Default Suspension Discussion

Ok, I thought with all the front end upgrade posts that maybe its time to have a suspension discussion.

Here is my question - has anyone gone with a coil-over suspension setup for the front end yet? I know these setups are pricey as hell and I'm not even sure if they make them for the Deuce, but I have been pretty disappointed with my front end for a while now.

My problem - I went with the skyjacker lift, I think it gives me 5-1/2" lift. Rolling 40's, cranked the stock keys all the way up and added 1-1/2" spacers on the back under the coils to even out the stance. Looks ok, except for when I turn into a dip, the tire digs into the frame big time and makes a huge pop from it hitting the frame on the back of the wheel well. Also, when I hit a dip in the road, the truck bounces up and down and there is a huge pop from my wheel shooting down after absorbing the bump when going slow over a dip - pretty sure it is from the keys being cranked and the wheel is shooting back down under the pressure.

Now, I know I need a new steering setup simply because of the 40's eventually. I was thinking of getting the green keys that everyone talks about, but I'm not sure if they are going to give me enough of a change to notice. Rocking Bilstein shocks too, so good to go there. I guess the point I am trying to make is that I would like my truck to just be able to hit a bump and absorb it nicely without popping, rubbing, or bouncing. About ready to take it to a body shop and have them cut out part of my wheel wells just to open it up, but I know that this isn't going to get me to where I can hit something and have the suspension suck it up like a desert buggy. Whatever I decide to do next will be drastic, so I want to see if thereis anything I am missing before I go chop shop on my truck.

Pretty sure there are others out there too that are maxing out the 5-1/2" to 6" lifts with 40's and are wondering the same thing, so let's talk about it.

If your getting bounce- then your shocks are junk. If they are new then they are to small to dampen/resist the movement. Your going to run through components 4x the rate of stock w/ those monster wheels.

You still have your stock wheels/tires or access to someone that can loan you a set? If so I'd put the stockers on and back the t-bars way off, take it out for a spin see how it handles. I've not heard one person ever say they were happy w/ the handling after cranking those bars. If you then get some ride quality back, that should answer your question about the green keys.

Throw a 2" body lift on it...probably solve most of your clearance problems. There is a 3 page thread on body lifts here about 4 months back. Should have all the info you need.

The only way I'd ever put 40s on an H2 is if I installed a solid axle up front and push things forward enough to allow for plenty of tire clearance. I'd also address the steering woes with a hydro-assist and drag link. Otherwise you are going to have to lift the vehicle up too much to get the needed clearance and still have concerns with steering, half shafts and front diff being strong enough. Sure, there are others whom have managed to get 40s on theirs but have to live with some issues and never really gain much in overall functionality. Just my two cents...

Great input. I agree that I need to upgrade the sterring system, just have been putting it off. I am just a little bit sad that there was not a little more effort out there on people making stuff for these trucks. I just can't see my ride on anything smaller than a 40", but then again that is the "going big" syndrome there talking as once you upgrade adn go bigger, you just keep wanting bigger, you never want to stop.

If only there was such a thing as a 7" or 8" lift, that would be perfect. Maybe I will see about getting some custom stuff made to try and work it out without digging myself into a financial hole. I will be heading to SEMA this year, so I will see if there is anyone out there that can help me out with this situation.

If you owned your rig in 2005-2009 there was so much hummer aftermarket parts on the market, it was crazy. New vehicle being sold, tons of suppliers were cashing in on owners blowing alot of cash on customizations. There was a lot of really cheaply made parts being sold for stupid prices. 2009-2010 everyone was whoring out the remaining inventory on ebay. Whats on there now is basically the crap no one else ever bought. There are a few good things here and there, nothing close to back then.

7-8" lift is easy.... 6" fabtech + 2" body lift.

Front end bounce can also be contributed to worn steering parts, where toe in and out will magnify any bouncing that would normally level out quickly. Typically this is pitman and idler arms but worn tie rods can also contribute
