10 bolts and 39.5\" tires???

How many people are running these size tires or similar with 10 bolts. I am considering running these tires with my 30 spline 10 bolts. Was wondering how long they might last wheeling about once or twice a month and driven everyday? I do have a detroit locker in the rear and Aurburn in the front if that matters.

I am pretty sure the concensus will be wait to get 3/4 ton or 1 ton axles before i go this big, but i am wondering if there is anyone out there running this combo or similar and making it work?

Thanks in advance,
Joe

Believe it or not, I know a local kid that is running that combonation, but on the street only. This week I have also seen a brand new Dodge P/U running 44" Boggers, it has a huge lift and stock axles. Both are accidents waiting to happen.

Sorry Joe, but this combo is not gonna work. Believe me I ran that same setup for quite some time and almost every trip I had to replace an axle or an axle U-joint. Then there was a time when I couldn't just replace what I broke. So if you carry enough spare parts with you and you want alot of practice on trail repairs then go for it, but I wouldn't do it.

Re: 10 bolts and 39.5\" tires???

My friend ran 44x18x15 tires on his stock 28 spline 10 bolt front/12 bolt rear, 6 lug. Now he has a 10 bolt/14 FF and the same tires. He ran it through the mud bog competition and was one of the only few to make it through. He has a 350, SM 465, and NP 205.

Another friend of mine has a '76 K20 with 39.5" Boggers. He has his stock D44/14 bolt full floater combo with a built 454, SM 465, and NP 205. He was the first person to make it through the mud (and the first to try) in the competition. He broke his front axle once last winter, but other than that, he has never broken a front axle.

My other friend has an '81 K20 Suburban with 44x18x15 Gumbo monster mudders. His driveline is bone stock as well, 350, SM 465, NP 205, 10 bolt, 14 FF, no problems, never a broken anything.

Try telling me now that 10 bolt or D44 fronts are weak. Maybe a 10 bolt rear's axle bearings couldn't take it, but I promise you that front axle will as long as you're not a rock crawler.

Re: 10 bolts and 39.5\" tires???

Why not try the Warn hub fuses?

If it's too much tire, you'll strip out a bunch of hub fuses, but they may keep the front alive.

You can also run cheap parts store joints on the front driveshaft so that they might break before the front axles, letting you know to back off.

Also, air down and just stay off that throttle as much as possible.

Lift It, Lock It, LIVE IT!!!
 
Re: 10 bolts and 39.5\" tires???

The fuses would of been a good idea, but on my last wheeling trip here in some local mud pits I busted an axle U-joint, fixed it, then got on it again and then broke my tru trac. After that I decided it was time for an upgrade, so after some searching I found a D60 and slapped that under my K5. Also got a 14ff for it, but it's not under there yet.

How could you tell he was jealous? Just because the only time I've been stuck is pulling out a Suzuki &amp; a Ford! Anyway I did explode the rear pumpkin but it was because of the ring gear spacer between the carrier and ring gear the previous owner had installed.

Re: 10 bolts and 39.5\" tires???

Dude don't be scared! I know just where you can get (4) 39.5 TSL's on 15x12's for a really good price! Then I can have boggers all the way around! WHEEL IT HARD!! JUST WAIT TILL THE NEW 10:1 CORVETTE 350 WITH NEW WORLD PRODUCTS S/R TORQUER HEADS MAKES IT'S WAY UNDER THE HOOD. Then we'll see what the 10 bolt and 12 bolt are made of!!!!!!!!!!!!!!

Re: 10 bolts and 39.5\" tires???

Small block and 39.5 boggers and you're exited? I guess so. My friend with the built 454 says he wants more. I think he's building a 496 or something. I can't see even wanting a small block with that much tire. I hope you've got a stick shift and an awful lot of gear.

Hey, just do it and let us know what breaks.

Never put a stupid move passed a stupid person.
 
Re: 10 bolts and 39.5\" tires???

like someone mentioned earlier just get a 14bolt in the rear and you will be fine as long as you arnt crawling crazy style.

Re: 10 bolts and 39.5\" tires???

I've seen lots of broken 10 bolts on the street w/35" + tires. Knew another guy that blew 2 or 3 9"s in a Bronco w/a 302 and 38s on the street. If you really want to run w/10 bolts, try getting some of the ones from a truck in Illinois, apparantly they are stronger than 1 ton stuff. :D

Re: 10 bolts and 39.5\" tires???

Sometime ago there was a SWB Chevy in Petersen's with 10 bolts and 44's and they were runnin it for a while. I think the key to his success was the 2.73 gears.

I think that is the key to any combo like that. High gear and big tires.

Re: 10 bolts and 39.5\" tires???

E101,

Boy I sure hope that guy with the 44"s and 2.73 gears has a whole garage-full of extra transmissions!!!! Can you imagine the HEAT that guy must be putting into that tranny? 65 MPH is only 1350RPM......and that's with a NON-overdrive transmission!!!

.....maybe he just drives it in 1st gear everywhere?

Re: 10 bolts and 39.5\" tires???

Can you do it, well of course you can slap some 39.5's on the 10-bolts........just drive real easy and keep your fingers crossed. I've broken several front 10-bolt parts with 35's and I don't hammer down on the throttle at all and there are not many rocks around here. Sure, if you just drive straight through a slippery mud pit then they might do okay but get out on a rutted trail and it might be another story.
There's a couple of other guys in my club with fullsize trucks, and they scattered front 10-bolts and Dana 44's left and right with 350's and 38" tires. They have also broken a couple of Dana 60 stub shafts with 42's and big blocks.
Again, if you watch what you are doing you can get by for awhile, but once you start doing any type of serious wheeling then you might get into trouble.
 
Re: 10 bolts and 39.5\" tires???

I'm gonna be running 35's with a 12 bolt and am a little worried about the 12 bolt. I think you would tear that up real quick. Keep it on the street until you can upgrade. You really need a 14 bolt for that size tire.

It's been lovely, but I have to scream now.
