    My 72 has a 4" lift with blocks in the rear. Is this kind of lift causing my rear end to sit lower than the front? Should i go with a spring lift, or will it always sit like this? Any help appreciated. Thanks:confused:

    You need extra lift in the back just to be level. Mine has 6 inch tuff country ez rides up front so 6 inches of lift in front

    Back has 4 inch ORD shackle flip, 3 inch tuff country ez ride springs and ORD super shackles which gave it 1 1/2 to 2 inches lift. so close to 9 inches of lift in back. It is just level.

    2 inches extra in rear is about right for normal no cage heavy bumpers etc.

    Your stock springs are sagging. Common problem. Replace them with good used or get some lift springs and it will go away. It is not unusual for the rear to need an extra inch or so of lift to sit level.

    I use a zero rate in the back to keep it level.

    I [​IMG] saggy butt!

    That just sounds wrong, but my 72 has a bit of saggy butt and I kind of like the look. It goes with the psydo-stock look I have. SBG (saggy butt syndrome) is pretty common. They had a slight bit of SBG from the factory. 1"-2" more lift in the back than the front is usually the answer.

    Yup...the Blazer's butt is way heavier than a Pick-up and most spring manufactures make the lift springs off a pick-ups weight specs not a Blazer..
    I run 4" front and 5.5" rear.
