leaf spring bolt sizes?

[bigbadchev84]

i am putting a lift on my new truck and forgot to get measurements before i came to work, i need to know the sizes of all leaf spring bolts front and rear, and the bolt size for the front springs rear shackle that goes through the frame, thanks

Most of the GM trucks I've fooled with used 9/16 bolts in the rear,and either 9/16 or 5/8 in the front spring(frontmost bushing,I've seen both sizes)and 7/16 in the rear shackle of the front spring--sorry,but I dont know the exact length,but about 4 or 5 inches should be about right. /forums/images/graemlins/crazy.gif

4 1/2" long

Front springs, 9/16 in the front main eye, 7/16 in the rear eye and upper shackle, unless it's 88 or newer, then 1/2"

Rears all 9/16

5/8 was not used.
