Re: Rear Spring Questions

OK, so I went out and measured. I hope this makes sense?!?

The long-bed 1/2ton springs ('86):
52" i-2-i, 5 leaf plus the short/flat/thick leaf (overload?) so 6 total - the 5th leaf is about the same length as the 6th (overload?) leaf but matches the arch of the rest of the pack. It is not as thick as the 6th leaf, but thicker than the rest of the pack

My K5 springs ('82):
52" i-2-i, 4 leaf plus the short/flat/thick leaf (overload?) so 5 total - the arch of the pack as a whole is a lot flatter than the 1/2ton long-bed pack.
It occurs to me that since the springs on the long-bed are less than 10years/under 10k, it might just be that the springs on the K5 are just "flat" worn out... literaly.

To confuse myself even more, my short-bed 1/2ton springs ('87):
56" i-2-i, 5 leaf plus the short/flat/thick leaf (overload?) so 6 total - the 5th leaf although shorter than the 4th leaf doesn't appear to be out of line with the progressive shortening of the leafs and matches the arch of the rest of the pack. The frame does have the holes there so I could move the rear shackle perch in and run the 52" springs.


I guess I should just put a flat edge across the eyes and measure down to the top of the spring pack. If the flip kit (5-6") minus that difference works out to ~3" lower than I am at now then I should be golden, right.........
