I'm doing re-arch and add a leaf next week. Re-arch because they've sagged, add a leaf to address the extra weight and to slow down eventual sagging
But I wouldn't call this a rear end lift as its more of a rear end repair. I may gain a tiny bit of height over stock with this repair, but that's not my goal.
I'm going this route partly for economics as it will be $275 for the repair. Adding a shackle won't fix the sagging leafs and may even exacerbate the problem.
I may consider shackles later but not until this problem is fixed.
