i got an 84 k5 with a 3in add a leaf kit and i wanna put 37s on it. does any body know if they will fit if i add a 3in body lift to it?

 

My '74 with a 3" body lift had to get some fender trimming to fit 33's while allowing full suspension flex while turning. A 3" spring lift isn't going to allow you to fit 37's without a LOT of work unless you do not intend to flex out the suspension...

 

so if you do get a total of 6inchs out of the deal. they WILL fit but like swartlkk said you really cant flex. i installed a 6inch suspension on my suburban with 38 12.50s on it at home, then drove it 5 miles to my work to finish it. they didnt rub as long as i didnt hit any hard bumps or turn the corner any faster then 2mph.

can always trim the fenders
