I am getting a 4'' suspension lift on my 2005 f-150 in the next few month. I have been doing a lot of research to see what brand to go with and i had a few comapnies i was researching. however, over the last few months it appears that the reputable companies who offered the 4'' lift are no longer carrying the 4''. 6 '' is the smallest lift possible. BDS still carries a 4'' but I want to look into other good companies. does anybody know why these companies are gong away with the 4'' lift?
