Front Leveling/Shocks & 35" Tire/Wheel FAQ
 

Okay well this is my second FAQ, let me know if you guys see any errors or would like to add anything!


What does the front leveling of the H3 do?

Hummer in their infinite wisdom decided to lower the ride height for their H3's so that the front end rides lower than the rear end. The leveling concept basically adjusts the front ride height to relate to the rear ride height (truck will sit square vs. being slanted forward), some people prefer the looks (looks more aggressive), and others will enjoy the many benefits of adjusting the front (greater ground clearance, larger wheel accommodation, better rear view, etc)

Why do I want to level the front of my H3?

If you run 35" tires, want to see out better out of your rear window, or want better clearance for offloading... you'd want to level your truck.

Do I need a "leveling kit"?

NO. The makers will make you believe that you require a leveling kit to level your H3. Basically, the kit is aTorsion Bar Key that will re-index the starting position of the Torsion Bar... the kit will essentially allow greater adjustments vs. the stock key. Keep in mind, the stock key has enough movement to allow you to level your Hummer.

One thing that the "leveling kit" comes with is shock extenders for your stock shocks. This will help reduce wear on your shocks and will allow your shocks not to over-extend them.

If you want to level your hummer without wanting to purchase shocks, then the leveling kit would be ideal, as you can use your existing shocks with your setup. Sometimes your stock key does not provide enough room for a complete level adjust, in this case, you will need to purchase a leveling kit key.

Who offers a "leveling kit"?

Truxxx
Readylift

What are the two differences between the two leveling kits?

Readylift:
+Cheaper
+Lifts ride
+Includes shock extension
+Solid construction one piece

Truxxx:
+More popular
-More expensive
+Lifts ride
+Includes shock extension
-Not one piece construction (welds)
-Can squeak
-Can damage the bolt due to the weld spots

Can I level my H3 without a "kit"?
[/b]
Yes. You can adjust your Torsion Bars without needing the expensive "kit". But keep in mind; you should not be over-extending your stock shocks. So yes, you don't need the kit to level, but then it's HIGHLY recommended that you purchase aftermarket shocks designed specifically for the leveling of the H3.

To make it straight forward: Buy a pair of leveling shocks = no kit needed. Keep OEM shocks = you may need extensions, or a spacer at the top.

What front leveling shocks are out there?

Edelbrock
Fox
Cognito
Rancho

What are the specs of the different types of leveling shocks?

Type, Extended Length, Compressed Length, 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"

Why are leveling shocks important?

[/b]Because they give you the extra length that is required instead of over-extending your OEM shocks and they give you the added performance boost. They also don't require little "extension" brackets to be added which can add another point of failure.

Do I need leveling shocks or a leveling kit?

I would highly recommend that you purchase shocks instead of a leveling kit. Why you ask? Well the kit comes with "extenders" for your OEM shocks, this allows for an extra part to fail and you are still stuck with the stock shock performance. Go with the shocks and you will not only have the extended lift that you need, but you have the added performance of an aftermarket shock.

What should my ride height be?

Your ride height MAX is 23.5"

RE: Front Leveling & 35" Tire FAQ
 

that sums it all up....except for two things....you can fit a 35" tire on a stock h3 without cranking the t-bars...been done before by a few people here with no problems...especially if aftermarket rims are used, stock rims may rub slighty on the control arms.

Also, with a t-bar crank or a front end lift kit you can fit a small 36" tire

Thanks import, updating that now.

RE: Front Leveling & 35" Tire FAQ
 

As a newB, I appreciate your write-up. Lot's of good info.

RE: Front Leveling & 35" Tire FAQ
 

Damn fine job.

RE: Front Leveling & 35" Tire FAQ
 

Updated this to include some more information and wheel information as I see the question being asked a lot.

RE: Front Leveling & 35" Tire FAQ
 

but what about 34" tires.....? :D:D:D


Seriously, a very good post and is appreciated by me for sure. I've got some 34's on the way with custom rims. I'll crank my Tbars a little, don't know that I'll go as far as 24.5" as mentioned above but I will at least get the front end a little higher than it is now and at least get it level left to right. I'm very surprised my H3 is about 1/2" off from left to right.


Thanks again for a great post, I've copied that info to put in my hummer vault.

RE: Front Leveling & 35" Tire FAQ
 

34's shouldbe a cakewalk :)

Quite honestly, going for the level look made a huge diff in how the car looks, I would go completley level :D Oh yes, mine was also a 1/2" off from the left to the right [&:] Beats me...

