Torsion Bars

[Cruiser2500HD]

Hello All,

 

I have a 2002 Silverado 2500HD.  I've seen in a couple of places that people talk about "cranking" the torsion bars.  Two questions:

 

1.  Is this the adjustment under the truck to level it under heavy load?

 

2.  Does cranking it effectively raise the entire truck or just the rear?  I haven't messed with it yet.

 

Thanks for the help guys!

 

Just for the record, and if anyone is keeping track....

 

I have the 2500HD X Cab, short box 4X4 w/ the 6.0L engine, auto, towing package, snow plow prep package, locking rear diff, and 4.10 gears.  I just recently towed a big load (by my standards anyway): a 1990 Toyota Land Cruiser packed with stuff on a big trailer (the L.C. is about 5K lbs, trailer about 2K lbs, and probably about 1K lbs of stuff inside the L.C. so 7K to 8K lbs total).  Towed through the southern tier of Western New York (lots of hills) and have no complaints at all.  Engine and transmission did a great job with this load.  With my usual smaller loads (about 5K to 6K lbs) this truck pulls with no problems at all.  At about 13K miles now and the truck has been great.... only two small issues with it:

 

-the infamous valve noise / piston slap at start up

 

-windsheild moulding naise at highway speeds after the installation of a bug deflector

Hello All,

 

 

1.  Is this the adjustment under the truck to level it under heavy load?

 

2.  Does cranking it effectively raise the entire truck or just the rear?  I haven't messed with it yet.

1.  The adjustment is under the truck, one for each side.

 

2.  The Torsion bars raise and lower the front of the truck, not the rear.

 

I have not touched my torsion bars on my 02 2500HD, but I have heard others say it makes the truck ride stiffer.  I have made this adjustment on an 88 1500.  It seemed to shorten the up travel of the sup.

 

Most people raise the front end so the truck sits level.  I pull a 5er and when the trailer is hooked up to the truck it is pretty close to being level, so I'm leaving mine alone.

I have mine cranked level w/the back.  There are MANY posts about this in the LD forums.  Try a search w/keyword "torsions".

Riases the front.... now that is interesting.... for some reason I thought it was meant to raise the back under very heavy loads..... thanks for the information!  I'll check out the links....
