M1151A1 rear variable springs

[rcamacho]

I have an 1151A1 with a broken rear variable spring. I’m looking at the standard 10K variable springs vs the HD variable springs. Can the 10K variable springs be used (I’m not planning on running armor or heavy payload on this one). The UOC calls for the HD spring but these are comparatively expensive and harder to find. Related, I’ve not been able to find spring specs on these parts in rate/in or base wire diameter.

HD Variable NSN 5360-01-524-6029
10k Variable NSN 5360-01-357-2413

They are both variable rate springs, so I don't think you'll find a compression rate for them.

for the -2413 springs, Parttarget has all the info you are asking other than the rate
4.5" inside diameter
15.45" length
1.26" wire diameter

For the other one (-6029) I could only find free length of 16", which is basically the same as the others (15.45") and wire diameter of 1.300 at the thick end

Don't quote me for certain, but I believe that the same length springs all use the same mounts so they SHOULD be able to be interchanged.
