Looks like the local mountains where it is cold October through April. Alabama OK the heater may not have a high priority but with snow on the fenders a heater should remain on the list! ?
I have the Mopar lift and had a clunk about a week after the install. What my problem was a loose bolt on the torsion bar end link (left upper rear). Torqued the end links and the clunk has not been heard from since.
Hope you able to get it worked out. I continue to get good customer service from Oracle. Just last week I rewired the Halo’s on my Oculus headlights. I reached out through this forum with questions to JP and he got back with me with the information I needed. Try JP he has helped me.
