    No they do not. The SRT halfshafts fit the R/T hubs though so your good on the wheel side of the assembly.

    No, r/t diff.=210mm srt diff =215mm. You need the diff, shaft's, hubs. rear drive shaft piece.
    hey what do ya know, I just happen to have a whole setup comming up for sale as soon as I swap my new set in.(waiting on a drive shaft tail)

    He doesn't need the hubs if going from R/T to SRT, just the pumpkin, axles, and drive shaft. We spent a LOT of time at Cam's comparing 5.7 and 6.1 hubs. They're the same with the same part number.

    Ok, Thank's for the info. It's probably good to get hubs to if possible for the stud's should they get messed up along the line, their exp.$

    I recently swapped my RT diff out for the SRT unit to get the 3.06 gear and what has been stated is correct... You only need the SRT halfshafts, the rear of the SRT driveshaft and the pumpkin.

    A note of caution... make sure there are tone rings on the axles going in, or they will have to be carefully removed from the stock axles and installed on the SRT axles... You wiill go in instant limp mode if both are missing... car no go, nada... nix... I found out the hard way and it cost me an extra day while the shop redid the job right...

    Love the new gear tho!!!

    My gas mileage is about the same highway and slightly better city than before the gear swap.
