Just finished the install I did fj trail teams springs and bilstein shocks 1/2 toytec spacer and firestone air bags. The Ride is great and the bilsteins have a lot more rebound dampening then the stockers. As others have said this a great mod I would never go back to stock.Side note the bilsteins that came with the springs were a lot bigger around than the stock runner shocks.Lifted it nice and the boards are dead level.The pic of the seven pin harness is the two air fills for the bags. Thanks to Gatorose,Chris and Swamp Rider for all your help. Next up tires!
