Hey guys. A friend has a 2013 rzr 800 50". His rear is sagging pretty good. I installed racertech dual rate springs on factory shocks. It helped a bit but did not bring the back up back as high as it used to be. My question is would new shocks actually help with picking the rear up. If so what kind of shocks can I get and use the dual rate springs that I have Noe. Also he has duel Looney tuned exhaust so he cannot have a shock with a mounted reservoir. Much appreciated for any help.
