Nix the cinder blocks, BAD IDEA....
Installing a lift is fairly easy, just time consuming. Make sure some of your tools include a big cut off wheel or a blue tipped wrench, as you will probably have to cut out the old bolts.
Allow plenty of time, and have a vehicle around for parts running. There will be some odds and ends you come across that will need to be replaced....(Longer brake lines)
Two floor jacks are helpful.
Are you already geared for the future bigger tires? Moost peoople run ooutta money for the gear swap after spending money on the lift and are not happy with the results....
