If your truck is more than a year or two old, and you decide to do it, get yourself can of good penetrating oil, then spray the bolts holding the existing spring stops with the penetrating oil every day for a week or so before you do the work.
Removing three of the four bolts and installing the Timbrens on my truck took about 30 minutes... Drilling out and te-tapping the fourth bolt hole - for the bolt that sheered flush with the frame - took about four hours!!!!
Still worth doing, though! I had a MUCH better ride this year while towing, and it was nice when towing at night, to have the headlights actually hitting the road in front of me!
