Spring rates?

Anyone happen to know the various spring rates on the 3rd gens, both front and rear?

Apparently there's loads of differences, or Toyota just likes making new part numbers:




(I see some repeats in there, like the 4WD 2.7s share with the 3.5 2WDs...)

Same case on the back end:



I'm asking because I'm considering getting a set of OR takeoff shocks on my SR, and I'm curious to see if there's an appreciable difference in what the spring rates would be, especially since in the rear you'd be swapping only shocks and not leaves.

 

so does anyone know what the stock rate is for an 2016 offroad......

 

Toytec had one tested @ 717... however which P/N it was is a crapshoot, I haven't bothered contacting them to clarify. I'm going to GUESS (emphasis here so no one takes it as gospel) that is was a '16 TRD Sport.

'16 TRD Off Road springs are progressive (rate changes as you compress), but figure somewhere in the same neighborhood, possibly a little lower though.

I know for certain that putting '16 TRD Off Road springs on a '16 4 cylinder 4x2 SR gives you more of a lift than you would expect, as I ended up about an inch higher than expected.
