Got new factory leafs installed after a recall, but they're still crappy leafs

They've only been on for a few months, but they're already going slightly frown face.

Are they worth keeping and adding a leaf (like Dakar)?

 

I'm just gonna rock mine until they're done for and then get a whole new Dakar pack. I've only had mine for 2 months and they're flat as a pancake, almost on the frowny face side. I do load my truck pretty heavy with oak every now and again, but only for a 15 min ride, so I don't know how much that's affected it.

 

Why does Toyota cheap out on their suspensions? Their rear leafs have been dog shit since the 1980's.

 

Yea, my TSB springs were a disappointment for sure. I cut a pair of springs down from my original stock leaf pack and added it to the TSB's for a 4 + overload. It was a free add-a-leaf that only cost me the price of a new pair of center pin's and I picked up at least an inch of lift and actually have a smiley curve to the rear leafs. I figure that as the TSB sag more I can add the other original factory spring. Disclaimer: I have a Leer shell and carry I'm sure 150#-200# of tools all the time.
