Between 3-4" of lift. Hmm. How about BDS 3.5 lift springs, with the lifetime warranty they have. I have not heard of too many folks that were not satisfied with them. They have the military wraps as well, which is good. BDS Suspension Kit 409H Details
It is interesting to note: The use of extended shackles is recommended to clear the military wraps on the springs.
This is not a budget priced kit. However, due to the reviews from people who have purchased this kit, I would buy the kit if the suspension height I was looking for was in the range you stated. This kit is my preference.
