10 bolts and 39.5" tires???

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

what's going to really hinder you is that front locker. I've got a D44HD under mine and when she finally gets on the road again, I'm crossing my fingers not to break with 36's. I left the front end unlocked though and that was half the reason...

Driving style will dictate if you break or not past that...

10 bolt rear axles regularly grenade in on-road only use with stock size tires. Check some of the boards that newer truck owners frequent.

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

Seriously guys, I don't know if you read too many magazines or what, but 10 bolt fronts are just fine.

If I had my choice of 1. keep my current axles and get 4.88 gears or keep the 4.10s and get 1 ton axles, I'd keep my current axles. I've tried over and over and over to break my frontend and I can't do it.

When I go off-road, I'm not easy at all on parts. I've destroyed both a 12 bolt and a 10 bolt rear, but never broken a front.

You guys with the 1 ton gear talk about it as if it is even required in the mud on a lightweight vehicle like a Blazer. That's just absurd. You either rock crawl or you read too many magazines and think that your front axle isn't any good.

I started a thread a few weeks ago about who'd actually broken their axles. Only two or three people that didn't rock crawl had broken a front axle.

1 ton gear is nice, me and especially my friends would love to have it, but it's just not necessary in mud. Mud doesn't offer enough traction to break axles usually, and if you do break it, you have a very heavy foot and probably a big block.

"I've tried over and over and over to break my frontend and I can't do it."

Try locking the hubs first. Maybe even put the t-case in low.

"You guys with the 1 ton gear talk about it as if it is even required in the mud on a lightweight vehicle like a Blazer."

Last time I weighed my Blazer it was 5700 lbs empty, no people, &lt;1/4 tank of gas. Not what I'd call lightweight. Especially when you figure that &gt;50% of the weight is on the front axle.

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

I broke a 10 bolt front. Actually, I broke a joint on one side and toasted a shaft on the other. That as 10 minutes out of the driveway w/ 36" tires. What was I doing you ask? I drove my truck up a mound of dirt to meaasure for shocks. I was in 4wd and I have a front locker, I also run slugs, not hubs. Now, you tell me. WAS THAT HARDCORE? I don't think so. I doubt seriously that 39.5's or 44's are gonna be any easier. Read to many mags? Doubt it. Cole Quinel ran his mid 70's pickup for a LOOONG time with a 44 front. He also maid the statement that it scared him and he was just waiting for the break (IT DID HAPPEN TOO). I wasted a 10 bolt rear pulling away from a stoplight. I trashed my first front going down the highway.

Look at the guys website and see what kind of wheeling he does. Doesn't look to me like its mud runs. Before you become critical of someones advice, find out if yours is any good either.

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

How old are you?

For 39's it IS required to run one ton running gear when you go offroad. And a blazer is not exactly light.
10 bolts and 39's might be okay for mall running and occasional curb hopping.

If you've ever been mudding, you would know that a lot of times you have to get heavy on the gas or yer gonna sink...of course, that's with REAL offroading, not pansy stuff.



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

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

I figured i would get most of the replies i got
smile.gif
I was just curious, that's all. But one thing does have me wondering, alot of you are saying the front 10 bolt is stronger than the rear. I really dont see how that is possible? The way i see it the front U-joints on the shafts have to be weaker than the whole rear axle? I may be wrong though.

Thanks everyone. I am in the process of saving for 1 tons and the new tires &amp; rims. I would rather have the 1 tons and not need them, than not have them and need them

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

I sure its possible. 10 bolts are strong if you build them correctly and maintain them. For instance I have a 10 in my 69 firebird. I put new gears and bearings in it with an aburn pro. The axles are original. I run them with 28x10.5 MT slicks. Its been that way for three years now, and no problems. My car is pushing over 500 hp and 700 ft/lb of torque. I abuse it every Friday night.

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

I'd bet a front locker would destroy one every time. Any time that a good amount of power only goes to one shaft it'd be real easy to destroy one.

Mine is open right now, so are all my friends. I considered locking it but I'm pretty sure I'd break it then.

Try locking my hubs and using low? How about locking the tranny in 1, the transfer in low, removing the rear driveshaft, and screaming through any mud pit around here? I bet it still wouldn't break. My friend's Suburban would probably have to pull me out (oops, it's got a 10 bolt front too, I guess it wouldn't make it out there to get me even though I'd only have 1 wheel drive).

1 ton gear would be nice, like I said. But my friend runs 39.5" Boggers and a built oval port 454 big block on a D44 front and only broke it once in the last three years.

Believe me, every one here would call what he does hardcore, and the driver is absolutely insane. We'll see if it breaks with this new 4 speed. It could only break once with an automatic.

The other two guys have destroyed driveshafts but never an axle (especially the K10).

If your Blazer weighs 5700 lbs. my K10 has to weigh close to 6,000 then. My friend's K10 has to weigh even more since it's a longbox, has a full floater, and has 44" tires. The K20 with the big block has to be close to 7,000 lbs. The Suburban has to be so big I'm surprised that it even moves with a 350.

Either that or you've got a whole bunch of crap stuffed in that Blazer or it doesn't weigh anywhere near 5,700 lbs. My truck weighs an estimated 5,000.

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

Back to the orginal question. It seems that some people can get away with running 40'' tires or bigger on the half ton stuff and never have a problem for some reason. Kind of weird how some people encounter breakage all the time and others don't. Of course, driving habits do have something to do with it as well.

Never put a stupid move passed a stupid person.

I'll call bullchit on this one too. I don't buy it.

While we're at it, quit talking about my friends this and my friends that. You tell us we read too many mags then all you can do is spout off stuff that "your friends" are doing or saying.

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

I wouldn't say that Blazer is lightweight,especially w/diesel,dual batterys and winch up front.That's lot of weight for front axle

I'm too lazy to stick shift,that's why I prefer autotranny.
 
Re: 10 bolts and 39.5\" tires???

Lets think about the logic. A blazer is pretty much a pickup, with a heavy camper and interior in the back, with a seat and back glass, yadda yadda. A pickup is the cab and bed. Have you ever seen how easy it is to bust the tires loose on a truck and then try it with a blazer?
I've owned pickups and they are not as heavy as a blazer.

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

I have weighed my truck in trail trim, on 36's D44 front and a soft top and it wieghed 5300 lbs. Add an interior, a hardtop, fill the tailgate with the motor, regulator, glass etc. and 5700 is sounding light for a Blazer. Very few people here would post the weight of their K5's without having checked it first. Every wieght i've seen posted has been in excess of 5300 lbs. A few have topped 6000 lbs. Do us all a favor please. If you are going to make claims about 10 bolts, or wieghts have the info to back it up. Have you weighed your truck? Have you ever weighed a K5? Have you ever run through a mud pit in "one wheel drive"? Until you have first hand experience to back it up please just sit and read unless dining on yer own feet is something you find entertaining.

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

I had a dually(reg. cab)....I mean a dually! If you were to get a heavier duty dually, you'd be going to a bigger class truck. The dually was at 4700. That was when it had the diesel in it! I had a half ton pickup. 4000lbs. A 305 made that thing fly. A plain jain 350 don't make any of these blazers fly.
So there's some acurate numbers.

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

"Either that or you've got a whole bunch of crap stuffed in that Blazer or it doesn't weigh anywhere near 5,700 lbs. My truck weighs an estimated 5,000."

My truck was weighed on a scale. How was your "estimated" 5000 lbs determined, Cheif?

"How about locking the tranny in 1, the transfer in low, removing the rear driveshaft, and screaming through any mud pit around here? I bet it still wouldn't break."

Again, Gimma da keys, I'll drive!
