To me, wire ties and zip ties are interchangeable. Whichever term my damaged mind comes up with first, LOL.
But if your leaf springs are weak/old, and new springs are not in the budget, there are leafspring helpers that won't destroy the shock mounts. ("Add a leaf"?]
Yes I mentioned the leaf spring helpers in original post. I guess it's the poor mans way to better leaf springs. O'reillys has the Superior ride effex ones for $70. Maybe hold me over till I get around to new leaf springs.
