I installed two 3" and four 2" BLs in the last 2 years. All BLs were from Performance Accessories. The BLs came with all parts that were needed.
Yes it´s more work than a 1" BL. But extending the filler hose, installing a TC shifter bracket and welding a piece in the tranny shifter isn´t that difficult.
All BL installs were done after 4-5 hours and there were never problems after that.
BTW if you don´t want such a TC shifter bracket you could install a Skyjacker TC shifter relocation bracket. That worked with 2 BL and the stock TC skid and now with the 2 BL and a 3.5" higher TC skid.
