about 25k on these leaf packs when the picture was taken. i had the origional springs replaced under warranty at 30k because they were so saggy. these are the 2nd set of OE springs in the XJ. i didn't put the shackles on until these springs had 20k on them. within 5k, this is what they looked like.
i towed a 13 foot boat accross town once. that's it.
here they are after a little over 2,000 miles with the shackles:
just under 4k after installing the shackles.
i have no other modifications on the rear. no blocks or anything else.
there's a reason most people on forums like jeepforum will tell you to get the AAL instead of the shackle when it comes to budget boosts, because it wrecks the weak master leaves on OE packs.
look at the stock leaf spring. the master leaf towards the rear has a long expanse where its the only leaf. when there are other leaves there, that's great to keep it from bending the wrong way. aftermarket leaves usually have the 2nd leaf much longer than the factory spring's 2nd leaf, which makes the aftermarket leaves last longer.
they bend the leaves because the stock packs don't have anything but the master leaf in the rear 1/3 or so of the spring, where the shackle is.
i notice others here say they havn't bent their stock master leaves, but they have added leaves from other packs, sustaining the arch of the master leaf. i said stock packs. what you're talking about are no longer stock.
