My experience with the Duff Classics have been that they do not stop axle wrap. They put a lot of stress on the axle perches. They will collapse letting the axle rotate and throw the drive line.
The double hiem shackle lets my bar float with out any bind. I built it with the TLAR method. I aligned the shackle with CV joint at the rear of the transfer case to minimize change in pinion angle. But with the short wheel base it gives me a high anti-squad figure. This means that when you stand on the throttle the suspension tends to lift the entire chassis extending the rear suspension. This is great for traction on the street. But on a steep hill climb it causes the front to loose traction. One day I hope to remedy this with a well designed link suspension.
