Update for anyone that finds / reads this thread . Giant is now selling this as a 3 link setup for 3500 less bed cage or 2100 as a weld it your self kit . He doesn’t make the bed cage anymore so that’s a little bit of a bummer but sells the upper bracket for shock / bypass mounting so it isn’t that bad. and says that they can pull around 24” of travel out of it. I’m stacking up parts now to do this swap now and if I get a chance will post up pics. I think it’s a much overlooked affordable option that allows you to keep a lot of your bed which is huge for a DD situation
