Review on LUFT MEISTER 84176631 580-1108 PCS Front Strut Shock Absorber W/Magnetic Assembly With Spring For 2015-2021 Cadillac Escalade Tahoe Suburban Silverado GMC Sierra 1500 Yukon (XL) by Sean Moran

All the previous reviews complained about the air supply to a large shock and returned the item. Mine were tight as they should be to prevent leakage. press fit! I tried to lubricate the air line seal but was able to engage the fitting by hand. So I have the right tool for the job. The great canal is blocked. Barely squeezed and they snapped perfectly into place with very light pressure with pliers. This fitting must be airtight, otherwise air will escape. Just put 1100 miles on them. I could only think of why I had waited so long. Drive smoothly again.
