First of all I know the rockwell's have a 6.72-1 ratio. Problem is I have seen to many mud trucks with these and they all seem geared to low. Let say you have a 35" tie with a 3.73-1 axle ratio and you wanted to keep the truck around that area in the way of gearing. What size tire would you need with a 6.72 to make it equivalent with 35s and 3.73?

Second one is, What do mot guys use for a drop down T case that has 1 input on top then dual center out puts dropped straight down? Kind of like a monster truck, but on a smaller scale. Thanks.

If you just wanted straight up equivalent, a 63" tire would put you at the exact same ratio that you have right now. Considering the added weight of the tires and rims, and the rotational mass of the axles themselves, anything in the 44"-53" should work out about right.

I would index the t-case before I would do a drop on it. How much lift are you planning on running? Remember that rockwells are top-loaders, so this will help to improve you driveshaft angles.


hick

Thanks for the reply Hick. I am looking for a good foot to 18 inches. This is a comp mud truck so I dont need to worry about being to tall. I agree that 63s may be a bit tall, but I dont to want the engine bouncing off the 8400RPM rev limiter and not have the tires spinning fast enough to do anything. I dont want to use the stock T case cause its weak. And I want center out puts. I wached my new trucks gone wild video for ideas and a lot of them have rocks, tractor tires and drop center/center T casses. I looked at the extenda boom fork lift at work from Cat and it had a nice one, but I am not sure where to find a used part like that....

Thanks again.

i feel bad for you. :(


WTF do you mean?

Why does a mud truck have to be tall?

My mud truck is low. Around here, we had allot of of the mile high trucks rolling in the bogs, so they've started coming down.

Get either a NP200 M35A2 t-case, or get a SCS T-case.

Any divorce mount t-case will work, but the Center Mount drop cases are going to be from a company like SCS.

Alot of your mudtrucks are running between 44" and 57" tractor tires. Alot of the 1500hp+ trucks running the 63" rice and canes but most are happy with smaller tires.

chuckstrucks.net is a place you should head to and get on their forums and ask the questions there.

This should be an ANGRY truck.

WTF do you mean?

We are not allowed to ask mud truck questions on this site because it is a "hard core rock crawling site":stirthepot::D

An SCS or Pro Fab style t-case is your best bet, remember with these t-cases you can pick your gearing, this would allow you to gear for whatever wheel speed you want/need.

Mud trucks aren't real welcome around here, most people are into rocks and stuff, I wonder if a mud forum would be popular? If nothing else it would keep the big gehy trucks in one spot, kinda like the hummer forum:laughing::laughing:


Brewchief:D

Where would I find a SCS or profab T case info? I joined chucks trucks and looked at there M37 T casses. I dont want to spend 2 or 3 K on a T case. I want something simple with preferbly a 1-1 gear ratio so I dont have to worry about gearing and all. As posted above if I run in the 50s for tire size I will come out in the neibor hood I want. There happens to be such a thing as 54" Boggers!!! That sounds good to me.. I would like to gain info. I need to learn more about the M37 casses and see if they will work. Also sounds like I should run 5 ton rocks nstead of 2.5 but would try either one I could find. Thanks for all the info for those of you have helped. A truck is a truck.

Unless your are going to be running at least 1000+hp and 60+" tire you don't need the 5 tons. www.ouversonengineering.com will have all the products you need to make your 2.5 tons work.

If you plan to drive the truck on the street you need to run wheel brakes. Its not the safest way to go to run pinion brakes on the street. At the bare min you need wheel brakes on the front axle. The site above has some great brake options.

Here is a cheaper DIY brake option http://www.pirate4x4.com/forum/showthread.php?t=408046&referrerid=43190]

the more you can throw the mud up and out of the way of the tires the better (the tires clean better as the mud isn't droping back on the tire or collecting up underneath the truck), and also to get the frame/belly up out of the mud, which is needed with the deep mud.

I have never had a problem with mud dropping back onto my tires. That's the dumbest thing I've ever heard.

The frame dragging is feasible, but only two of our competitions have mud that deep, and I've still never had a problem with getting hung up on my frame.

