Review on 🔧 Readylift 66-2094 4-Inch Rear Block Kit - Ford Super Duty (1-Piece Drive Shaft Only), Silver - 1999-2010 by Wes Thao

Block quality is as expected but the level is a bit misleading. The block has a 4" to 3" taper. So your stroke is only about 1" if you are replacing a 2" block, not a 2" block. The block got the rake back to my truck, but not as much as the stock. If I were to do it again, I would buy a 5" block to match my 2" level to bring the truck back into inventory. The block appears to be of good quality but not as much lift as I was expecting.
