Yep. $4k for parts and installation.Kelderman makes a bad @$$ system, but its big bucks.
It is just blocks. I thought about just doing the rear... but the ride must be amazing if you do the truck... plus there is a cool factor of being able to raise and lower your truck on the fly.How is your rear lifted? If its just blocks, air lift has an rear end system that converts it totally to air, for a fraction of the cost.