RE: Front Leveling & 35" Tire FAQ
 

Hey ockie, yea I'm thinking the 34's shouldn't be much of a problem. I've ordered 10" wide wheels, the Super Swampers are wide too. I'm sure as Mark (Gunner) mentioned to me before that the larger and wider wheels will stick out much further (about 2") and I shouldn't run into any inside rubbing on my control arms, etc. They look really mean with those big feet sticking out... The one downside is that it'll be hard to keep the H3 clean with that large of tire on it. I've got GM mudflaps but they don't stop road spray even with my stock 265s much less these honking 34s going on it. That's OK though, I'd rather have the big tires and all that goes with it including the extra dirt it's surely gonna sling.

I like those aftermarket fender flares, they really look nice but I don't think they're wide enough to help much. I've only seen photos of them and they look like they may extend an inch or so beyond the stock fenders.

I'm glad you posted some shock info too, I was considering an extender block for my stock shocks but I don't like the idea of having one more potential point of failure. I'll probably look into some longer aftermarket shocks. You posted several options and each was a different length. Just looking at the numbers the Fox seems like the right range for me, however the Cognito's have much more overall travel and fully extended range. Not sure if I can take advantage of that with the 34's but I'm thinking that going to a longer shock is the smart thing to do.

Are there any thoughts on changing all four shocks with the same brand as opposed to only changing the front shocks? I know I'm only changing the height up front but I wonder if that effects the rear suspension too, seems like it will add more load to the rear and if that's the case is it prudent to put a better shock set on the rear as well, not necessarily a longer shock, I'm thinking more of a "better" shock with better damping and more strength. Thanks again for the info, this kind of stuff is what makes this forum a must read for Hummer owners.

RE: Front Leveling & 35" Tire FAQ
 

I haven't noticed negative effects with keeping the rear shocks stock, but it drives me nuts knowing that my front end is all good and my rear end is stock. I have been thinking of getting matching rear shocks so I can have the same on all four corners... I also want something thats going to perform a little better, especially in worse conditions.

As for the flares on the sides, I don't see either how they can make such a huge diff, I just decided to live with the dirty car effect... besides, it's a HUMMER :D

RE: Front Leveling & 35" Tire FAQ
 

I installed the ReadyLift leveling kit on my a couple of weeks ago with 305/50/20 (33's). 35's would be no problem. I have experieced no problems at all. Just make sure you have it alingned to the specs with the kit. After installing the left tire rubbed on the sway bar, but after the proper alignment, that went away.

There absolutley no affect on the ride whatsoever. infact I will be changing my shocks because it's just too soft for me.

The best thing about the the lift is it's cheap, easy to install, and a great way to improve the looks of the car. Takes the wedge look out of place. I get tons of compliments on my ride. They always ask if I lifted the entire car.

Do it.

RE: Front Leveling & 35" Tire FAQ
 

I hate to sound like that kid in class that "just can't get it", but how do I know which shock to buy from Rancho or Bilstein?
I just did the torsion bar adjustment and have noticed no problems for 200 miles on road driving, however, I am having my dealer check everything and make sure that it is ok tomorrow. He says that I should be fine but will check for me anyway.

RE: Front Leveling & 35" Tire FAQ
 

Search "shocks", I believe you will find that the consensus of the forum is that Ranchos are not as good as they used to be, andtherehasn't been any complaints as to the bilstein cognitos?? There are a couple other brands to consider as well.

RE: Front Leveling & 35" Tire FAQ
 

im new to this whole site and that was alot of great information on leveling.... im 15 years old and im getting a 2006 h3 lux package. i was wondering if i put the truxxx leveling kit with a 35 inch toyo open counrtry and a 20 kmc rockstar will i still get the same agressive look as the h3 adventure package with the same set up?

RE: Front Leveling & 35" Tire FAQ
 

I recomend that you do not go with the truxx leveling kit, just go with the better shocks and do it right from the start. You will get a more aggressive look.

You should consider the adventure package if you are interested in doing some offroading.

RE: Front Leveling & 35" Tire FAQ
 

thanks ockie, go with shocks.... what do you mean by that? and i dont know if im getting the adventure package or the lux package ... it will be a birthday gift from my dad, so he is picking it out.... can you maybe send me a link for shocks or just explain to me what you mean. thanks alot man... your a big help!

