The 2 leafs on the 2002 are slightly thicker than the three leafs on prior year models. (the individual leafs, not the leaf pack)

I have a 2002 with the SLR 3 leaf AAL and no load leaf with a one inch shackle. It rides nice and doesn't sag like it did when stock.

Stock it would bottom out on the freeway with four people and some gear in the back.
