i have to agree
do it the right way and safe way
a full and legal lift will cost anywhere from 1000-4000 depending on what type you go with and what shop prices are
block lifts and the stuff your talking about where cool about 20 years ago now they realize how unsafe they are and barely anyone makes them
also the lifts you are talking about are for trailor queens for truck and car shows
some are used strictly for off road use only where teh truck isnt even street legal
call around to a suspention shops
get the know how and knowlage before makeing any decisions call you local saftey office for the laws on a lifted vehical
iowa is 11 inches maximum for it to be street legal anything after that has to be trailored
and is for off road use only
get the lift doen right

You do not use blocks on the front end
A 4 inch block off the front of a 85 k20. the previous owner wheeled this truck too the material block are made of is way too soft and gave away. the steering in this truck was terrible and the truck would wander.
