(i.e. last weekend) installed bilstein 5100s and the toytec
2" add-a-leaf. i drive mostly on-road with occasional light hauling (motorcycle, building supplies, etc.) and the rare, light off-roading.
i couldn't be happier with my choice. it handles great and the 2" is actually noticeable! i have the front bilsteins cranked up to 2.5" and was initially worried about over-stressing my cv joints, but in their neutral driving position they are only slightly angled. the rear rides a little stiffer with the aal, but it's a truck, not a mercedes, and it's not overly harsh.
if i had the money, i might have gone with the ome or toytec ultimate lift, but i just couldn't swing the extra dough.
let me know if you have any other specific questions -- i'd be happy to answer to the best of my knowledge!
