I used pro comp es 9000's on my 09 2wd with the spacer. I got front one that were made for 0-3" spacer and stock height tears. They are like $40/each. There are better brands but these were good enough for me. The 2" spacer leaves the shock over extended some kits come with a cheap little screw on extended but I prefer just buying the right shock. I am sure bilstein and the other brands bane the same ones as procomp for 2wd's. Not sure how much they cost.
