These shackles give a minor drop in the rear of 1". Get your truck sitting level in an hour, easily installed, and of better quality than the OE parts being replaced. Constructed of solid steel, urethane bushings, and powder coated, these give you the look you're after.
Looks like a nice quality part, installed well.
On the ford F150 you do have to raise the bed to install which was surprising. Nothing to do with this part, but the install.
