I have a 400ex and I dont want to spend much money on new a-arms so I looked at alba because their stuff is inexpensinve and I noticed that you can use stock shocks or upgrade long travel suspension. but then I noticed that the long travel shocks would have to be 19.75 inches long. so would trx 450r shocks fit with the alba long travel suspension. They did it in a video on youtube is the link.
