I have a 2005 FX4 F150 5.4 Triten and have lifted the front 2 inchs, i have put on goodyear 35's on fuel rims. Also have added a k&n cold air kit plus a edge programer. I would like to get more pulling power, would changing the stock gears to 4:10 be worth it. I do pull trailor with 2 4-wheelers on it and am thinking of getting a 7 thousand pound toy hauler. Any idea would be a great help. Thanks

 

You have 35's so going to 4.56 would help. 4.10s wouldn't do much. Your stock gear ratio I believe is 3.73 right now.

 

Thanks alot, big help.

 

Do you think the 4:56 upgrade would be enough to handle the toy hauler at 7 thousand pound using bumper pull not 5th wheel?
