What is the eye to eye you need to fit for the 6" bike? If not sure check archives of bike manufacture. Msg me privately on pinkbike for my cell and we can do this deal if you want!
OK from what i see online with FOX your bike or your brothers comes with a Van R 7.875(i to i) so YES this rear shock will fit perfectly! I gather from our phone call it is a 2007 Haro X6.
np, what is your i to i on the bike you want to put it on?...i always check website of bike maker and then to make sure measure from middle of one bolt to the other.
