After first offroad trip......Im convinced I want a lift now

I was thinking just the 5100's all around, but Im not sure I understand if I need the AAL as well? And the difference between the stock springs and other ones

 

...but it WILL improve your breakover and departure angles.

 

5100s in the front have an adjustable spring perch that provides lift.

5100s in the back do not change height, just shock damping. To raise the back you need an add-a-leaf, lift block, or replacement spring pack. Of these, add-a-leaf is the best "bang for the buck" but replacement leaf pack provides the best ride.
