2nd Gen Non-Engine/Transmission Lowering a 3500 4x4

[Kraig]

Everybody wants to raise a truck, but my 3500 is already too tall to load easily and my wife can't get in it very well (we're over 50 now). I'm only looking to lower it 2-3". Blocks in the rear spring can be changed, but can shorter springs be put in the front without messing up the geometry for steering and such? Does anyone sell a shorter spring? Any suggestions for spring suppliers?
Thanks,
Kraig

Forgot to mention, my 3500 is a 1998.5.
