My rig has 4" front leaf packs from a '72 K10, with a leaf removed. These were used in part because it had a big block at the time. I broke a main leaf this past weekend, so I am looking into replacements. I'm now running a small block, so weight isn't as much of an issue. I was told Wrangler (YJ) springs are about the same length and should be more flexy. What is the normal eye center to eye center measurement for the '72 K10? Somewhere in the 45-46" range? I want to compare to the YJ length before I buy any parts, and I'd prefer not to go by the measurement of my old abused springs. Thanks.

You're real close. I found a BDS catalog that shows 43" eye center to eye center. By the way, the YJ springs are the same length in case anyone cares - besides me.
I ordered some BDS YJ leaf packs. They have the full military wrap so in case I break another, we won't have to break out the welder again to finish the weekend.ecameron87

Will YJ leafs hold up the heavy front end of a blazer? They are super soft springs. It is a great swap for a samurai, but I don't know about a blazer. Maybe it would work with sway bars. How wide is the YJ leaf?

I thought that they were 44'' front and 52'' rear. I don't know about jeep parts on a full size, sound like trouble.
This is actually a 1-ton CJ-7 with mostly Chevy parts. I picked up the new springs yesterday, and they will work, but are a bit shorter than my old springs. Looks like I'll gain about an inch of wheelbase, but will need to move my (rear) shackle mount forward on the frame a bit to get the shackle angle correct. As long as this doesn't cause my driveshaft to pull apart at full droop, I'm OK with that. I think there is enough travel in it, but time will tell if I'll have to extend the drive shaft too.
Both the Chevy and YJ leaf packs are 2.5" wide.
