I have been searching for a new F150 and does anyone have an opinion which of these combinations would be better.
• 3.7 V6 with Limited Slip
or
• 5.0 V8 with standard axle
I am going to purchase a Supercab with 4wd and I do not plan on doing any towing, just hauling items from Lowes. My main goal is to get something which can get me to work during a snow storm.
Also, does anyone know why a limited-slip axle is not available with the V8?

 

I'm still waiting for my truck to arrive, so I can't reply based on experience, but I reply based on research I've conducted from other truck owners.

If you are mostly driving in snow and ice ON ROAD with 4x4, limited slip can be more treacherous because the back end can slide out on you. Personally, I think that a 4x4 w/o limited slip would be fine on a snowy road.

If you are mostly driving in snow and ice (or mud or whatever) OFF ROAD with 4x4, then limited slip can be useful.

 

For the 5.0 4x4 ford went with an open differential with an e-locker to used in conjunction with the RSC and traction control....

In my driving conditions it sounds like I do not lead the limited slip. I'm leaning towards the 5.0L STX.

Do you think that there is much difference between the 3.73 gears VS 3.55?

Thanks again!

 

If you are going to tow heavy loads or add larger tires then yes. If not then no.

Although this used to be true, with all of the traction & stability controls on these new trucks, it's no longer an issue. Without disabling anything, it's virtually impossible to get the back end to step out these days - in two or four wheel drive.

 

My vote goes to the 3.7L V6 & 3.73LS rear for your needs.

the difference from 3.55 to 3.73 basically amounts to around 150-200rpm on the highway. Highway mileage will suffer slightly & city mileage will not change.

 

The 3.7 needs the 3.73's to make up for its relatively low torque. That's why they are standard on 4wd.

 

Are those any good? I have a distrust of many of the newer electronics they put on vehicles lately. Hence why I bought a truck that has as few of them as possible.

 

you can't even notice it's open diff when driving. It's a very well thought out system that so far i've been very pleased with
