Not quite that much, MZ-N10. My local Isuzu dealer wanted $425 + tax apieces. But others posted that St Charles Isuzu will ship them to you for something like $375 apiece, and you may be able to save yourself the tax that way.

I recently went through all of this research myself, and considered the Ranchos, but ended up going with Bilsteins (B46-1738-H1 and B46-1739-H1 are the part numbers). I am very happy with them, too. I paid about $255 for the set of them (delivered) and installed them myself in an afternoon. And I was able to drive Peewog's VX with stock shocks in good condition (although with 77k miles on them) to compare, and we both found the ride and body motion control almost identical between the two setups.

Good luck!
