Can I put the same shocks from a GN onto my Riviera? I dont like the air shock set up and it weighs a lot too. Any ideas on options? I cant find really anything. I guess the main reason i want to swap them out is because i am trying to fit GN wheels in the back and they are to wide by 1/4in or so (they rub). I think it might be because the shocks dont stay inflated all the time but i still would like to take out the air system so i can lift the back by a 1/2 to 3/4in. Thanks for your info.
