i have also heard that the lift and the springs are too much, but i see people doing it more and more. i had a lift on mine, it really helped in the ruts i recomend it if you are wanting to slid over stuff. i never had the longtravel so i dont know much about them, i have heard good stuff about them and they sound like they are the way to go if you want a lift while still having a nice ride. spacers would help, you proubly wouldnt need them in the rear but they would help in the front if you got wider tires.
