I second what 180sx says....stay away from the Rancho struts. They are crap with a capital C. I burned through 3 of them on the passenger side and 1 on the driver's side, rancho kept replacing them under warranty. At that time, I had the AC 2" coils on the front and rear of my Pathy. My assumption is that the Rancho struts just can not cope with the constant top-out stresses that the AC coils cause (although AC will swear to their dying breath that their coils are well within the shock's limits). I know other members on this forum have had better luck with the GR2s withstanding that abuse.
I finally got fed up with putting new struts on every 2 months and switched to the GR2s. At the same time, I switched to the OME HD coils up front. Even though the GR2s can handle supposedly the AC coils, I didn't want to take any chances (plus I just hated the sound of the struts topping out). Nothing worse than riding around with your buddy bragging about your new lift then trying to explain that god awful bang every time you hit a slight pot-hole or go over a speed bump. I left the AC coils out back. No problems since and that was about 5000 miles ago. The strut top-out issue went away completely. Unfortunately the OME coils in front didn't provide as much lift as the ACs in the back, so I had to add the 1" strut spacers sold at NX4 industries to level it out. The OME HD's ride nice in my opinion. I definitely don't feel like they are too stiff and I've still got my stock bumper on.
Based on my trials and tribulations, I would highly suggest the OME coils over the AC coils, at least in the front. And again.......stay away from the Ranchos, for the Pathfinders the GR2s are a much better product.
