I agree with Sparky66, that shock absorbers should never influence ride height.
My leaf springs are 5-leaf Global West (L-10?) springs, which sit basically flat, right out of the box. My car has some thin, pinion angle wedges under the axle, which probably bring the car down another 3/8Ē.
The front springs are whatever Moog springs are used to produce the aftermarket 540 lb/in springs, and I just kept cutting them down until the lower arms were parallel with the ground, and the front sat appropriately compared to the rear.
