AlaskaVX,
Another opinion I got from a Bilstein dealer that outfits Baha racers was to spend a little more for a much better (and owner rebuildable) shock, the 7100 reservior shock.
This guy's opinion was that the 5150 was just more marketing hype and looks than substance.
He agreed that our front shock was a real problem to find a replacement for. He suggested looking into a upper conversion unit that accepts a standard eye to eye shock. A lot of the jeep guys use them.
Let us know what you end up with.
