They say it's 3 inches but it's more like 5 or 6 inches. I put them on a new set of struts thinking it was the new springs but after 6 months the front mine was still an inch higher than the rear, I took them off and got a 2 inch kit and he finally leveled the truck. They are made from quality materials and are fairly easy to install for those who are mechanically inclined. But he raised the front too high. I would definitely recommend them to anyone who needs to level their car. Just remember that 3 inches is more like 5 inches and 2 inches is more like 3 inches.
