I bet you are right. Probably Rancho.
That's good since anything you change to will be an improvement in ride quality.
All of the vendors here at CB sell really soft springs and great shocks.
The Rancho set up is known to be a little stiff.
But it is fine and stout. Have fun and play with it a bit just know that now you are here you will have a lot of suspensions to choose from and plenty of great advice to get you where you want/need to be.
Have fun. Good luck.
