    Hello! Spring is coming and i am thinking about final drives. Now i have S80 J4D 4.4FD Spec96 LSD gearbox. All time i am thinking about searching and instaling 4.785FD from 98spec ITR. But all time i am thinking if can feel difference and how short it would be! Maybe somebody can give your opinion about this thing. Thanks! :)

    OO okey! I readed that it is the best OEM gearbox and the shortest too! Just interest me how much rpm are on 60mph or 100km/h in 5th gear? :) And one more thing are that i am looking on Mfactory Final Drive, because i have been looked on DC2 ITR OEM 4.785FD kit, but havent seen that somebody sell it! ;) Thanks! :)

    shouldn't be any real difference between the oem 4.785 and the m factory 4.7 FD. depends which is easier to get and what condition its in. I've used a 4.928 FD in the past and now have a Mfactory 4.7 FD in my ek9, much better to drive than the standard 4.4 FD.

    You won't notice much with 4.7

    If you're going for the simple budget route of upgrading your gearset, go for 4.9.

    For the effort, it's either you go for a 4.9fd or a shorter gearset kit.

    Great time to put new synchros in as well.
