The LESU set up is the quickest and easiest way to do it. The cheapest way is a screw drive and stronger but your doing a lot more fabrication and there are a lot of people on here who have made them and I'm changing my dump from a LESU lift to a screw drive as I set here typing this and still not sure how it's going to work.
If you don't want to do a lot of fabrication go with the LESU lift it will work well and look good on your truck.
