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

[tomp]

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....

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

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

You will see a line at the bottom Measure from there.

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

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!

Here is the Rancho Specs....

2006 Hummer H3
Front shock IFS
Compressed length 13.43 Extended length 15.77
2.34 Travel


Rear Shock S
Compressed Length 15.25 Extended length 23.49
8.25 Travel

Now for the Avalanche 4" lift for front replacement:

Front shock IFS
Compressed length 13.875" Extended length 20.75"
6.875 Travel

Rear Shock Suburban 4" lift shock
Compressed Length 15.875" Extended length 26.25"
10.375" Travel

Link to Shock Specs
http://www.gorancho.com/flash/docs/2005_shocks.pdf

Part numbers: Rancho 5000 Front RS5268
Rancho 9000 Front RS99268

Part Numbers: Rancho 5000 Rear RS5190
Rancho 9000 Rear RS99190

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....

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
