hmmm re-index them? I would not IMHO. I would crank them again.

First off have you ever re-indexed them? If not, then doing a PML doesn't ever require re-indexing unless the stock spline position has been messed with.

If you crank them back up to the original position when you finished the PML, and it sags back down, it is time for new T-bars. Maybe some new shocks are in order too.

P.S.-If I were going to go with another 3" SL, then I would go with SLR
