Do the TSB leaf springs settle?

Hey guys I know it's been posted a bunch in a bunch of places, but I want to get your opinion on my situation. I just got 5100s installed all around and at the same time swapped out my non tsb leafs for some 2008 tsb leafs, on my 2006 dc.

I thought setting the fronts at 1.75" would level it out with the rear tsb but it still sits about an inch and a half higher in the rear... Will this settle or should I consider bumping the fronts up to 2.5"???

 

Yes , TSB leafs settle

 

Even though they're used tsbs from a different truck? And how much do they usually settle?

 

Hard to know how much they have or have not already settled

My truck came with the " TSB " 4 leaf pack stock , I lost 1 1/2 - 2" of height over 6 months of hauling about 300lbs daily

 

wow they settled even though the 300lbs was in the drivers seat?

 

Lol

 

Haha cool. Thank you!

 

For reference the hub to fender measurements on my 2007 tsb pack with 200000km are 22 inches on each side