Yeah, I have played in some pretty deep goo and never hung my frame... axles and diffs... all the time, but I am only on 40's... My diffs are my down fall.:shaking:

Why would you want to have 3.73 with 35," your loosing a hell of a lot of power and making your truck inefficent. I have 4.56 on my 35" and my mud truck is also a dd - if your gonna gear it find the tire size you want then match them with the gears that give you optimum preformance - not the other way around. Good luck with your build mate

i think your better off with going 1 tons, and a healthy big block, with about 8" lift and 44's. duces are cool, but if your mud bogging/ racing, theyre really heavy. ive got a tall truck and i wish it was smaller, but im not buying different springs so it stays:flipoff2:. ive got a toyota were working on with 1/2 tons and a 560+ hp small block, 1/2 tons for weight and ground clearence. just my opinion but big axles arent the way to go in the mud, its horse power and tire speed

I think probaly 90% of the people here started out in the mud.

Although I know you're talking about your experiences in San Francisco and the "alternative lifestyle"; I can't disagree in that most of us starting wheeling mudboggers :flipoff2:

I still love rocking the pits, but hitting the trails/rocks is indeed nice because you don't have to spend half the day cleaning that shit up. Then again, thats what your shotgun bitch is for :D

I live no where near san fran, but the whole state of VT is just like it :laughing:

It only takes about 20 mins to clean up my yota. I imagine my crew cab will be alot more work to clean tho. Be looking for a build thread starting right after the new years. Preliminary tidbits: Rockwells, 4-link, 460/t18, divorced 205, 53s for rocks, combine tires for the goey stuff.

Go with the M37 case(NP200), built u a cradle like they use at Chucks trucks, real simple. I mounted one in my buddy's truck. U may want to do some more searching about using a 1to1 ratio(high range). In this same truck, he is runnig rocks with 54's and a fresh 496 BBC with a little over 900 HP, over 1000 HP on the bottle. He can run high range second gear(TH400) in short runs, but the tranny heats up real fast. 2nd and 3rd gear in low range, no tranny heat and plenty of wheel speed around 6500 to 7500 RPM's. If u watched some mud truck's with rocks that lacked wheel speed, it was because they lacked the power to reach the appropriate gear for the wheel speed. I know, I have that problem:flipoff2:

Now is the M37 a D200 then? I havent herd much good about them... Are they a 1-1 ratio? How do you like the 53? Cant decide if I like that idea or the 54 boggers... Is there I high and low like say an Np205 in the D200-M37?

D200?? not sure about that. THe M-37 case is an Np200 with both front and rear outputs offset. I has a normal high range(1 to 1) and the average gear driven low range(1.96 to 1) It is very similar to a Np205, I think an earlyier version. THe 205 has a little higher torque rating, but many people running the 200's with high horsepower and no problems. Obviously, any body would prefer the 54's over the 53's, except I bought all four of my 53's for the price of 1 54":D

I felt stupid just reading all my mispelling:homer:

The best/fastest mud truck I've seen was an FJ-40 that only had enough lift/cutting to clear the 36" paddles in the rear, the fenders were only a couple inches off the tires. He was also running basically a drag motor, but he through down a run through the pit in under 10 seconds. In the same pit, an F-250 on 49's had to sit and churn to get through. Big power and light will be better than a big lift and heavy axles.

paddles/rails are a completely different animal, and 10seconds with paddles assuming he had the stupid power they need is slow, he should be in the 3-6 second range (for a 200ft long pit) :flipoff2:

BIg differance between mud dragging and mud bogging.

Why use such large tires? Isn't wheel speed the key in mud bogs? I would think that transfer case gearing would be the key for wheel speed and rockwell axles.. Look at Dan Dibbles old ride.. Big block motor, rockwell axles, Atlas 3.0, and 44" boggers.. He had all the wheel speed he could stand.. Granted its not a 1000hp motor, but the theory is still the same.. Transfer case gearing!

Well let me add a couple things then. I don't have any mud around here that I cant handle now with like a 38" tire or so. I just want to build a BIG FORD truck. I have always wanted one. Most of its run time will more than likely be on the street. Now I realize that for the street my 1 tons would probably be fine with 53s, However I didn't want to buy expensive gears and still have weak axles. Not only do I want ti bit, I want it to look cool and not break down when I want to race some dumb punk in a ice burner and I lay out all 700 horse at once. So....The Rocks and probably the 53s are the way to go. The only thing I am unsure of is the T case to use.

