you have to buy the cups and bottom brackets for the front, you can run a 2600lb bag in the front but most people run a 2500lb bag. 2600 will give you more lift and better ride. you need to knoch out the frame in the front so the lower control arms can go up in the frame. also you have to buy a set of drop spindals. if you have never done a bag set up before it can be hard. you need to make sure the bag dont rub,and will colipase flat. also you can make shock mount in the front for a better ride. i use nissan truck shocks for 95% of my jobs. hope this helps you. spark it or park it!
