Hello Ford truck fans! I've always visited this website, I've just never made an account. I was looking at my truck today, and I want to see how big I can make it. So, I figured I would make an account and ask a couple of questions about making my truck twice the size it is now. Currently, I have a single cab, long bed F-150 with a 4" Rough Country suspension lift with a 2 inch block under the coil springs with 33" tires. It has a stock 302 with 218k miles, but thankfully I have a 351 sitting in the garage that I completely rebuilt from the ground up .. headers, cold-air intake, you name it. It's ready to put in, and it's going to be done soon. Now to the point ; I could clear 35's in the front and rear easy as the truck sits minus possibly having to move front the bumper up a little bit. My goal is 38" (any suggestions for an aggressive tire) tires. Rough Country suspension lift has the brackets for the IFS axle to where I can adjust from either the 6", or 4" suspension. For the front, I was going to set the brackets for the 6", get 6" lift coil springs, plus the 2" blocks, I would have 8 inches of lift in the front. Now for the rear .. I have an add-a-leaf that should add 2 inches to the rear. Would I be able to clear 38's with 8" in the front and 6" in the back, or would something else have to be done. I apologize for the story book, but I really appreciate any replies. Thanks in advance!

 

I think you could with the right wheel and tire combo!

But more importantly...I'm hoping you have plans to swap in axle gears and beef up your transmission!?!
Your also going to be replacing steering components like crazy!
I'm not trying to sway you from running this big of a tire! You just need to take the right steps to make it right!

 

Yes 4.11 front and rear should do the trick I believe. The transmission has already been beefed up a little bit. I'm sticking to the Mickey Thompson Classic II 15x10, it's just I'm having trouble finding a tire from the 37" to 38" range that has great life, performance, and fairly priced.

 

Your going to want to regear to 4.88 with a 38" tire! 4.10 are good for 35" tires. If you do run a 37" tire you could go with 4.56 gears and be ok as well.

Try dick cepek FC 2 tires. They have a deep tread like a mud terrain but the lugs are closer together to keep them from heating up on pavement like a m/t tire and wearing out. I had a set of 37s on my superduty and they lasted 3 times as long as my Toyo opencountry m/ts I had before them!!
I'm also running a new set of falken wild peak A/Ts right now and there amazing!!! I would buy these tires again that's for sure!!

 

To be honest with you, I've been doing more and more research and I would save a lot more money, and my blood pressure to just run the 35s with 4.10s and call it good. Thanks anyway bud I appreciate it

 

There ya go! Thats a better idea!
These trucks support 35s great and your front end will thank you for it!
Check out the tires I mentioned tho! If you want something that performs like a m/t but lasts like an A/T there a great choice!!

 

Not to change your mind. Heres my planned suspension setup


8" skyjacker drop brackets.
4" coil spacer
5.5" superflex coils(broncograveyard)
Camber bushings.

So thats 9.5" up front pure suspension

Now rear.
6" superflex leafs
6 degree tapered 1" block to help driveline angle

Front: 9.5"
Rear: 7"

Add in a 1" hockey puck lift im doing.


Or, if you wanted go to a 2-3" body lift. With that setup, and a 3" body lift, you shouldnt have any problem running 40's.

 

Wes, one thing id change about your plan is the 6 degree block. From what I've read tehy don't work that well and are hard to keep centered. If it were me, id do the extra work and weld on new blocks at the correct angle

 

How would i go about doing that?? Wouldnt the u-bolts help keep them aligned?? They have a center pin

 

I don't have any experience with them myself, but I've read more bad than good about them
