            RC 4.88 gears but missing some parts

            The wrong rear crush sleeve was sent with the kit but after purchasing the correct rear crush sleeve and front loaded carrier $240 later everything went smooth. Noticeable difference going from 3.21 to 4.88. MPG also went from 14.9 to 17.2
