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.

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 06-04-2007 06:45 PM

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

They are to the right of the shocks. I was also disappointed with how some of their accessories disappeared when they changed names.

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?

Just let it hang there. :giggling:

Are they going to Reno again? I haven't heard anything, but would love to go. I had a blast down there. I want to go explore Peavine some more. :dancingbanana:

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..??

What range do I need to be looking at anyway..?? (That's NEED not what is stock)

Kinda fill in the blanks..
Front No T-bar adjust Compressed _____ +/- ____
Front No T-bar adjust Extended _____ +/- ____
Front T-bar tweeked Compressed _____ +/- ____
Front T-bar tweeked Extended _____ +/- ____
Rear Stock Compressed _____ +/- ____
Rear Stock Extended _____ +/- ____
Rear Shackled and Disco'd Compressed _____ +/- ____
Rear Shackled and Disco'd Extended _____ +/- ____
(Bebes knows where I'm going on those last two):shhh:

What shocks are known to work right in these situations..?? Manufacturers' and part numbers would be nice.. I'm thinking if we could get all this info compiled it'd make for a good sticky thread or FAQ.. Just add info to it as more shocks are located or new ideas about modifying the suspension are discovered.

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

Re: New Bilstein / Cognito Hummer H3 Leveling Front Shocks???
 
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.

So what are the specs on the Bilsteins..?? Full Compression... Fully Extended... The Ranchos..???

Found these ProComps that MIGHT work on the front..

The KMX086 is listed for the H3 but it's specs are kinda short.. 15.5 - 11.02

The these are listed as generic shocks rather than for an application, but the specs are dang close to the Bilsteins, maybe better..

There's a TON of Monroe shocks that fall in close to these specs too.. But they have quite a few different end mounts.. If it's worth anyone elses time..

Here's the list with dimensions

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?

Re: New Bilstein / Cognito Hummer H3 Leveling Front Shocks???
 
So for those of you who have not kept up on the shock threads, there are few makers who actually make a shock for the H3

ProComp
Rancho (they suck hard)
Cognito/Bilstein
Fox
Edelbrock - maybe...

That's it.

Anybody have the part # for the fox shocks? It would be nice to compare specs of their racing shocks vs. the cognito/bilstein.

No KYB shocks yet per KYB

I haven't found any info on OME and ARB

Are the Bilsteins gas charged?

They may have something that is the right length, but the problem is the mounting. The B/C are actually standard Bilsteins that Cognito modifies to fit the H3.

Thank you my Queen!

Shock extended collapsed travel

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.
