I wondered about that - the OME rear shocks go for about $82 a piece, and thay's a lot of coin just to get a yellow shock.
I don't know if these are available in the US, but, when I bought my GV it came with yellow Monroe 4x4 Adventure shocks in the rear - at least that's what the sticker says - I haven't been able to find much about them, but yesterday, when I went to pick up my Pajero from the radiator guy, there was a pickup there with Monroe 4x4 Adventure shocks on the front - those are the only two vehicles I ever seen with them.
