I have an 04 F350 CCLB <acronym title="Four Wheel Drive">4x4</acronym>, I'm installing a 3" mini spring pack lift on the front, I'm wanting to raise the rear up as well.
I'm wanting to add a 5" rear block to replace my stock 350 block, Do I need a FLAT OR TAPERED BLOCK? Or should I just install a 1" ADD A LEAF?
I'm leaning towards the block but confused on the tapered or flat?