RE: Front Leveling & 35" Tire FAQ
 

ockie thanks alot for the info... the thing is, im turning 16 may first that mean i would get my learners permit ( i live in new york ) and i would work all summer to spend the money to hook up my h3, i dont know if my dad got me the adventure kit or the lux kit, its a surprise, you said shocks instead of the kit... can you show me a website that sells the shocks? and my price range would be anywherefrom 1,000 to 3,500 maxxxx. thanks alot man.

Has anyone heard how the Sandy River Enterprise 3" lift w/ rear add a leafs or w/ rear lift shackles? Are they causing any problems?

RE: Front Leveling & 35" Tire FAQ
 

I'm just going off of the 3 H3's that I have done, they seem to start out around 22 1/4 - 22 1/2". The rear of the truck is at 24", make sure that youmeasure from the center of the hub to the bottom of the fender.

Has anybody ever used or heard of the leveling torsion key lift that skyjacker makes for the H3?

RE: Front Leveling/Shocks & 35" Tire/Wheel FAQ
 

You don't need a key lift, all the key does is reposition your tbar starting adjustment value. The stock should give you more lift than you will ever need.

RE: Front Leveling & 35" Tire FAQ
 

Hello all.....i have put on the cognito/blistien front leveling shocks on and the ride is far better than what i was attaining from the factory shocks....if someone is looking at leveling out the front end...i would suggest putting the shocks first then doing a level from the torsion....what i found out is after you have done a torsion bar twist in increase the level of the front end and have not put on the shocks prior , you will have to to another series of torsion bar adjustments after you put the new shocks on....why?.....i havnt a clue but the i did the torsion first...leveled out the ride....noticed a decrease in shock travel then installed new shocks...my ride was cockeyed and had to re do the torsion twist as i like to call it.
the H3 FRONT LEVELING SHOCKS by Cognito are excellent....i highly recommend them but do the shocks first then the torsion bar

All the best..

RE: Front Leveling & 35" Tire FAQ
 

The correct front Bilstein shock number if doing a Torsion lift is F4-BE5-C153-HO. The proper rear Bilstein part number is F4-B46-1698-HO for stock height rear ends. Hope this helps.

RE: Front Leveling/Shocks & 35" Tire/Wheel FAQ
 

I just leveled my truck with the skyjacker leveling kit and the mechanicrecomended new shocks because the oem ones were extended due to the kit. Everytime I hit a bump the truck bounces. What shock's should I buy and will they actualy help?

RE: Front Leveling/Shocks & 35
 

i decide to put 35" tires on my H3 but i have some doubts now on what to use !! i was gonna get Cognito Bilstein Hummer H3 Leveling Front Shocks!!! and besides that do i need anything else bump stops,lift kit,leveling kit any thing ?? I just found these they look gd quality any feedback and do i need to get leveling kit? http://www.trailduty.com/product_inf...roducts_id=778

Can we get some samples of before and after pics?

hey guys
i got a 2.5' leveling kit and longer bilstien shocks (5100 series) and i want to fit 35" tires, what r best rims to avoid rubbing and retain my steering

How does the I5 perform after putting on 35's?

Thank you. This is the first thing I will do.

I fitted the Ready lift 2.25 levelling kit with ARB Old Man Emu Shocks all round to my 09 H3T. All works great, I use 285/75R16 BFG's most of the year, in winter I put on some 305/70/R16 MT & it's clear their is plenty of room for more rubber - I'm sure 35's will look great

I curious to know.... Do you use the leveling shocks in addition to torsion adjustments, or in place of doing the torsion adjustments?

Also, how long are the factory shackles for an 08 H3? and if adding aftermarket shackles, what are the length on them?

Please do some searches on leveling the H3, there are 4 bazillion posts on it. Same thing with rear leaf shackles, but not as many threads.

You do NOT need new shocks to level the front, but you can add them if you choose, as well as extended bump stops. Best option is to adjust the front to where you want if (Max= 23.5" fender lip to hub center), get an alignment, then decide if you want different shocks, shackles, bump stops.....

Thanks Doc Olds. I do want to level the H3 out and optimize the performace of the suspension without sacrificing handling and ride comfort. I have looked at several post, just was not clear on if the shocks would do the lifting or if I had to turn the keys on the torsion bars. I read on a post here that the best way to do the leveling was to just get some leveling shocks and not waste the money on those kits that sold the keys and required extensions therefore comprimising the handling of the suspension.

Shocks do NOT provide lift, they only dampen the suspension movement. You turn the OEM T Bar bolts (adjust them) for lift, as little or as much as you want up to the max of 23.5".

Leveling kits are a useless waste of $$, you got that correct.
