Ok first off im just the engine builder not the truck owner, but i told the guy i would find as much info on his truck build as i could, so here it go's....the truck is a '89 F-350 he plans on setting it on a set of 52" tires and mainly will be using it in mudbogs and such. The truck wont be seeing very little rockcrawling if any ( not many rocks in this part of the country) so mud is the game around here. Ive been looking at the 4-link rear suspension from Polyperformance and was wondering has any one used it and what they used for the front suspension and what shocks were used? I also need a little info on the front and rear axles used in the '89 F-350, are the front and rear both Dana 60's? Thanks for any info you can give!

Since the plan is to use 52's on a fullsize and mudbogging, I hope your planning on a mill in the 800hp/tq range and using massively upgraded rockwell axles or their equivelent. Unless its just a mall cruiser. A build like this can turn into a steaming pile of fecal abortion quick unless the dood knows what the hell he's doing. You're on the right path with the four link, even though its not super necessary for a mudbogger.

the axles under his rig currently should be a dana 60 front and a 10.25 sterling rear axle. But like Pro said he had better get some big power numbers and some stout axles.

This guy is very serious about the truck build. First thing i did was to send him searching for a Dana 70 rear, seeing that there is no gear or locker selection for the sterling axle. The engine hes using is a stroked 460 to 533ci made around 650tq on pump gas with ported Dove heads and 2.19 and 1.73 valves installed. His plans are to upgrade to a set of after market heads but that will be after the truck build is completed.

i know that 52's are big, but i believe that those axles *should* hold up in mud. put good shafts in the front and i'd think it would hold. im not bashing, but theres probably better sites to get more info on the mud side of things than pirate

ya Know any good mud sites?

I've got a feeling this is a lost cause, but here goes.

First of all, your not going to find better tech than on here, mud or otherwise.

Furthermore, when you are talking running 52" tires mudbogging and the necessary horsepower to spin those tires while buried, one ton axles are NOT up to par. Period. Stock one tons can't even handle 44's in those conditions, and I know a little something about that. Sure, you can go chromoly axles and ctm's (like I did), but they won't handle what your customer wants to do. Even rockwells would have to be upgraded. Talk to Dibble if you don't believe me, he couldn't keep rocks alive with just 44s and a mild engine. U1300s would be up to snuff but I've got a feeling that might be too exotic for this particular build. Search on here, all the info you could ever want for this has been covered. Good luck.

I dont know if a 70 would hold up. Depending on the motor obviously, but strength wise its similar to the Sterling in his truck now. 2.5 tons are your best bet for sure.

Might be a little exotic (F550 and up, most new Ford motorhomes), but I wonder if a Dana 135 or 150 would hold up? They are behind some diesels with massive ammounts of torque

whatever those are ,they have rockwell 2 1/2 ton outers welded to them

here's a good website for you to look at, check out the message boards. These guys build trucks specifically for mud drags. 600+hp rigs, running dana 44's up front on cut boggers. Mud won't brake those axles, but don't plan on using it for anything else.

Here in Louisiana, mud is about the only thing that we see. That being said, I know of a couple guys bashing stock 60's with 49's regularly with between 400 and 500 hp. I know one guy running a buggy with 52's and stock 1-ton with about 400hp. Mud is know were near as abusive as rocks, therefore u can run much bigger tires with less axles. I really think that rockwells will be your best bet though for this big heavy ford to not have any breakage. Not only for their strength, but the amount of lift u will need to clear 52's will probably make it extremely hard to get a front drive shaft to work without the rockwells. It is worth a shot if u or the owner is dead set on running the stock axles, but for the money he could get for the front 60 alone could buy a complete set of rocks.

Steve built those I think, 5 ton outers on D70 centers.

Looks more like D80 with 2.5 ton outers, cool as shit either way and a good option instead of the big toploader diff.

what state you in i have rockwells! im assuming you are in mid-east, im in california

I compete in both, and I assure you that mud drags and mud bogs are two entirely different animals. You can get away with lighter axles in mud drags as you are dealing with comparitively shallow mud. This guy wants a truck for mudbogging. In that case, if he wants a serious truck, it will need axles that will survive 52's buried in mud, along with the added weight of the mud to an already massively heavy tire, as he's sawing the tires back and forth to make it through the bog. One tons won't cut it. He will also need the horsepower to spin said tires while buried. I'm pushing over 600hp and I barely have enough power to make my 44's work properly in deep mud, which is why I threw out my original horsepower figures that he would need.

Granted, all my advice is if the guy wants something that won't break the first time out in a real mudbog and be able to pull through whatever he wants. He can go with the lighter axles and build a lower hp motor if he wants to just break stuff and get stuck before he figures it all out......which is what the rest of us had to do before we had the internet with all this experience and knowledge a couple mouseclicks away. Good luck.

I will agree, building the one tons is a waste of time & money, the weight & mass of tire you are going to be dealing with will murder the 60 shafts, the other thing that nobody has mensioned is the fact that even a king pin 60 will suffer from that size tire, the knuckle on a rockwell would be much better suited to your needs,

I am currently pushing 1500 hp to a set of 44" boggers with chromo 60 axles longfield 300M joints & after market axles in the rear, they seem to be holding up so far, however, would I bolt a set of 52" tires on my truck? nope, I feel they would be the end of the shafts I am currently running,
