Old air shocks. Still held air. I went with KYB 5512's I think. I had bought them about 5 yrs ago when I did the front, but just never got around to installing them. The only "weird" part to all of this are the shocks. The top of them almost, and I mean almost, hits the bottom of the shock mount. They hit until I tightened everything down, then they pulled away ever so slightly. Hopefully this is normal and ok. I double and triple checked that I had the right shock according to rock auto and summit racing.
