The rears are definitely too soft. I looked around but couldn't find the exact rate on the stock.Gents. as usual I have overloaded my axx w my mouth. I sold my RZR and picked up a 19 xx to be a twin sister pre runner. Looking to head to Baja the 14th-15th for some fun. I will do the speed clutch mod ,install radio,gps,intercom,roof,33" tires, and a light bar when I should be sleeping between working and doing all the interior tinwork on the race car. My question is shocks and springs. I just sent an email to shock therapy to see if they have an exchange set ready to go. I doubt they have time for me to ship mine back and forth. Does anybody know the factory spring rates on the stock shocks ? I have a full set from the race car I could play with if it would be a quick help. I don't feel like beating the rear diff up being too soft/overloaded w stuff.
If ST can't get to you in time, it looks like eibach offers new springs.

Also-consider putting a rubber mat underneath the rear diff.
