How long will stock shocks last with the trd springs? I also heard that you can have the trd springs with stocks for a long time is that true?

 

you hardly ever need to replace shocks unless you drive off road or on gravel all the time. I wouldnt worry too much about that... also, the increase in stiffness is increased 18% in the front, and 26% in the rear... so its hardly more impact on the shocks

 

the TRD springs aren't a huge difference on the shocks
you will be fine, just dont go offroading
