I can't say about the BAL fast jack, I do have the strong arm stabilizer kit installed, and I have forgotten to lock the stabilizers. It doesn't take long to realize it. The DW can walk from front to back with me sitting in the slider to feel movement and that I have forgot to secure all points. I couldn't go without them now.
