Those appear to be factory FORD blocks on top of square tube.


Any block is questionable; the higher, the worse, as they increase axle-wrap exponentially, giving the axle immense leverage against the springs.


Best fix is to have a good spring-shop custom arch a set that eliminates the blocks completely.

thats interesting? i do know i have different front springs, i have found a stanley spring sticker. as far as the rears i do not know. my truck sits very level. no real rake to speak of. the height seams good nothing out of the ordinary. it's lower then my buddies 98.5 with leveling kit im going to measure the space inbetween frame and spring when it stops raining
