    Aftermarket Rear....

    what is the most absolute bullet proof *gorilla proof* rear end out there for the 98-02 F body...i have blown up my stock 10 bolt 3 damn times now...and am not breakin 400rwhp...heres my list of boo-boos..

    1 set bent axles...replaced with moser forged 28 splined
    ta girdle installed
    2x auburn pro series diffs..grenaded spider gears...
    2x sets of 3:73 gears motive and richmond ..grenaded back to stockers..

    i will hopefully be making mid 400+numbers hp/tq and with the spray look to be about 700 ish..i need something that is NOT going to $HIT on me...

    m6 go 4.11 I went 31 spline should be pletty. but if your the parinoid type you could get what is it a 40? the higher spline you go the stronger it is but you can't have posi with anything over 31

    I went with a TruTrac diff. 31 spline axles.

    Plan on launching on the bottle?? Might want to go locker with 33 or larger splined axles.

    i thought the SD60 was the baddest rear out there? and no i will not launch off the bottle..hopefully i can make enough tq down low i wont need to...and the car will be driven on the street too ..so that eliminates the spool

    Not a fan of the torque arm mounts on the Dana or the 12 bolt.

    If you are launching off the bottle...TruTrac with 31 spline axles.

    well so far i am gathering that this would be the best rear...

    M9 /with TruTrac/ with 31 spline axles/ 4:10 gears is that gorilla proof?

    The M9 is a different housing than a 9".

    I have a car I consider to be mostly street...and I have 4.11's. 75MPH is 2,000RPM in 6th gear.

    yea i was hoping to keep 85 mph and about 1500 rpms...thats why i got a 6 spd car...maby when i get tick performance to rebuild it they can do something w/ the gearing? w/ the price of gas and the dreams of a power tour........

    With 3.42's (stock) you are spinning 1850RPM at 85MPH.
    With 3.73's you are spinning 2050RPM at 85MPH.
    With 4.11's you are spinning 2250RPM at 85MPH.

    Do NOT rebuild a 10 bolt.

    Moser 9"
    It is a complete bolt in rear end.

    I thought there were problems with the Moser torque arm bolts? Or is that just on the 12 bolt?
