ran edlebrocks then switched to bilstein HD and the ride was awesome. Not quite like a caddy but way better than edlebrock or the stock shocks. I also ran the royal velvet shackles and had Michelin LTX M/S tires

It will ride a little stiffer. It does not bother me but my wife likes the car feel to it without the lift. She is a little picky. You can get 3 inches out of the lift keys but you should only go 2 inches to keep a good ride ( 2 inches will be with the bolts all the way out (down on the block). You can get them on ebay for around $60. They are not hard to put in with a couple of 5 ton pullers. Use two pullers to crank the new key into place and then take the one off that is in the way of the key block and put the block in. Do not put your fingers in the hole. If the puller gives you will have one less finger. Drive it around and if you dont like it put the old ones back in. If you like it go get the alignment. If you use spray paint to mark the bolts on the old keys before you take them out you can put them back in and not need to re-align it.

I am curious about the ride you get with the bilstein HD shocks. Did you do anything else or just change the shocks. I have a 2006 2500 HD crew cab normal bed diesel. The ride is normally fine but If I am on a toll road or something with shorter concrete sections it starts getting bouncy when I drive above 80( I know what the speed limit is thank you) I am wondering if the shocks would help that I had the same truck configuration in a 2005 model and it did the same thing

I am still using the same factory shocks but I plan on changing them out because they are a little maxed out. I am sure some day I will break them if I don't. My truck is the non HD model so you have a stiffer suspension to start with. Funny about the 80mph thing. Nice truck by the way.

The Bilsteins would help but you would still have that bounce over those expansion joints. It has more to do with the wheel base of the truck. The stock shocks do suck. I also replaced the shackles with velvet ride shackels and still had the bounce over expansion joints at 80.
I drove a GMC 4500 over some expansion joints last week. Talk about bounce with no load.....and I was going no where near 80.

My recently purchased Chev. Silverado 1500 ext cab two WD pickup rides rough. Unless the highway is very smooth you feel the bumps and roughness of the road more that I was expecting. The truck has the appearance of a four WD but is not. It sets higher above the frame than other Silverados I have noticed; even higher than some Z71's. It has torsion bars front suspension. On the rear it has a 2 1/4" block between the leaf springs and axle which causes the rear end to set up high. Was wondering if anyone has had the problem and if they discovered a fix for it. Also, do the torsion bars make the truck ride rougher? I thought all Silverado 1500 had coil springs at front suspension but I found out differently. Thanks for the input.

Was it used when you purchased it? It sounds like someone has placed torsion bar keys in the front end. It also sounds like they cranked them down all the way leaving little room for suspension. The stock keys have a nice ride but torsion bar keys will have a stiffer ride and a very rough ride when you crank them down. I think the truck should be 2 inches lower in the front than the rear unless they changed something in 06. You might be able to tell if you look at the cross member at the rear of the the torsion bars. Look in the middle between the gap and you will see there is a large thick metal piece. The stock should be a plain black and some aftermarket are silver. Some of the aftermarket are black also. The second thing to look at are the bolts. If they are cranked all the way up someone has cranked down on them to raise the front end. The bolts should be out at least an inch or so. Take it in to an alignment shop and have them drop them back down. You will need a realignment after this or you could just jack it up and do it your self.

This truck was new when purchased on 09/02/2006, had 42 miles on it. Therefore, I don't believe any alternations have been done on it since GMC made it. I looked under the truck, and although I am not sure I understand where to look for the large thick metal piece you mentioned at the cross member at the rear of the torsion bars (don't see one), there doesn't appear to be any modifications made. The bolts extend out 13/16" of thread, 1 1/16" counting head. To confirm your statement, the truck is approximate 2 1/2' lower in the front than the rear. Do you suppose the 2 1/4" block between the leaf springs and rear axle (I mentioned this in my original message) could be removed, which would lower the rear to approximately the same height as the front (it would appear to me)? Or would this effect the handling of the vehicle negatively? Thanks for your input.

Not sure on those rear blocks but I will bet someone will jump in with that information. The bolt you are looking at pushes up on the key between the rails of the cross member. The more you crank down on them the more front end lift you get. Some shops will crank them all the way down for you and only charge for the alignment. The truck will then be level. Problem is the truck will ride stiffer. The truck just might soften up on the ride after you put some miles on it. If not some new shocks might be the answer.

This is an answer to my own question asked in my reply dated 10/31/06 in which I asked if anyone knew if the 2 1/4" block between the leaf springs and rear axle could be removed, which would lower the rear end of the truck. This week I talked with the service manager of the dealer where I purchased this truck. He advised me would not be acceptable to remove this block; it would only cause additional problems (he did not say what kind). The conclusion I have reached concerning this truck is that I have purchased a heavy duty (this is my own description) Silverado 1500 ext. cab. two wheel drive that has a suspension like a four wheel drive (torsion bars, lift block on rear springs), that will haul a heavy load and pull a heavy trailer, a truck that is over rated for what my use of this truck is. And I did not realize this until I had purchased it, with little input from the salesman to design the purchase to my needs. Live and learn. One question I would appreciated someone's comments on is: what is the royal velvet shackles I have seen mentions in several e-mails I have read from this site and in what way do they help the rough ride. Thanks to all for your help.
