Hey Just for info purposes I bought a Mopar lift from the other vendor on eBay. (cnymopar) $990 plus tax since I am in NY. Was perfect transaction, and he only had 1 previous history on eBay. The other guy was overwhelmed and couldn't/ wouldn't sell at the time of purchase. I got the kit in 2 days.
For me the install was done at a dealer, pre arranged price of 4 labor hours, they surprised me with a $150 charge for the alignment, had I known earlier I would have told them not to do it, a local shop I could have had it done with a lifetime guarantee for same money.
I shopped around a few local dealers and the prices were all over the place, as high as $1200 down to about $550. I went with a $600 dealer since they do a lot of lifts, and it came out fine.
Another heads up, I went on dealers website and downloaded a 10% off coupon for a service, and gave it to the dealer when I dropped it off. They took it off the install but not the alignment.
Hope this long post helps.
