Well I've been trying to get lots of opinions on the matter because I honestly have no idea what to do. I have an 08 F150 V6 manual and I absolutely love it, but it's not big enough! Many people have told me different things so I was wondering what ya'lls opinions would be. What I've heard the most was to do a pro comp 6" suspension lift with 305/70/17 wheels and 4.56. I guess my main question would be would this kill my torque and mpg or would this actually be a good option for my truck. I won't be hauling much, we have other trucks for our horse trailers, this truck was just gonna be my good college fun truck. I want it to be my fun truck but still be super reliable when driving across the country. If you have an suggestions, let me know!!
Thanks!

 

What color is your truck

 

The bigger tires will hurt mpg. I have doubts if a 6" lift would be necessary with that tire. But keep in mind that the higher the truck, the more aero drag it'll have and the higher the center of gravity will be. A higher cg will negatively affect handling and make it easier to roll over. I would probably go with no larger than 265/70x17's without a lift for the above mentioned reasons.

 

I agree with Greg that the tire size you want does not require a 6" lift. You should be able to get by with just a level kit. Also I would think that 4.56 gears would be too much, maybe 4.10 or 3.73s.



I'm also confused a house the color of the truck would change any of this.

I suggest the 305's and a level kit, and new rims to accommodate the width of the new tires. I think you will be happy with that combination

 

I think he was being a smart @$$ because OP is "cowgirl"

 

I was wondering what Color cause it can show a lot

 

I would say leveling kit or 4" lift kit. The 4.56's are a bit much for your truck and would hurt things more then help. I would increase the gears but 4.10's would be the highest I would go for your truck. The new gears would help with the loss in power and torque from the larger tires. Yes any lift is going to hurt MPG's some but how much is more a matter of how you drive. I have a 3" level on mine and barely noticed the drop in MPG's maybe 1 mpg lost since installing it.

 

Wait till you put the 295 trail grapplers on that thing coskid. That 1mpg drop will turn to 4 or more mpgs. Mine dropped all the way to 11.5 with them until I just recently put a programmer on it and it jumped back up to 15.5-16.

But to the OP, put level kit on and run the 265s and I too wouldn't increase the gears to more than 4:10. It won't tow a huge amount of weight, but will have enought power to not feel like a slouch on take off.

 

By no stretch of the imagination am I a gear head. But the fact that this truck is a 6 cylinder would probably limit the torque factor and mpg so much that new gears with the big tires wouldn't make much of a difference wouldn't it? Throw a lift on that thing and you throw a whole bunch of other factors in there that are going to decrease performance factors also. Unless you are just tryin to get it in the air and look cool. If that were the objective then I would say make it a pavement pounder that can get itself unstuck.

Otherwise I think if you would want to have some fun in it, long travel suspension on the rear end with a 265 tire on a 15" wheel with fiberglass fenders would be pretty damn functional and badass at the same time. That to me equals mega fun! You could pre run anything and probably out class any of your friends in the dirt. The regearing at that point wouldn't hurt either I wouldn't think. Im just a bolt on bum though, so nothing I just said may have any merit.

 

I agree cause u will lose performance, mpg, & torque but you could switch the engine to a 4.6L or a 5.4L then a 4.2L and since your truck is so light then you should get back more power and maybe a bigger gas tank should make more MPG, you could also add smaller gears then what you want, if you just want it to look cool like what Pugnasty is saying then you will lose HP, MPG, & Torque do to the Bigger Tires/Wheels, & Lift, i dont think those 4.56 gears will fit, like every one was saying that u need to go smaller but if you are going to get the lift and wheels then add some more power otherwise it will get smaller mpg then a smart car and go slower the a smart car

 

Ignore the last 2 posts, they are just throwing words out there


New gear ratio makes the engine and tranny perform closer to stock after adding larger tires. the motor and tranny will bog and stutter if it has low power, like this 6 cyl, and large tires. Taller gears compensate for that.

15"rims will NOT fit, don't even try.

 

this post and your post are the last 2 and you told us to ignore them lol

 

Dano, would u want to buy tan or any other color fenders that dont match your silver truck, she also said If you have an suggestions, let me know!!
so i was just looking for parts but need more info

 

It's a metallic red

 

Thanks, would you like black fender flares to match the big wheels