RED CHEVY, I did mean NP200 not Dana200 sorry. I will have to look up the np200 for more info. I assume its a divorced set up? If so, does it have a drop with center out puts for the front and rear dl? Or is it offset like a traditional 205 or 208 or something?

Wheel speed means fawk all in bogs (paddles and 700+hp is different) if you don't have enough clearence to keep the axles and frame out of the mud, ideally you run the biggest tire you can run without powering out. In terms of gearing, well more gearing just helps you get to to same max tire speed as what less gearing will, it just gets there faster, the top speed will still be the same.


This was a mud bog, they drug more trucks out of that pit than made it on their own.

paddles and high hp don't care how deep the mud is, the idea is to skim accross the top, hell most of them will skim across water. Everyother bog i go to none of the trucks make it through, and the big guys are running 600+hp and 44's don't even come close, whereas the rails are having to slow down so they don't catch any air coming out of the other side of the pitt.

Ford Trucks, from what I have read about the 200, if it is going to see a lot of street time they tend to have heating issues. As for as the offset, originally they are a passenger side t-case with front and rear outputs on the passenger side. Build your own cradle with 6"x3/4" flat bar like chucks trucks and rotate the outputs straight down like u want. We mounted my buddies up and to the left some cause he was running his rockwell on the ford side and was too hard headed to just rotate the axle around to the chevy side. It works fine like this, just a little more trouble running linkage, of course it doesn't see any street time either.

I don't suppose you could get any pics of this set up could you sometime? As for cooling I suppose you could tap 2 fitting into the bottom of the housing and use an electric pump to circulate the oil through a cooler to solve that problem ae?

Thank for the help man. Seems like your about the only one here who is decent..

This is from chuckstrucks.net , this photo is from the front in a passenger drop setup. this is exactly how we did my buddy's, real simple.

Are you sure about that? That cradle would be heavy! I know the Np200's and m-37 cases are darn heavy and need some beef but dang...

Seems easy enough. Now if only I can find a NP200 I will be golden. What did they come in? How does the linkage work mount up and work out on these?

And I still have not recieved a definate answer on this yet.. IS THE M37 T CASE A NP200?

This thread is fucking stupid. You want to build an uber mud truck, but you don't know what tires you want, what axles you want, what gear ratio you want, or any fucking thing else. All you've said for sure was that you want a Big Ford.

Well, Whoopdeefuckindoo. Do your homework and make up your mind.

By doing your homework, I mean searching, looking at different options, deciding how plausible they are, with your obvious lack of knowledge, and then give it your best shot. What I don't mean is coming on here asking questions, and then every time someone says something, you say, yeah... yeah.... that's what I want. You don't have the foggiest fucking clue what an M37, M715, or NP200 is. You have never seen one, and you are just repeating everything you have heard.


Grow up, search for your self, and then build what you want.

Hell, I can come on here bragging about what I'm going to build, or what I want to build, but it doesn't mean a fucking thing till I start building.

A word of advise. Every build is a compromise, so figure out what is important to you, and then build accordingly. First thing you need to do is learn how to operate a fucking calculator, so you can avoid showing your ignorance with stupid gear ratio questions.

Since your a new member here i will forgive you and your dumbness. I know a lot more about building a truck than you may think. However I sure don't know it all. That is why I ask a few questions. Unfortunately I have to deal with mean ignorant folks like you self. I know exactly what I want. I just need a little info like on the T case I needed. Thanks for you input but I don't need input like you just posted.

Is your dick the size of a breakfeat sausage or something? I mean "I want a BIG FORD". Great, go get yourself a d30 front, 8.8 rear and run your 53's with 40" of lift. No one here cares about it. Why the fuck people are still trying to help your dumbass I'll never fucking know.

Yes the 200 is the M-37. M-37 is the military truck the NP200 was run in, I think it was a dodge.

Yes the cradle will be a little heavy and overkill, but a full bodied, full size truck with 53's...... not really gonna see much weight difference:D.

These guys have a good point man, just spend some time looking around on the net, google is the best tool invented for the internet. You can find all of what u are asking and some u haven't thought of asking.
