I have been running the 4.5 RC full kit for about 4years and well the shocks are a wast of money. But the full 4.5kit is a great price and a good lift but the one thing i can say to you is if you plan on using this for a lot of offroading then buy the upper adj control arms. And dont put the 1" drop kit on until you get your kit installed and you drive it to see if you got any vibs coming from the drive line/transfer case if so put it on.
I started out with 4.5 then went to 6.5 with hockey puck and shackles. And no sye kit.
And dont have any problems will driving but each rig is different when lifted. So to each is there own.
