'99 Nbs Silverado Z71 Front End Sag After Torsion Bars Cranked

[famouslee99gt]

Not long after I got my truck (3 1/2 yrs ago), I decided to put a snowplow on it. So I cranked up my torsion bars. When I went to do that, the driver side one had already been cranked up some, and it wasn't the same as the passenger side. Whether that was to accommodate a larger individual and gas tank prior to my ownership, I'm not sure. Anyways, I have used Timbrens in the front of my truck to help offset the weight of the plow and I don't keep the plow on the truck anymore than I need to.

 

Now I'm starting to notice the front end seems to look like it sags. When I first cranked the bars up, the truck looked like it set level. Now it doesn't. I did install coil-over shocks in the rear which raised it slightly, but it still seems the front is sagging. The truck has almost 131,000 miles on it. Is it possible that my torsion bars are getting weak?

No...but they may be taking a set (allowing it to sag). They have the same spring rate as before. They may have just twisted a bit and taken a slight set.
