    What gear ratio does the rear have to have if you put 4:88 in it and not have to replace the carier ?

    4.11, 4.56 and up, or you can pick up the 4.88 thick gear and it will work on the other carriers.

    The carrier split is 4:10 & down and 4:56 & up. You can get thick gears (4:56, 4:88, 5:13) to use with your 4:10 & down carrier. /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif
