    Default 1997 Chevy Suburban 2500 7.4 454 4x4 lift and differential questions

    Hey I was wondering if there was a lift under 1k that is 4-6". I was also wondering if the differential (stock) in my truck is lockable or forever open?

    With a big-block 3/4 ton you should have a full-floating 14 bolt rear-end, which may have come with the Gov-lock locking differental. Look for the G80 code on the inside of your glovebox door.
