I'm looking for a pair of 500 lb, 2.5"/65mm ID coilover springs, 6-8" long. I'll also consider other spring rates +/- about 50 lbs.

$40 shipped for the pair or a straight trade for my 7x2.5" 350 lb/in Chinese springs.

If you have Swift or Hyperco, let me know how much you want for them and we'll talk.

 

If end up going new... Amazon has the best prices that I've found.

 

I still haven't figured out the super secret keyword that gets me to the useful springs on Amazon. EBay is the cheapest I've found by a fair margin, though they're hidden nearly as well.
