The only reason they do not extend as far as the full flights is becuse of where the shock mounts to the arm, as in the fullflight mount is 1" (aprox.) higher then the Alba mount. I don't think the fullflights have any more travel then the Alba's, they just make the quad sit higher in the front. This is assuming that the frame will not bottom out with the Alba's which I do not know yet. I am awaiting Alba's answer as to what the LT shock length is suppose to be for these arms. I was figuring for an 18" ish shock and yes that would make it even with the fullflights, as far as how far down the lower arm goes, like in my comparison pic
