Has anyone installed Rusty's RX3 res. shocks? Has anyone heard of any issues or concerns using these shocks? I purchased Rusty's 8" lift for my XJ and upgraded to the RX3 res. shock. The problem I'm having is the suspension is very stiff. I was told by a Rusty's tech to remove the Nitrogen from the shocks in 5# tries until I like the set up but do not go below 210#. They currently come precharge to 240#. What do u think??
