suspension help

[mtlman]

I have an 85 k5 with a 3" rancho lift running 33's im getting ready for some major work and would like to end up with 35 or 37's im thinking to remove rear blocks do the 4" shackle flip and do a 1" shackle up front will this work good for articulation or do i need a whole new lift?

that will work good. i have a 79 blazer and i have a 6 inch and have 38.5 boggers on it. i would suggest doing the shackle flip to get rid of the blocks then go to the junk yard and get a set of half ton suburban rear leaf springs. take the overload springs out and use them in the front. this will give you about a four inch lift and awesome flex.
