    Default Torsion bars? Want to lower the ft. of my truck

    Not sure if this pic is any help. The truck I bought a bit ago is a 2001 3/4 ton gmc...2wd. A previous ownder has lifted it. Who ever did must have been smoking crack because the front end is about 3 inches higer than the back. Any one have a clue if I can lower the front end on this...preferably for free. lol

    Also...if it can be lowered....how much do you think I can lower it before I start causeing a caster/camber issue?

    jus spray paint the torsion bar adjuster nut assemblly really good, and back them both off a turn at a time evenly , back the truck up and back a couple times to let the arm's unload alil and check it, may have to do that couple times to get what ya want. jus make sure you either bounce or drive it alil in between so the truck settles and ya know what ya got then go get it aligned

    Dare to be different, if it turns out great you can claim you planned it that way.

    At the risk of looking as clueless as I really am here....is this the adjustment? If so....does this look to be cranked most all the way up....or down.

    These trucks often lean to the driverside. The fuel tank is on the driverside as is the driver. To get an even left to right stance sometimes requires what appears to be an uneven adjustment on the keys. The torsion key adjuster bolt with no threads showing is maxed out as far as lift goes. If you aren't sure which way to turn the bolt you probably shouldn't be under the truck working on it --- lowering the front height by backing the keys off a little should noticeably improve the ride quality too. I wouldn't worry about having issues correcting the camber / caster once you reduce the ride height, a quick alignment should get you back within factory spec.

    righty tighty lefty loosey applies here too backing out the bolt removes tension from the torsion bars, which lowers the truck.
    as mentioned, you'll notice a huge improvement on ride quality as you back them off, i hate when peeps crank them down, beats the hell outta ya in the truck

    I will try to take some better measures before I start. Just using an eyeball and a tape measure it looks 1/2" or so higher on the drivers side. I figured that was a dumb question....but I would rather ask than strip a bolt. I gave it a tug both directions...and it didn't want to move either way. I haven't got to carried away yet...because I don't have a spare 80 bucks this week for an alignment. I will try to post some before and after shots. It drives me nuts to see a truck sit higher in the front than in the rear....let alone to own one.lol

    This particular part of the GM suspension likes to rust. A liberal spraying of your favorite penetrating oil on everything the night before will help prevent a stripped adjuster bolt. This adjustment procedure needs to be done with the front wheels up in the air and the frame supported by a jack stand. Trying to adjust the torsion keys with the full vehicle weight on the suspension is NOT recommended. With the front end in the air, and a few hours of soak time, this should be an easy project. Normally the amount of camber change is minimal... the front might toe out a little as the ride height is reduced but this shouldn't present a major issue for a weekends worth of driving. If it wanders real bad during the first test drive you can increase the toe in a little to get it close until you can have it professionally aligned.

    driver's side? those trucks wear out the lh frame mount all the time, been doin alot of those mounts that are riveted to the frame. we charge 2 hrs for changing both, and i've got it down to 30-35minutes total now

    Yep! Drivers side. I never noticed, Custom Truck Shop found it while fixing my train horn. They repaired it and beefed up the other side (just in case) for $100.
