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 :waytogo:
 
4" front, just replaced mine

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.
