Should I consider new leaf springs soon?

My truck is a 2017 off road model. It has about 52,000 miles and the leaf springs look flat. I have a 200lb topper that's been on it for about a year now. Other than that the bed it empty for the majority of the time. The truck still handles fine, and I don't feel like it needs new suspension right away, but if it's time for the leaf's to be replaced, I might as well do the whole thing. Just wondering if an add a leaf would be a good solution or should I get new leaf springs.

 

Flat is the normal look for stock leaf springs on any Tacoma, if you get lift springs then they will be more U-shaped

When they start to look more like a W or frown shape then its time for new ones

 

Same as above, mine looked flat from factory with zero weight added

 

thank you!

 

Leaf springs are not a wear item. Flat is normal.
