That is such a sweet combo wish i had tons of cash around to buy a truck right now.

Norcal was right 410's are a $1,600 option on the FX4 Package. It still showed a 11,300 Lb. tow rating with 373's. Don't think it would be worth that much for the same tow rating, unless I missed something!

There's an FX4 for sale in Baltimore area dealer with the 4.10. Window sticker says 50 bucks. But you have to have Max Tow to get it.

Correct the 4.10's are $50.00 it is order code XL4. The only way to get 4.10's on an FX4 is to have ordered the 20 inch wheels $755 order code 642 and max tow package $565 order code 60P. In my situation I already wanted the wheels and max tow, so the gears only added $50.00.
