Well i have looked into this for a long time. and i will have the money in a while. i am wondering about one thing for the rear though. should i go with 6 inch springs, 4 inch springs and the 2.5 inch shackle flip, or 2 inch springs and the 4 inch shackle flip? i would prefer to do a shackle flip because i am sure you get more flex out of it. i would prefer to do the 4 inch springs with the 2.5 flip. i will be switching to a 14ff at the same time. any input to this would help. Grant. 1974 Chevy Blazer Cheyanne. but it is on 33's now, with saggy old springs. i am in Yuma Arizona if ya got any parts for me.
