The shocks, as far as I know, were custom built by KYB for the VehiCROSS. No other Isuzu has our shocks. There may still be some new shocks available, but they are in the $350-$400 range PER SHOCK. If you look at them the shocks have little reservoirs on them to help cool the oil in the shock to prevent cavitation (creating air bubbles in the oil) during high cycle usage, like blasting across the desert during the Baja 500/1000. They are pretty cool little pieces of engineering.
"The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong, it usually turns out to be impossible to get at or repair."
