Advantages to 4.56 gears
Hey guys, i am about to lift my 08 F150 with the rancho 4" lift and put 35s on it. I have heard that i should put 4.56 gears in it, how is this going to help my truck? (better mpg's?, faster?) and also what size are the gears? like in on my mustang it is 8.8 but i dont know what it is in my truck?
Thanks Guys!

Get the gears. They make a world of difference. Even with heavier wheels and tires u still will pickup a tad on the seat of the pants feel over stock setup. I had an 02 with 315 70 17s and the gears made the truck I thought. I towed a lot and it made a huge difference. I used yukon gears not sure what r best but those worked real well for me.good luck!

Yep, the heavier wheels and tires will burden the engine and trans as they require more HP to spin up to speed just like bigger heavier flywheels so the gears will help as they simply multiply torque and 4.56 is a bigger multiplier than 3.55 or 3.73. Of course, it all will require more gas per mile which is less miles per gallon, and then you'll have to stop all that rolling mass which means you can look forwards to spending more quality time with your brakes.
Sounds like a fun package ....

I just do normal street driving, no off-roading. and i havnt and dont real plan on towing anything seeing is that i dont have anything to tow. so in the end the the mpgs will drop and my brakes will wear out faster? sounds awsome!! lol. But hey if i am going to lift the truck i guess i have to deal with it.

If you do the tires first, you'll see a good drop in mileage and increased brake wear and the trans wil work very hard and the truck will be like a dog.
If you then do the gears, you'll recoup some of the mileage and acceleration and your trans will thank you ... but not all as you are still doing more work moving the same truck and heavier wheel and tire packages even if gears return overall ratio.
You'll still wear the brakes more.
Nothing is free. With something, there is always a cost. I bought a $6 magazine tonight, didn't have to have it, but I wanted it.
I'm talking "real" miles per gallons, not those indicated by an incorrect odometer.
