How to find out which coil springs are in my truck?

hello all,

I have a taco sport 4x4 2017 and am trying to find out what they mean by "sport Tuned Suspension" - is it just the Hitachi shocks and Toyo tires or does Toyota put different COIL SPRINGS in the sport vs the off road.

(my goal is to get a less stiff / bumpy ride - I searched the threads and some are suggesting replacing the Hitachi shocks with the bilsteins. 5100. That great but are the coil springs the same in sport and off road. If so I wouldn't have to replace those as well.

I went to Toyota / brochure - and compared but it doesn't say - please SEE ATTACHED comparison under suspension

Thanks for the help in advance MUCH appreciated!

 

Thread revival. I have the same question, are the springs the same between the sport and off road?
