    swap 2.82 to 3.91 quick question!

    I've bought a 3.91 Getrag with 226mm axles to put on my 07 300C, do I need hubs also or I can reuse mine?

    Thanks alot guys,

    No problem! There's several venders here that have good prices on hubs, HHP, Speed logix, AllUSA motorsports, ect.
    I think their around $100ea. You will need the getrag pinnion bolt and 2 new axle nuts and the pink driveshaft bolts and nuts but call one of those shops and they will get youi ready for install.
