What do you guys recommend? My "plans" are to upgrade the rear axle (probably a Dana 60...or better), and upgrade the xfer case, and the trans to handle the torque, and it must be bulletproof (I DO NOT want any problems, I'll put in Rockwell's if I have too)....I haven't really thought about the front axle...yet, but any info would be appreciated (please help with this one too). The engine will be getting a Rousch supercharger upgrade, along with anything else that will/may be required...I'm looking for about 600hp and 750 ft/lbs of torque...or more (the more the better) at the tires. The engine it's self will be gone thought as well...of course. I am wanting to convert my truck to my own version of a "SVT RAPTOR". Please don't ask why...I just want it...BAD, with what I already have.

The truck still needs to be a fully functional 4x4. I am not opposed to NOS, or anything else you may come up with. Right now is the very very beginnings of my plans and I want to see what you think... Just imagine that you won the Lottery or came into a large sum of money, what would you do with it? I want a kick *** 4x4 that you can tear the sh*t out of and still drive on the street.

Think about it...Please...Imagine running it in the Baja 5000...and money is no object...

 

if it was my truck, money no object, i would get a custom made dynatrac 80 in the rear, built to take the abuse and torque from a diesel, i would call it bulletproof behind a 600 hp gasser. i'm not sure how bulletproof you can make the front ifs, but if i wanted bulletproof, i'd go dynatrac 80's front and rear, Atlas transfer case. for the trans, i haven't got a clue. but you wouldn't want a solid axle for racing, your gonna want a desert race-ready long travel kit.

 

 

 

FoMoCo - Now that's a beautiful truck!

That's a bit more than what I'm looking for though... $$$ wise at least. So maybe not Baja 5000, but one that I can 4x anywhere I want to go and over just about any terrain without breaking things.

 

theres only a couple companies out there that offer a LT IFS for the 04+ f150, i believe dixon bros racing is one of the few but they may be the ones that handle the 97-03 and that might be why they come to mind. which kind of wheeling you thinking of? would you want IFS or SAS?

i dont know what your plan is for the motor, to obtain 6 or 700 at the rear, but so far i've only had one good experience with a trans builder. Darrin Burch @ BC-Automotive.com has been an extremely helpful person with my bad experience with a local trans builder. My application isnt much different than yours, i dont plan on mudding with it so i took a higher stall. I have an engine that was built aiming for peaking a little over 500 fwhp and still being offroadable. if your smart, you can run a high hp motor and still pinch the pedal a little bit.

 

There's no such thing as a 100% bulletproof tranny with that kind of power!
You better put a 4R100 in it at least if you don't want a problem out of it.

sorry bud theres no 1 solution for what you are asking for. Theres good and bad things on everything.

ive seen broken 5 Tons ive seen broken 2.5 tons.

If you plan on runnin Rockwells your gonna want to run 44" or bigger tires. The gearing is 6.72:1 and the 2.5T's weight in around 850# a piece. I may have mis read that. The axles have a HUGE selection of aftermarket support but only have 1 gear ratio. The first thing you would have to do is add 4 wheel disk brakes, and new axle shafts 16 spline shafts are gonna last long. Another thing you will need is ALOT of lift for these to clear right, then you will need a divorced t-case and some other things. And still you arent bullet proof.

and there is no 100% bullet proof tranny. If you arent breaking something then you arent trying. With 600-700RWHP and 6.72:1 gearing you WILL be braking stuff.

Id honestly say build up a set of D60's chromoly axle shafts and lockers this will keep the weight and size down a bit.


Now to be reaslistic, get a set of d60's, set of bead locks. set it up with enough lift to clear 38's. 4 link on coilovers will work and look nice. This will work better than you migth think. and it will still be streetable. Pair that up with 4.56-5.13 gears and you would be in love.

My simple fact here is will you REALLY use this? Im SAS my truck but ive pretty much proven that i will used it and probably stil break it.

 

I agree with these gys that there is no such thing as a bulletproof transmission. The 4R7x series transmissions can handle a lot of abuse if built properly. The 4R100 series is stronger yet, but a LOT more expensive and will require putting a different computer in your truck or the use of an aftermarket transmission controller.

No matter what though, none can be made bulletproof. If anyone tells you that they can build one that way then they are less than truthful.

Since my original post, I have been doing a lot of searching on the net and have made a lot of phone calls. For the drive train, I think I have narrowed it down to Dana 60's with ARB lockers front and rear with 4-link, 5.56 r&p, a built 4R75, a built 5.4L with a Roush SC (but still looking into different turbo setups), Atlas 4 xfer case, and custom tuning by Bill at PHP...

I have looked into the 4R100, but that involves a lot of computer problems...


As my prodject gets moving along, I will keep everyone updated...

 

well good luck with the build, another good Tcase to consider is SCS they are good as well.

My build thread has started take a look. link in my sig.
