right now it has a stock shock and spring. My front shock is already leaking of shock oil.(definetely need to replace) So far the coil spring is still in good condition. And I was referring to the n95f of OME as a replacement.

 

If you have over 70,000 miles, your springs, shocks and steering stabilizer are shot.
If you want to do just shocks, order the OME HD shocks and they are a far better shock then the factory, but your suspension will still be sitting low.
