towing specifications ford F150 4x4 4.9liter 5 speed manual trans
5,000 lbs. with proper hitch.
In accordance to my owners manual for my 90 F150 Axle code 12, 18 and 19 is 3800 pounds Gear ratios 3.08 and 3.55 Axle code 25 5300 pounds. Gear ratio is 4.10 you can find the axle code inside the drivers side door jam where the vin sticker is.
If you got a B-W you have better towing capacity if you got an M trans you got lower capacity and torque but generally better all -around
