Want to refresh suspension on lifted truck - help identify what I have

I have a 2011 TRD Off road 4x4 crew cab. It's a great truck and I like it just the way it is. The suspension is in need of a refresh, but I'm not sure what is on there now. I bought the truck 3 years ago with the suspension and rims already installed. The only thing I've done is replace the tires (with the same size that was on there) and add the rock sliders.

It turns out I only do mild offroading (ended up getting a dirt bike). I have some extra weight from rock sliders and and a front ARB bumper. Tires are 285/70r17 (slightly smaller than 33s). No tire rubbing, even when I took it offroading.

Can anyone help me identify how much of a lift I have on there? As seen in the photos, rear measures 38.5 from the ground, front measures 38.25 from the ground.

I'm thinking of replacing the worn out shocks with factory take offs or Bilstein 5100s. Would that work? The coils seem fine so I would likely reuse those. Not sure how to tell how much life the rear leaf springs have left in them. Any advice appreciated!

 

Updating my thread, it looks like most people measure center of hub to fender. So I did that and found:

Front center of hub to fender driver: approx 22.5"
Front center of hub to fender passenger: approx 23"

Rear center of hub to fender driver: approx 22.75"
Rear center of hub to fender passenger: approx 23.25"

I filled my gas tank last night, so the taco lean will be at its worst.

Stock height for 2nd gens seems to vary a bit, but from this an earlier thread (https://www.tacomaworld.com/threads/stock-supension-measurement-2nd-gen.122167/) it seems the average stock height for 2nd gens is:
Front: 20" to 20.5" (depending on taco lean, miles on truck, etc.)
Rear: approx 21.5" to 22"


So it seems that my truck has about a 2 to 2.5" lift in the front, and a 1 to 1.5" lift on the rear, compared to stock ride height.

 

thats a pro comp 3" lift kit with a rear add a leaf instead of block. also an early generation spc upper control arm.
