eh... i'll play.

my mud truck....
18.4-30 R2's/5 Tons/Stock/4L80e/4 Link/hydraulic ........ not finished, so i havent broken anything. :D

my jeep...
39.5 boggers/1 tons/none/SM465/stock YJ/XJ combo/hydro-assist .... haven't broken anything except 14 bolt u-joint straps

my old mud truck was...

14.9-24 R1's/2.5 tons/3500rpm/th400/4 link/hydraulic ..... it didn't break anything either.

Imagine that, the FL mud guy & the PNW mud guy hangin' it out for the crowd. Spent some time on Chucks trucks forum, you guys are wackier, more redneck than us!! Those trucks w/72" tractor tires & 1500 HP are awe inspiring!!! One of those trucks might make it thru our "TankTrap". We stuck a Cat 235 Excav all the way to cab in trap for Hangover 09'. Show us some pics please!?:smokin:

Heres a question I'm been pondering. When doing a 4-link (yes I have searched and read alot and still reading the rest) what version of 4 link are you using? I see alot of rigs running lower links parallel and to the frame while the uppers are triangulating from the axle center to the frame. I see this mostly on the supper tall rigs running ag tires though. Having just got back from Kuwait I'm researching all I can before begining to sling my rocks under my 79 f150.

83King...I campaigned the 1/2 ton F-trucks for 3 decades & am quite familiar with the shortcomings. Finally went to tons on the Big Green Hunka'Junk. Much happier:DLess Drama:eek:. Get rid of that half ton stuff or downgrade tires, yer' gear ratio's high as well. Being locked up@lower gear ratio w/ heavier axles increases the fun factor by a bazillion!!! Keep floggin yer' FOMOCO brother!:laughing:

...i keep breaking the secter shafts off the steering boxes.

Sounds like you need to run some type of Hydraulic assist on your steering. The hydraulic cylinder will take some load off your steering gear, and most likely prevent the failures you're seeing. Either that or it's time for full-hydraulic steering on that rig...

That was my plan, but finding a th400 4wd was almost impossible at the time in my area. So i got a turbo 350 built to hold some HP. Been running strong for almost 2yrs................:smokin:

I'd have to see your front driveshaft angle and know what the fracture looked like. I'm thinking it was caused by a bind, but that's just a guess without knowing more about your set-up.

Since you already have a 32 spline out-put it has to be binding. Are you running a 1350 yoke or a 1410?

Stock 60/10.25/T19/1345 in my junk, haven't broken anything yet... But I'm running little tires(38.5 skinnies) and no real serious HP, an 8.0:1 460 does not big hp make...

Pro, that a single or dual disc McLeod clutch you're running? I've been kicking around the idea of going with one of those so I can keep my T19, I haven't been able to find a decent clutch that will take a launch with any sort of rpm in high range. 1500 seems to be about the max I can pull off without clutch smoke if I dump it. I know gears lower than 4.10's would help, but, if I could pull off a 3rd high launch I wouldn't need to worry about shifting in the 250 foot pit... Right now even in 2nd I have to get the clutch engaged before 1500, then hammer on it.

d44 heavy duty with 27 spline axles and it was a kingpin style it also had hydro assist steering from the factory.

now i got the same truck with 2.5 ton rocks its gonne have 46 american farmers 203-205 doubler and a 460 mildy built. i was thinking about 4link but to much money and not enough know how or a place to build it i wish i had pics but dont:homer::flipoff2::evi

We should have something going for the guys doing strictly comps and one just for fun

i run an 80 f-250, front axle pushed 12 inches ahead, d60 front sterling 10.25 rear, 4.10 gears and locrights, running a 205 and np 435, then a worked over 408m, pushing about 450hp, kept the cam on the mild side to still pull an ok vaccuum at idle (i've ran into a few places that require pulling a certain vacuum at idle in the class i race in, but it'll still rev and live at 7000rpm with power all the way there :) , that said i'm running 4v quench heads that have been taken to the max porting wise, zero deck pistons with about 11:1 CR, comp cams 275deh, fully balanced and all the things to go with it all.

