The shocks on my truck were pretty shot. Ordered some 5100's and got the rear ones installed today. Will have a shop do the front ones with the coil springs. These are the adjustable ride height so I'm hoping to get the 2" out of it like they claim. We will see! One of the easiest shock swaps I have done compared to 78 F150 and F250 SD. (That rust spot abover shock got hit with some undercoating after pic).
