Firstly the screws were not long enough to tighten the screws properly, washers had to be added. Installing without spacers, I had to jack up the truck 1/4" to get it in. So it sat on the axle. In effect, the truck turned into a hardtail. Since I was removing worn out airbags, I needed something. So I did cut it to length on a cut off saw. Now they are 1" over axle like they should be. Needless to say all of this made them a PITA royalty to set up. After all of this I sent the front ones back.
