Originally Valley Springs. But... After further research I canceled my spring order. They fixed the sagging issue but in trade limited the coil flexibility. I think it's a good spring solution for on road and increasing ride height.

I'm working with Coil Spring Specialties now. They designed springs for me 7 years ago for my 1992 Montero. I drove it off road for over 2 years without any sagging or other issues.

The springs will be a progressive rate coil based on the stock spring rate but able to carry higher load (extra 500 lbs) and 2.5" higher ride height. Their initial quote was under $300 /pair. <img src="/forums/images/graemlins/smile.gif" alt="" />

OME is a good option but $150 + Shipping for 1" height increase is silly. I haven't found any other options.
