I guess you are opposed to lowering with a dropped axle. What are your suggestions and what kind of truck do you have.
I have a 59 Suburban, a 54 1/2 ton, a 72 C-10, and a Blazer that's a bit too new to fit the criteria for this site. I'm an ASE certified Master Technician in the auto, heavy truck, collision repair, engine machining, and advanced engine performance categories, (22 certificate categories) with 50 years' experience as an automotive professional. I teach auto mechanics at McGavock High School in Nashville, and build NASCAR round track engines on the side.
Most people who attempt to alter ride height do not understand enough steering and suspension geometry to do it right, or safely. I grew up around a shop where we worked with straight axles as a matter of everyday routine, and the alignment man there wouldn't touch a dropped axle under any circumstances. He had 40+ years' experience with them, beginning in the 1920's.
You would be much better off converting to an independent suspension system on a front frame stub like a Nova or a Camaro, one that's been engineered to work properly with the benefit of millions of dollars' worth of factory research and development. My brother does engineering modeling for new designs for the automotive manufacturers, at the pay rate of $1,000.00 per day. Few, if any, hotrod "experts" can afford that type of expertise.
