Just to give people an idea of how long and what it takes to do. Not just my kit but any other kit out there also. A good mechanic with the right tools can install 4-5 hours. That’s what a shop should charge. Plus an hour for a 4 wheel alignment. Just a heads up.
When the vehicle has options from the factory (I.e. factory lift) they can not deny a warranty claim based on those parts. Now if you install or have someone else install a lift and let’s say your cv boot leaks grease they (the dealership) can deny that warranty claim not the manufacturer.
