If you look at the 6" kit instructions and compare them to the 4" kit instructions, there isn't much difference between the two. Looks like you could easily convert it to a 4" kit if that would help you, p,us allow you to switch to a smaller size tire without looking bad to drop it a little more.
FRONT:
The 6" kit uses a preload spacer and a top spacer while the 4" kit just uses the top spacer. So if you have that preload spacer removed that'll lower the front.
REAR:
The 6" kit uses replacement rear control arms and panhard bar relocation bracket which isn't included in the 4" kit but will work on either. Both kits use a spacer above the coil so I assume the 4" kit just uses a smaller spacer. Therefore you
"should" be able to swap your rear coil spacer to the 4" kit rear spacer. Only other change would be to unbolt the bumpstop bracket and rotate it from the vertical position to the shorter horizontal position.
I'm not familiar with shops in LaPorte, you might have to drive to Houston.