Yep. and axles, and pretty much anything driveline related. ahem=
step 1- gears! your running 3.50 gears!
step 2- disreguard step 1 and upgrade in axles to at least a 1 ton rear with 4.88 or 5.13 gears and re gear the front to match.

an easy rear is a ford 10.25 / 10.50 from an f250/350 late 80's to late 90's. Easy to find 4.10 geared ones. That is what i had and all my buddies run that same rear end.

actualy your gearing can make a huge dif and those tires put alot of stress on shit it takes more torque to turn your tires with the gears you have so more stress on everything in between would go with at lease 3/4 ton running gear cause it would be easy to get then get a 1 ton front end later but you def need to upgrade axles

Yep. The 3.50 gears you are running is putting tremendous stress on your drivetrain, Increase the gear ratio and relieve a lot of strain. Trust me. And now 6k RPM dumps on the clutch, well there is no bulletproofing for shock load.

And an example of the gearing problem- you ever tried to climb up on a car or rock or something? Did you make it?

i wanna put some 3/4 ton axles under it (12bolt/D44).

i dont do mud racing or huge mud bogs, mostly trail rides and mudidng on private property.

the 3/4 ton will be for 38s or 40s if and when i get to that point.

I'm extremely proud of myself for catching this question :D

Its the single disc McLeoud, advertised as a "race" clutch with a "harsh" engagement. Its their most aggressive clutch, but personally, I don't find it harsh at all and it hasn't slipped, not even once; which says one hell of alot considering the load I put on it. I did have my flywheel drilled for the bigger clutch, which makes a huge difference just by itself with the larger contact area. Granted, I try not to shift when I'm spinning in the slop and would risk getting crap between the flywheel and the disk, but still, I'd recommend this brand to anybody. Personally, with my gears I favor third low for racing, but we only have 200' tracks out here.

01-21-2009, 06:29 PM
Hmm, sounds like a winner for sure, I may have to give it a shot.
Last summer my first run out with the truck with the tires, SAS and 4.10's was on a 200 foot track, I found myself still needing 4th low(works out about midway between 2 and 3 high) or doing the 2-3 high shift to try and keep the bottom end in the thing, mind you that is a fast track and not very deep, first run out on fresh dang near everything and I was running in the low 9's letting out at around 3/4 track as the exit on that particular one is pretty much 3 feet straight up and guarantees airtime, with how my pile is sprung in the front, I valued not bouncing my head off the roof alot more than going fast.
Unfortunately I didn't get to run the 250 foot track I normally do, If I had of taken it there, I'm pretty sure I would have lost the bottom end, as it is just trail riding it barely made the summer without killing itself.

Proeliator
01-21-2009, 06:33 PM
Yup, its a fine balance between torque, horsepower, and gear.

Third low works well for my combo, at least in a 200' pit.

most carnage/broken parts in this version of the trucks life:

dana 44 yukon stub shaft, ripped the ears off, blew the ends of the ujoint caps off, didnt hurt the inner. done while pushing a vertical wall in a mudhole, only that tire had traction.

9 inch rear, broke the right side axle shaft while doing a donut and the right side tire got traction in a bank... broke the shaft, spread the spool carrier bearing enough to split the inner bearing race, broke the diff carrier bearing cap right off.

cut boggers dont have much in the way of lateral traction, so sidehilling isnt a lot of fun, just mash the throttle and point uphill.

eh... i'll play.

my mud truck....
18.4-30 R2's/5 Tons/Stock/4L80e/4 Link/hydraulic ........ not finished, so i havent broken anything. :D


i guess i could update this.... that setup broke a 1610 u-joint, but that was it.

the current setup is...
30.5-32 R2's - planetary/2.5 ton hybrid axles - stock 6.0 and 4L80 still. i haven't broken anything with this....

i'm thinking about swapping to a cummins and 545 allison transmission.

How about some tech??? What are ya' runnin?? Tires/Axles/TC/Trans/suspension/steering..........What are ya' breakin?

