While i'm sure having a true military wrap will help solve your spring bending issue, I think just adding a spring clamp closer to the end of the spring would accomplish the same thing. I did it with mine. I just took some 1/8" plate and wrapped it around the 2 main leafs (in the shape of a "C" then put a bolt through the plate to hold it in place. I haven't had an issue since.
I was going to do that also, I only want to buy one more set of leaf springs.
