Hey Gurus....

 

My torsion bars have been up and down so many times its not funny lol. Anyhow, Ive got them all the way up now and would like to lower them some. Is there anywhere that I can find out where they are set at from the factory?

Not really.  I'd say pick a height and match it side to side.

I think the best is to measure the height of the vehicle from the bottom body panel on the front doors...otherwise with the wear on the tbars, you can't measure at how far that bolt is threaded.

 

I don't know the stock height off the top of my head, but I did find something a few months ago that listed this measurement.

Agreed with that, after the years of wear the factory settings wouldnt mean much now, especially after hauling a plow around.


Was there really a factory setting as some trucks seemed to have some rake, others were more leveled?

I've found that when adding anything to the front like a plow or winch the torson bars need to be the next higher load rating that being said if you have a 3500 w/highest rated bars then fat bump stops help or after market bars.
