Rear leaf spring options

I have the tsb rear leafs now and they no longer curved. About 100,000 miles on them. I don't want to waste money on an AAL and have the same problem next year. I'm looking to replace my spacers up front with new shocks and springs later this year. I like the Darkars, but probably only want 1.5-2 inches of lift in the back. I'm 90% On road with the truck and probably have 5-10 heavy loads a year. Any suggestions.

 

IIRC.... You can remove the third leaf from the top. Will yield 2"

 

interested in same thing dont want to lift but want to increase capacity of rear, mine is 2016 and after last 2 trips to moab with full load definatly rear needs bigger leafs but not full blow 3 inch lift with darkars.

 

Airbags

 

Possibly add the Icon add a leaf pack, says it's 1.5" lift in the rear but I haven't tried it myself yet...

 

Dakars and you can remove the 3rd leaf and top overload for closer to 2inch lift (apparently this is what ARB/OME suggest)

Wheelers also has their version of springs for around a 2 inch lift.
