I thought that i heard somone say somthing about a shorty box seat on a 03 440 Pro X racer. Did i hear it wrong because i have never heard of somthing like that. have you.

they must be refering to " pro x shorty seat" and the only thing i can come up with is that the foam inside these seats are box shaped..

my shorty seat came off a 03 pro-x race sled,looks like a std short seat, the inner foam insert is square [box like }
