    capri ZF side gears change

    Hi can anyone confirm if it possible to change the side gears to 18t in a capri atlas lsd and is it viable financially. A quick look the gears seem to be £100 a piece but not sure if that is for a motorsport diff. There are couple for sale just seeing if it is worthwhile or buy new when i am ready.

    Thanks

    Dave

    If it's std ZF diff then the diff usually need machining out to fit the large diameter halfshafts.

    I think if thats the case then it would be easier just to get a 18t one new and cheaper overall.

    That indeed sounds like a wise decision. It's better to start with new instead of spending a lot of money on someones knackered second hand LSD. We have all been there at sometime buying used competition parts that are worn out.

    yes, you just need to machine the casing to fit the bigger shafts through, straight swap the side gears out, if you already have an lsd then its cost effective to do, buying a new zf diff is just about impossible, you can get the chinese copies and they come in 18t and are motorsport ramp angles inside already. i can do the casing for you if you dont have any luck with the machine shops.

    Thanks, it's all future thinking but seeing a diff for sale made me think was it worth buying and converting.

    "oldskoolrools" what would it cost to convert the diff and setup in an axle ? The diff i had in mind is the one on sale on here which i believe you have seen etc.


    Has anyone had any experience with the chinese ZF copies i have seen them on ebay for around £600.
