I have a practically new Readylift leveling kit for a 2019 to current AT4. Part number 69-3920. It has about 1500 miles on it and zero miles are on the upper control arms. I switched over to a Readylift 6" kit, which uses the same upper control arms so I left the ones from the leveling kit on it. Perfect condition. I feel it's worth $500 plus shipping since it's $659 new, but I'm open to realistic offers. Thanks in advance.
