with 5" of lift you will max out the ford shock when you flex, they will work on a road jeep or mild off road, they are about perfect for 3 1/2- 4" lift. I run the ford shocks front and rear with 2 1/2" lift, mine would bottom out if I didn't have extended bump stops. if you do decide to try them the ones you want are for the 4 wheel drive truck. 1997 f150 rear on front. 1974 f250 rear on rear.
