Howdy, I have an 02 Tahoe that I had lowered 10 years ago by means of lowering springs and aftermarket torsion keys. I just purchased the Ultimate Cornering Package from a vendor on here. My question is, would I need to install factory torsion keys or just adjust the aftermarket ones to a factory setting if possible. The Tahoe has been lowered for so long I don't even remember the brand name of the parts anymore. My kit will be here next week so I'm just making sure I have all of the parts lined up and ready to install.
