My rear passenger side has been making noises for awhile probably b4 my one year warranty was up got it checked today rear passenger side is blown, should i just put my stock ones back in and leave the stance springs?

 

Stance charges about $100 each to have the shocks replaced. I'm getting all four of mine done right now. You shouldn't have any issues running your OEM shocks with the Stance spring for a short time. It's just like running Eibachs or Tein H_tech lowering springs.
