Will a chromo shaft dana 60 front with a detroit and 14 bolt rear with a spool, both with 5.38 gears, handle 54" boggers for mudding? They'll be on a 78 f-150 with a mildly built 400, just cam, intake, headers, 4 barrel, maybe some TMI zero deck pistons, and a c6/205 combo. The truck wont see hard core rocks, just mud and trail riding. Thanks guys.

It might last for a while. But you will not be a happy with 5.38's, a 2:1 low range and a lopo 400 with 54's - that just isn't enough gear for half-decent performance. But that is exactly what might give 1 tons some hope for longevity with 54's. That said, my experience is that the biggest variable by far when it comes to driveline survival is the driver. If you are easy on it, it will last for awhile....if you the abusive lead foot type, it will not last. Regardless, that combo of parts is not desirable for either performance or reliability.

That 400 may be a mild build, but still probably 350 to 400 ft. lbs with a good cam, intake, headers,re worked heads, and all that smog shit gone seems to be possible. How low of gears does the bastard need with 54" tires? Like I said not rockcrawling, and possibly steping it up to a 620 hp 521ci cj motor if funds allow. Then again I may just go 44" tires. Its probably all I need, I'm just a kid with big eyes......lol Its a Marine thing, we always want the biggest damn toys. There is that burnt 7 ton in the motor pool.........................:evil:

What gear would work? I say about 6.72 to 1. with chromo everything.....

In other words just start looking into the rockwells? God d**m it, I knew you guys were gonna say that but I had to ask. fu*k. Welp how much diffrence is it mounting in a set of narrowed rockwells compared to a set of one tons? And are rocks street legal?

don't narrow them either. You'll probably be so high you'll need the stability.

Fuck that. High my ass. Im not building a show truck, and I was raised in Tenn. I know exactly what a sawzall is for......... I have no prob. cutting fenders to make the bastards fit. Im keeping as small a lift as possible. Probably a 9 inch still, but a 6 if I can manage it.

What exactly are you going for though?? Look or performance?? IMO, you probably have plenty of drivetrain and gear to make them work and survive....but you don't have anywhere near enough motor to make even 44s work well in the mud. People drastically under-estimate the HP needed to make boggers work well in the mud.

Performance............I couldnt give fuck all about looks. Long as it goes like hell, and is still semi street legal. Tenn doesnt do inspections so you can get away with a hella lot of shit before you get pulled over, especially in the boondocks where I live.

You think I'm stupid enough to post on the infamous pirate asking about a rig that I want to look good..............Yeah right, I'm gonna get flamed enough as is and I'll I want is a bad ass mudder, that can drive to and from the bog with out to many funny looks from cops.

Your gonna get alot of funny looks with rockwells and 54s stickin out

I can't believe nobody has flamed you for posting that shit on here already.:laughing:

scrap the 14 bolt, get a D70, run 6.17 gears, or 7.17s.

I wouldnt waste the money on 1-tons, Rocks are cheap and give you more options as far as set-up. Just my 2 cents. But then someone on here will tell you they have D-30's in a daily driver spinning 54"s in the rocks on Saterdays and running 10' of mud on Sundays.

I personally know a guy who was running 54s on an old chevy with 1 tons that he'd dropped some major coin in.

Running just mud with stock 85 350 he destroyed the ring gear in the front.

54s are for rockwells.

You're gonna need more than 9" of lift to be able to turn with those tires.

Rocks are much cheaper in the long run and the gear ratios perfect.

With my rocks and a 205 my gear ratio was pretty good with my mild 350, but I'm about to drop in a 468 on nitrous so the boggers work the way they were intended.

Xeleventy billion. You don't need to be an ass to get your questions answered.
I'm sure you have discovered that this place is a hardcore rock crawling site, not a mud site because sucks ass.
If you have to ask if tons are enough then you already know.

I'm not trying to be an ass. I was simply saying that asking questions about mud rigs on pirate may not be the best idea to avoid getting flamed. A change in tire choice may be in order here. Just cause the budget allows 54"s doesnt mean it allows the componets to run them . And you gotta build a complete truck not a set of tires. So would 44s be asking to much still? I remeber when 44s where(are) massive and every hard core rig at TTC had dana 60s and 70s, with maybe one rockwelled rig out every 50. Times have changed I guess.

I would not buy 54" boggers unless you already have them. Go with rockwells and an implement tire. When it comes to mud nothing beats a tractor tire. Your going to spend thousands of dollars on a 60 just to bring it up to strength of a rockwell. Rockwells with 2" shafts will cost you the same as a modifed 60 and there damn near unbreakable.

for what it takes to fit the 54" boggers you wil be able the fit the rocks with out issues

only chance you have is to run longs, and even those aren't recommended for tires over 47's. You can't be cheap with 54's, buy the rocks, you can easily build up a set of Rocks with discs brakes for the same price as a built 60 with longs.

Do yourself a favor and go with V-treads. Im not saying they're better, but they will save you some serious dough. I traded my stock CUCV 1-tons for a set of take-out rocks, and it was well worth it.

the axles will survive from a lack of power to be able to make them tires work properly, point in case:

that bronco has just the right amount of power to make 44's work (with 4.56 gears) (granted those are 42" tsl's, but thats so he can have some type of control), and he's pushing 650-700ish hp, i'd step down to a 39.5 bogger or 42" tsl, then tire and motor and drivetrain are closer matched, and i'd then run 5.13 gears, remember rule of thumb in the mud is wheel speed, the more you have the better your chances.

If in doubt, check out the Chevy truck in the 2008 TTC.

Running 49 inch Iroks on a Dana 60. And halfway through, he busted his ring and pinion.

No big surprise really.
