Hey, I gotta 97 F150 XLT Reg Cab 4.6L, I am wondering if it will be enough to turn 35-38"s in a mud hole. Or if it would with some upgrades.

 

im sure in the mud it would... get 4.56's and/or a supercharger

 

id hit 4.88s if u want to be able to do anything like that in stock form and over 35"

im locked all 4 and theres times the lil motor cant spin them in the muck.

 

Definitely 4.56's or higher.....

Nice picture Klitch!

 

YEah some good ole gears will turn those wheels for ya. Something like some 4.56s would be a good choice. If you really want the extra torque the super charger isnt a bad idea eighther!!

 

Assuming that you had the 255s as stock you are going from a 30 inch tire to a 35 inch. It is like re-gearing to a 3.05:1 gear with the 255s. A 38 inch tire will be like going to a 2.81:1 gear. With the 38s you would need a 4.56:1 gear just to bring the gear ratio back to a stock number equivalent. So even with the 4.56 gears you have not yet compensated for the extra weight of the larger tires.
Gears are a top priority. Once you have done the gears you are only barely back to stock so some engine mods will be required. You had better also look into upgrading the transmission. I would also at the very least put a girdle on the little 8.8 rear differential. The next thing to remember is the CV joints. They do not like to turn large tires. Specially when the wheels are sharply turned. They tend to come apart. I run 33s just for that reason.

4.88 gears are the way to go.

 

i have a 4.6L im my truck and plan on running 38.5" tires very soon. my math says that i need at least a 4.60 gear to be the same as stock so im just going with 5.13 itll be more then enought to compensate for the extra weight and hight of the tires. and the rpms at 85mph will only be 300 higher then if i went with 4.88's

dont fear the gear!

 

Klitch, you know , every time I search google images for an f150 part, illustration or anything using this type - "F150".. -your pic always shows up.

Your a celebrity dude and you prolly didn't even know it.

 

LOL your too kind, i aint seen myself yet!

 

I ment your truck

 

hah oh lol. well still i didnt see my sexy beast. man its getting a brutal tear down. all these f'n wire connectors are so brittle already. btw, i asked JMC 97 4.6 has a single wire splittin off the bundle for the L coil pack and cam sensor that runs down the block and dissappears in my oily muck by the filter... think u can find it on alldata? lol

 

I have a new 4six harness that I stripped COP harness out of - The guy thru it in the deal when I purchased those type 3 injectors - hell , $60 for new injectors and harness - I couldn't pass it up. That's all I used from it tho - lots of connectors left if you need some.

Left Coil Pack = Passenger side pack - BTW - I'm not with ALLData anymore, I'm surprised you didn't notice - But, I can get the info for yuh. 97 harness correct ? Did you look in my illustrations gallery ? You need better pics of the split ?
