67-72 rear leaf springs vs 73-87
 

I have a pair of 52" leaf springs out of my 1978 K10 sitting around. They are 4 inch lift springs from Rough Country and are basically new. I have a 1969 K10 that I am thinking about lifting 4 inches to put 33's on it and I am wondering if these will bolt in. If the measurement from the center of the front eye bolt to the center pin is the same they should fit right? I have the 69 K10 in storage so getting to it to measure the springs is a problem at the moment.

Are you taking fronts or rears? The 69-72’s use 52” long x about 2.5” wide rear springs if I remember correctly so if the widths are the same it should work. I haven’t messed with a K 73-87 in a little bit so I don’t remember the lengths and widths. I know the front springs are Definitely longer on the 73-87 vs. the 67-72’s.
