…1st gen Titan with a 2” lift. Stock UCAs were making contact with the bucket on full articulation. These solved the problem. The front UCA bracket does need a minor shave. Invest in an inexpensive die grinder, and use a 1” diameter template to trace for the ADO UCA tube, leaving about 1/4” of material above the stock bracket hole (look at your front UCA bracket and you’ll know what I mean). You shouldn’t hit any of your main welds, and the shave is so minor that there shouldn't be any significant impact to structural integrity.
If you've come this far, may as well have ADO load these with the Moog joints and get the 3D printed caps. Install the grease fittings and fill em up. I prefer the AMSoil NLGI #2 grease. Nice, quiet, no UCS bucket contact ride.
