Chevy Silverado and GMC Sierra Suspension and Ride



  • I have an '07 1500 Z71 crew cab Silverado (new body style). I love the truck and the smooth ride but I hate the low front end look. I want the truck to look more "beefy" but keep that smooth ride and without getting a whole suspension lift, I heard their too stiff. I've been looking at leveling kits and was wondering if anyone had suggestions which are the most durable but keep that smooth stock ride. SOMEONE HELP! I see alot of '07's around town and I want to stand out "above" the crowd. THANKS!
  • I was very surprised when the right rear spring shackle broke from corrosion. Granted I live in New Hampshire but (7) years and (50,000) miles to have thick steel stamping rust completely through is un-believable. It's obvious the steel is below the basic low-carbon junk variety.

    Has anyone on the forum had the same problem?

    I have had good luck and performance from this 4wd, 2K, Sierra - but I could not justify purchasing another GM product knowing their poor quality on these safety issues.
  • Just put a level kit in the front of 2004 2500HD Siverado. Lots of noise like thumping and rattling comming from the front now. Ride is not so bad. The bumper on the low a-arm is about 2 3/4 inches away from arm. From factory it touches the arm. Had it re-alinged. Drives fine just lots of noise. Anyone have this problem when they leveled their rig?

    Sounds like a bad install or a defective kit. There shouldn't be any thumping or rattling from installing a leveling kit.
  • Your right and I found out today what the problem was. While working on rattles and sqeeks I decided the shock was the problem. I took it back to the shop were the levling kit was installed and they put it on the hoist and found out they hadn't tightened the lower shock bolt. Voila it is whisper quiet and rides very good. I'm aware of the a-arm issues. Time will tell I guess. Thanks for your reply.
  • i was woundering if lifting your torsionbars will hurt the ride of your truck

    That's a big 10-4.
  • Hey everyone, I've been thinking of leveling the front end of my truck. Has anyone done it on a new body style silverado Z71 4x4? Did you crank the torsion bars or use a leveling kit? Thanks
  • You do have the heavy duty 1500. Also, the reason for the back to be higher is gas milage and no you should not remove the blocks as this could change your drive shaft angle which could cause vibration under hard acceleration. And as far as torking down your torsion bars, thi will not stiffen the ride much at all but if you go to high, the upper control arms will hit the bumstops. good luck

    I have an 03 Crewcab 1500HD 4x4 which when purchased had the tortion bars cranked up to level the truck out and to accomedate 295x75x16" tires, rides rough. I was told that Off Road Unlimited sells a leveling kit that replaces the armature that the tortion bar fit in. It changes the pitch so that you can have the hight but gives you back the travel so that it smoothes out the ride. Is this so, does this work or are they just trying to make a sale.
  • I have an 04 solverado w/ 80k miles.
    I am getting a hum/vibration above 30 mph when I turn to the right. I believe the left front bearing is about to fail.
    How do I know it is the left or right side and how tough a job is it? Are special tools that GM is so famous fro required?

    My 06 silverado 1500 w/ 35k also makes a noise and vibration when turning to the right at speed between 35 and 55 mph. I have not heard the noise when turn left or at low speeds. I also experimented in both 2 and 4 wheel drive, but could not hear a difference in the noise. I finally got the dealer to hear the same noise on a test drive today and will let you know what they find once I get the car back. I did have the right front wheel bearing go out on me at 27k, but fortunately it was repaired under warranty.

    My dealer confirmed that the noise when turning right was the left front wheel hub assembly bearing.
  • thanks for the response.

    I talked to the dealer and they said right off the bat it was the bearing.

    They said the part was $408 new and about $300 after market.

    $95 for labor.

    I am looking online for the part and I will do it myself.
  • Are there suspension systems out there where I can lower my Truck for the street nights....and raise it up a bit for the off-road days?......all in one package.
  • I own a 1997 Chev. Step-side 4x4, 5.7L, where can I pickup a good functional Ram- air hood? Will it direct air into my stock breather housing? Can I use this hood on rainy or snowy truck is a 365 day/year ....not a yard ornament.
  • I have a 00 Sierra 1500 ext cab. I am thinking to put a 3in body lift, add a leaf, and torsion keys. I would like to know if i would need aftermarket shocks and if so what would you recomend?

  • what is better...... i have a 1988 1500 sierra long box, and want to put a camper on it, the camper is older and weighs about 800 lbs, our vehicle weighs about 6000 lbs. we do not know what the gvwr for our truck is, as it was removed from the door, if someone else has a truck like ours, could you let us know what it is...we want to know if we should put 1 or 2 leaves as we already have 4 on each side, or should we go with the air bags?
