Stock Shackle Lengths

[BGKYK5]

I am goofing around crunching numbers. What are the stock shackle lengths for 'mid 80's and up Blazers? I think they are 4.5" front and 4" rear, but can't recall exactly. I have 6" shackles on both ends now and have ditched the stock stuff.

TIA

Correct me if I'm wrong, but didn't they change them (refering to the fronts) at some point in the 80's, adding an extra 1/2 inch ? I thought I remembered reading that somewhere, but I could be mistaken.

 

[Mr-Jack]

are ya'll messuring from center of bolt hole to center of bolt hole or the full length of the shackle?

88-91 have the slightly longer variety IIRC; see "Tech Notes":
