I've got the DV8 headlights as well. Really like them but I had a set (just the passenger side) go out pretty soon after I got them installed. Not sure what happened there. DV8 was really good about getting me a new set though. New lights works great - no issues so far.
Finally, after a 3 month wait, I got everything put on in my signature. Did a beadlock match to the factory paint as well. Turned out good if I do say so myself. 5.38 gears did it right too - running at about 2500 RPM on the freeway at 75mph in 8th. Not having to hunt either.
There's no way it's 185 lbs - that's the box weight. They ship it on a pallet so that's probably why. Quadratec says it's 45 lbs. That seems about right. I didn't need any help lifting at all.
