Will these work with 4" lift springs or just factory

The bushing sizes included are designed for stock spring eyelets. After market leaf springs that use a factory sized leaf spring and shackle bushing should be compatible. Many of the brands use a proprietary sizing though. We would suggest stock springs for best chance of trouble free fit.

Would the 3/4in lift require adjustments to the drivetrain or steering?

No, the minor boost from these shackles is not enough to require other changes.