Not extreme like the majority of yall :flipoff2:

-37x13.50" Pro Comp Xtreme All-Terrains (temporary)
-2006 Dana 60 front, 35 spline inner & outer stock shafts with 4.88's & Detroit Locker/ 2001 Sterling 10.5 35 spline stock shafts with 4.88's & Detroit Locker
-Stock chain drive Toyota Tundra case
-Stock A340F
-Radius arm front w/ 12" FOA coil-overs; full leaf spring rear with Pro Comp ES3000 shocks
-Standard mechanical steering w/ hydro assist

Never broke anything on the axles (even when I had the Dana 50 front). Blew out 1 stock chain drive t-case and 2 Inchworm reduction boxes when I had them installed.

I suppose I could update mine. motor is in progress of a second rebuild since I last updated, now it's a stroked 400 to 434 cubes, 13.5:1 cr, 680 lift cam 1050 dominator carb and all the parts to make it hold together. Tranny is a top loader 4sp with 1 3/8" input and 31 spline output to a nv 273 tease out of a super duty, haven't decided if it will be married or divorced, depends on how much room there is in the framerails of the new race rig. Motor will be flirting with 700+ ponies if it all works how we hope, and if not it will be made ;) but I ain't telling how.

Carbed and cammed LS3 with a TH350, custom billet transfer case thats married and has Pro Fab gears. Axles are a D60 Rock Jock front with a ARB, and the rear is a 9.5" 14 bolt (yes I said 9.5"):flipoff2: thats been welded. Trucks got 54" cut Boggers. Used to break the t-case before I put in the billet one.

I'll chime in as well.

Started. full size chevy minus glass and interior

Well worked over 454. HD th400 with bolt on yoke (thick case) well worked over as well and reverse manual valve body and trans brake, pro ratchet shifter, Divorce dodge 205 with 32 spine input and outputs, 1410 except for front output which is 1350 cv, 14 rear dodge 60 front. 5.38's yukons with detroits in both and 1410's. 35's and 38's boggers of course. Stock steering.

Changes all from 35's
Detroits removed now spools as both lockers broke.

Front shafts broke 4 stubs and two long inners on 35's. Went to 70 outers and non neck down inners. Had to go to 35 spline drive flanges got from east coast gear.

Stock steering went away to crossover and hydraulic assist.

suspension change in the works. 8" springs are good for hitting the jumps, sucks for dragging even with traction bars. In need of some fancy shocks as well.

Also having a fuel supply issue at the moment that I have yet to figure out.

Orielly replacement aluminum radiator blew the plastic tanks off the side. Went to a howe racing radiator all aluminum. Was the closest to the stock size that I could find and picked it up for 180 bucks.

Sir yes Sir! 4Low & 2nd gear @7000 rpm's for approx. 1 minute:eek: To conquer a LONG STEEP climb. I recall thinking: "If I don't make it I'm gonna roll back down the hill!" I made it.:shaking: So I kept on wheelin' that day thinkin' I had a "carb" issue.
What's really crazy is we found the lifter guts in the intake valley. The spring or other lifter guts could have very easily made it to cylinders.
I believe I was EXTREMELY lucky:D.

79 F250, 460, NP435, 205, LP44 front welded (thanks PO), D60 rear welded.

Breaks a lot of front shafts as would be expected, and the front yoke on the driveline once.

Future plans are a mild 512, 500 horse as a conservative goal. Cant decide on axles, I could build a D70 front with outers I have or run rocks, both are cheaper than a D60 front in these parts and would hold up better with the ags I want to run.

If I were doing mine again today, I'd sink my money into the rockwells. We didn't have any of the upgrades for them ten plus years ago, but these days they are a sure bet.

I'd definitely go that route. The beauty is once you start breaking stuff the aftermarket support is there to beef up the rocks as much as you'll need.

This winter I am upgrading my drivetrain as part of my build. I was going to swap in a built 440 but decided to go a different direction. I am stroking the 5.9 360 to a 408 which will be supercharger with a Procharger. Looking around 460lbs of torque and 600-650hp. The 46RE is being built with 48 internals and a forged main shaft full manual valve body. I run an Atlas II 3.8:1. The axles are Rockwells running an Overson spool in the rear and ARB up front. Putting in for the TTC Champions cup.
