I'd like to know what people think of the Z-box if anyone is using them, specifically how they hold up over the long haul and if they would consider them durable enough for a FSJ with one ton axles and 40" tires.
There is a product review at: http://www.4x4wire.com/jeep/reviews/zboxes02/
They are available, and there is a better pic of them at: http://www.4wd.com
I am asking because from what I've seen Revolvers don't open fully and the springs actually twist at the fixed end leading to breakage because they don't flex with the dropping axle. Going with a military wrap spring would help the spring last longer, but it won't fit the Revolver shackle and would also not flex as well.
Something like the Z-box, if durable for FSJ use would possibly be a good compliment to the new drop shackles some of us are looking forward to.
Whatchy'all think?
