No settling as of yet that I can tell, the rear has a smittybilt src bumper and full size spare. I have about 4000 miles on the lift now, with 2200 or so miles with her loaded down with the full family (4 ladies and myself) and their accompanying luggage. Wish I would have measured the lift with everything in it, but didn't think about it. I will say on the long trip it handled well. Part of the trip was going through the Great Smokey Mountains. I drove this pre lift and tires earlier in the year, and can say there was noticeable performance difference. She tended to want to run in 4th gear going up hill a lot more than she did without the lift and tires. The corners were a breeze, without any extra body roll. I will try to remeasure at the same location I did before to let you all know if there has been any settling of the springs.
