Good idea but not thought through well enough
Air bag fits in just right with suspension at rest. Customer drives over a 6 inch curb on daily bases and axle travel extension tore bags off there mounts. Air Lift pro-rated warranty and second set failed also. Modifications to mounts were made and so far so good.
Really nice struts
I already had a 3.5" lift on my truck, I used the 1st marker on these shocks to add 0.5" to the front end of my truck and correct the slight rake that remained... it did the trick! My truck has 157k- it was time for new struts and these Bilsteins make a huge difference in the ride, much smoother!
