Review on Enhance Suspension Performance with Air Lift 52440 Air Lift Spacers by Satish Tegan

I don't think I needed this for my 3" lift on my Silverado Dually. I wasn't sure if I needed a 2" or 4" washer so I actually called Air Lift Tech Support before ordering, waited 45 minutes to speak to someone and they told me that i have for the 3" spacers i added under my leaf springs, i need to be used with the 4" spacers and i want them to compress more than they stretch (which oddly is the complete opposite of what says on their website). same distance as they are mounted, this is with 3" jack blocks. I almost didn't plan on using them at all once I had all the parts and could measure everything but I went with the, what the manufacturer told me to do and used them how he told me to. If I wasn't already under my truck, with all my tools ready and the truck already disassembled, I would probably send them back and get 2" spacers for my 3rd instead " Order lift. If you have a 3" riser or less, you probably don't need spacers at all, but if you plan to use them, use 2" spacers, not these. I've never found out exactly why they have an "indicator cutout". The instructions show the display notch but never mention what to display. He probably spent half an hour trying to figure out the indicator's notch point before concluding that it didn't matter how you phrased it.
