for the rear its quite easy because its a solid axle suspended by leaf springs. for the front of your 1500 its hard because you have independent front suspension with torsion bar suspension. kelderman mfg is working on a front setup for the dodge, they already have one for the chevy. it replaces your torsion key i believe with an air bag set up, but i dont think its possible to actually drive down the road with it deflated or inflated at any other psi then it is set up with. in the link is the setup keldermanmfg.com has for the chevy. it really cuts down on ground clearance....if you dont need it its cool. but drastically adjusting your IFS torision bar setup 0-3 inches is something that needs an alignment. unless the system has some new technogoly that aligns the wheels as it lifts its almost all show and no go. on the other hand....their solid front axle dodge and ford lifts are awesome. definitely the way im going next.
those are good and all, pretty inventive, but....you think you could drive with it at any other PSI then what it is set up at. we all know if you adjust your torsion bar that much you NEED an alignment.
I thought with that Porkchop kit shown you would get rid of the torsion bars? I want a suspension lift that doesnt require me to crank on the torsion bars and isnt 6" up. I just dont like the looks of the body lifts either. I thought that maybe a airbag setup would allow me to get that 3-4" jacked look but then for letting the woman drive it around it wouldnt require a step ladder to get in.
