Hi All, I need a little advice, just got a 2001 ford f150 ext cab. with a 5.4L motor. GVWR 6300 lbs. I think it has the 3.31 rear end. it also has the full towing pkg. hitch,shocks,cooling,etc. lo...
I swapped my 3.55 to 4.10 ratio and it has been towing my 7880 GVWR trailer about everywhere just fine 12 years now. Click the truck in my signature for the towing guide. 2002 is same enough as 2001.
