I just took my truck in to my dealer to get the torsion bars tightened to level out the truck He told me that on the 1999 to 2002 gm trucks it would not make a difference. Is this true? I tried to convince him that it would make a difference,  I even told him I would bet him a case of beer and he said he didn't want to argue with me. Can some one help me out with this. Will tightening them make a difference?

2WD or 4WD?

 

If the truck is 4WD then teh answer would be yes, you can in fact get some lift in the front end.

 

If the truck is 2WD then I don't know.  I don't know if a 2WD 1500HD would have tortion bars or coil springs in the front.

 

I took about 3/4's of an inch of "droop" out of the left front on my 2500HD crewcab by tightening the bolt on that bar.

My truck is 4 wheel drive. Now the dealer tells me that they don't want to do it because it will put all my front end specs out. I'm undecided on what to do. Do you need a wheel allignment after you get the bars tightened?

I sure would like to level out my truck. My service guy acted like I was the first person to ever tell him that they wanted to level out their truck. Any advise would be great...

 

 

Shotgun, your truck looks great level.

Sounds like your dealer is a little anal. :) My dealer offered to do it when I took delivery,but I wanted to reasearch before I did it.I would get an alignment done after doing it just to be safe.I haven't had mine checked yet and I can tell you that I don't think it's out at all.I marked the head of the bolt and the crossmember to make sure I turned each side exactly the same amount.I don't regret doing it at all.Hope this helps..Gun

If you have to turn the bolts more than 3-4 turns it would be a wise idea to have the alignment checked.  It may still be OK if it was set at the bottom limit of the specs at the factory, but if it was at the top end of the specs then you will most certainly take it out of spec by tightening the tortion bars.

 

GM won't pay for an alignment check on your vehicle unless it has 3000 miles on it.  Your dealer may be reluctant to do it at all if he knows you cranked your bars.  Talk to him first and see what he says.

I cranked mine 8 turns to level off truck,It raised the front almost 3 inches......Gun

 

I see some people saying that they get an 1-2 inches out of 8 cranks and others get up to 3. 3" is good, pretty much a free lift :)

 

Shotgun: Your 305s fit under there with no problem rubbing?

No rubbing and the dealer told me that the bolts on the 1500HD's are really not torqued much,not as much as the 2500HD.......Gun

Turned mine 4.5 turns and raised the front 1.5 inches.  I took it to the local alignment shop to have the alignment done.  I did this incase something goes wrong and a key happens to break or something else goes wrong.  That way I turn the bolts back to the stock setting and return it to the dealer to be covered under warranty.  I'm sure adjusting the torsion bolts wouldn't void the warranty or anything, I just wanted to be safe that sorry.  The ride did stiffen a little with the adjustment but hey....  It’s a truck.

Just thought i'd add my two sense.  I have an GMC 01 2500HD and I cranked mine up to level with 285 BFG MT...Got about 3 inches or so.  I have done this on my last five chevy's.  If you fool with the front end at all...you gotta get it realligned cause it'll not only lift up but will also affect your camber...  If you just dropped 900 bucks on tires you'll be pissed when the sides are rounded.  Turn em up yourself, just keep it even, they put your tires on and have them align them for ya.   Be careful not to crank them up all the way or you'll not only be in for a hella rough ride but you'll risk breaking something if you doing any significant wheeling.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because it’s in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      Gas Prices

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
