72 vs 73 up springs
I'm going to do a 2" lift on our truck - looking at doing springs in front and maybe blocks or add-a-leak in rear. You can find all kinds of stuff for 73 up
http://67-72chevytrucks.com/vboard/s...d.php?t=780186 Why wont 73 up spring lift kit work on the 72?

Re: 72 vs 73 up springs
eye to eye length change 73-up .
and fyi : add-a-leafs = harder ride . most of them i ever put in they say the ride sucked and wanted removed and new packs or block to fix it .

Re: 72 vs 73 up springs
I think a majority of rear springs were the same length for k10’s between 69-72 and 73-87. If they were k20-k30, they were longer as well in the rear.
