory. This should also assist with nose-dive when braking.

What about the HD torsion bars??? They should help with teh body roll?

[tomp]

not sure on that Bebe... would have to try it

However, I would think higher rate spring or TBs will place more demand on the shocks as the shock absorption rate of the shock will remain the same. This seems to me like it would worsen the body roll IMHO.

IMO, the best way to reduce body roll with cranked TBs would be stiffer sway bars and bushings, stiffer shocks and bump stops that touch the control arms like OEM. Keep in mind stiffer sway bars will reduce articulation. I wish someone would produce stiffer sway bars with quick disconnect links:popcorn:

Forgive my neeewbness, what are you supposed to do with the swaybar once you have disconnected it?

Are you going to Reno with the dealership?

I'm sure someone has thought of this, but has anyone checked with ProComp to see what they have that fits in the range of both untweeked T-bar and tweeked H3s..??

Just add info to it as more shocks are located or new ideas about modifying the suspension are discovered.

[Desert Dan]

Why do you think the travel would be different with tweeked Torsion bars?

If you raise the front end 1 inch with the torsion bars you get the same total ammount of travel up and down only your nuetral position is an inch lower so you have 1 inch less for the front wheel to drop (droop).

You really have to cycle the front and rear suspenion w/o a shock to see what limits the travel and then find a shock that fits.

With longer rear shackles you may be more travel and then you would need longer shocks.

Well the fawking enlighten us then please!!! I'm serious, I have done SOOOO much freakin research, stuff like that doesn't come up in tech write - ups.


Help me understand.:rant:

Please:fdance:

[tomp]

Unless you are planning on lowering the frame mounted bump stops, the new shocks will need to "not only droop further down due to the raised TBs - but to also be capable of going upward to hit the bump stop on the frame". If this is not the case with cranked TBs, you will be hard bottoming the shock and they will blow quickly. The newly required shocks for cranked TBs need to collapse to at least the length of the stock shock and provide longer length overall. This is exactly what the Bilsteins offer.

However, with either the stock shocks or the Ranchos, this should not be necessary as they come equipped with internal and external bump stops. The downside to these to offerings is the stops limit the travel.

Thanks for the info on the shocks Crash.

I am also checking with KYB (Gas Adjust) on what shocks they have for an H3.

They are gas charged with Nitrogen and seem to work well off road and on the highway on my past vehicles (Toyota Trucks).

Maybe Old Man Emu will make some for the H3 since its now selling in Australia?

OEM......... 15.0" 11.25" 3.75"
Edelbrock.. 15.67" 11.08" 4.6"
Fox.......... 16.0" 11.5" 4.5"
Cognito..... 18.42" 11.77" 6.65"
Rancho .....15.77" 13.43" 2.34"

I like the price of the Cognito's, and the extra travel, but would like to replace front and rear shocks so I leaning torwards Fox.

Isn't the rear shock just a standard shock, so I don't see why Bilstein would not have a factory replacement for the rear to match the front retrofits offered by Cognito.
