Question is how tall a block to achieve the same lift ? 4" ? Thanks

Do not use blocks for lift in the front end. Get springs. Where did you get new shackle hangers for the front? Anyhow, you can use lift blocks in the rear but not the front. It is dangerous and unsafe. You can use a 1" zero rate because it acts like a spring in the pack, other than that, no blocks in the front.

Please post some pics of our current setup.
