    D1 Diff gears, price and ratios

    Now that I'm running the 33s my Disco is a teeny bit lazy, especially on the freeway in 5th. Being a 96 5-speed V8i, what would the factory ratios be (I'm too lazy to go looking for them) and what would be the best upgrade. 4:11s?

    Also, where do you get the new C/wheel and pinions an how much are they. I'm thinking ratio changes and maybe a couple of lockers might be on the cards.

    ps: Sorry Stooge

    3.54 is standard off the top of my head. Common changed to 4.11.

    OK,
    now that we are talking diff ratios, do they get stronger or weaker as you go up from 3.54?????
    are 4.7 (serries type) stronger then 4.11
    or
    3.54 stronger???

    The higher the ratio the less likely you are to break a diff or axle etc....

    Thats with all things being equal. Aftermarket CW/P's are supposed to be stronger than OE ones, and I understand 4.11's to be as strong or stronger than Factory 3.54. Likewise 4.11's should be stronger than 4.1's due to tooth sizes.
    Cheers

    Ya.... 4.11 will still be stronger and you will break less stuff on these than stockers just because of the torque multiplying effect. 4.11 on 35" will be stronger than 3.6's on 32"

    Going from 3.54 to 4.11. all other things being equal, you are less likely to break anything from the engine to the diff but more likely to break something from the diff to the wheel ie axle.

    Was talking to JC about something similar, except was wanting to reduce the gearing in low range as the autos are not that low. Now on the same vein, what about just changing the high range cog in the transfer case rather than 4:11's?
