What is the best type of differential for towing?

I have a 2009 ford f-150 4x2 5.4 v8 regular cab with an 8' box. I have the max trailer tow package and I will be towing a 10,000lb+ boat with it. What is the best type of diff. for towing up slippery boat ramps? I am pretty sure it comes stock with a limited slip diff. Should I stick with the stock diff. or have a locking diff. put in?What is the best type of differential for towing?
Selling your POS Ford for a mans truck=Dodge



Our company stopped buying Ford trucks because all of the mechanical issues. We continue to buy Dodges and GMs because they last long and have great torque.What is the best type of differential for towing?
the stock differential is fine but steeper gears will make it easier. try 4.56's or higherWhat is the best type of differential for towing?
Look at the window sticker or ask the dealer to look up what diff you have. I haven't seen it yet, but have heard of the "one wheel peel" as the boat drags the whole works in to the water.



A limited slip would be OK, until it wore out.



On open diff, most times would be OK. Just don't turn until on flat ground, it will became the one wheel peel.



Locking diff= nothing could be done if it ends up in the water.



What does Ford say for max trailer weight?



I had a 2001 1/2 ton Chevy 4x4. It had a LOCKING diff in it from the factory, part of the snow plow prep package, which also was max trailer package. It rode rough,when empty. It had extra heavy springs / axles with 3.73 gears. It only locked at, something like, under 15 MPH. I was (low 4WD) pulling a 23' cabin cruiser up the ramp. At the one ramp, I was 2 or 3 blocks away, before shifting back to 2WD. Never towed it more than 8 miles at 35MPH, which was scary enough. Bumper was a low to the ground (overloaded). About half of normal height. Boat weighed a bit / quite a bit more than my tractor, 7,500 plus trailer.Tractor once went 25 miles at 45 MPH on open roads. With electric, double axle brakes, easily DOUBLE stopping distance. I did this at 25K miles. I had to put the brake to the floor, both feet, twice to stop; the brake controller would be manually maxed out. Without the tractor, the controller instantly locked the brakes,just touching the brake pedal.That was with extra stopping distance, way "before the stop ahead sign" (500'). Hauled tractor one trip, both ways, 25 miles. Boat once 8 miles one way, twice 6 miles both ways. Front brakes made 42K miles %26amp; back made 50K miles. In Tow / Haul mode, the 4.8 motor would be screaming (5-6,000RPM) before shift. Computer was taking engine to red line.



10,000 + equals at LEAST 3/4 ton truck with trailer package AND weight distributing hitch. I wouldn't tow this any real distance / too many times without a 1 ton truck!



As in, are you bleeping nuts, with a 2WD half ton?!
