Yeah, those shocks look like OFNA. I would think if it was the "jammin" version though, the chassis braces to the front/rear bullks would be alloy as I thought those rigs were kind of the "upgraded" version. Looks like your rear one has a chunk out of it.
Although, the pipe looks like it say's "platinum" on it, which might be a dynamite pipe. Could just have been an add on.
