Thanks for the replys all... I don't have either a body lift or any lift on the rear springs. Actually I would like to research doing a mild lift on the rear, say 2 - 3 inches max. It seems like the rear sits lower than the front when I am packed up for a trip: 4 passengers, dog in the back, all the gear on top... even worse when towing my tent trailer.

But those bump stops only seem to allow only 2 - 3 inches of travel, and I'm pretty sure there should be more... The rear end doesn't seem to be sagging anymore than the first day we bought it new.

I think I'll try trimming an inch off of them, then explore options to lift the rear a couple of inches.

Thanks
