14 Bolts and Big Blocks don't mix

Now you know why GM never put BBC in front of the 14SF.

Incorrect. 454SS pickups used the 14b s/f rear axle

This looks like a problem with the aftermarket locker, not the axle. Maybe a manufacturing defect? Unless a chunk broke off something else and got lodged in there.
 
Re: 14 Bolts and Big Blocks don\'t mix

Woohhhh Really???

Interesting... I wonder what the 454SS weighs...

I also wonder what locker (if any) the 454SS has...

I know mine weighs 5600 lbs. /forums/images/graemlins/whistling.gif

and I am afraid of Detroit rear in the snow...

Whats up with that? I dont get what the issue is with a Detroit and snow? I ran for 5 years with a TruTrac in the rear (limited slip) and never had a problem. Those axles were locked 90% of the time. Now I have a welded 14FF and ran in the snow most of last winter without any adverse effects. So why is the Detroit scary to you?
Dont get it.

That SUCKS /forums/images/graemlins/ignore.gif /forums/images/graemlins/ignore.gif

Pretty impressive though....
 
Re: 14 Bolts and Big Blocks don\'t mix

I understand running on an Ice covered road with a locker can be interesting at least.

Basically, I hear how some guys actually spin out with a Detroit in the rear when taking a turn on the ice because the rear-end comes out with the loss of traction because one tire doesn't spin faster than the other....

Actually that is not correct. The 454 SS trucks came this way from the factory.

In the '70s they made 1/2 tons with 454s and 12 bolts out back. /forums/images/graemlins/thumb.gif

The part that failed in your truck was not a GM part.
 
Re: 14 Bolts and Big Blocks don\'t mix

So does everyone think I could simply stuff a Detroit in there?

I won't have a problem with the Detroit right???

Or will I need an open carrier?
 
Re: 14 Bolts and Big Blocks don\'t mix

The Detroit should be the carrier in a SF. As for the Detroit on ice. It is not so much that the axles are locked together it is the locker engaging and causeing the jerk in the drivetrain.

That jerk is enough to break all traction and spin the rear end around.

I ran my welded 14bff on ice 2 winters ago. It was just fine for traction on ice. Just as good as or better then my limited slip I had before. The problem came when my transmission would upshift on turns (usually 1-2 shift on left turns).

The shift would cause enough jerk in the driveline to break all the traction and kick the ass end out. If I would shift the trans into 1st and not let it upshift to 2nd until I completed the turn it was fine.

One reason why I like a manual shift automatic....

The detroit for a 14 bolt SF is a whole carrier.

I personally wouldn't spend one dime on that axle. I'd get me a 14 bolt full floater right now.

Re: 14 Bolts and Big Blocks don\'t mix

I have one word for you, SPOOL, cheaper and stronger! /forums/images/graemlins/waytogo.gif /forums/images/graemlins/hack.gif /forums/images/graemlins/weld.gif /forums/images/graemlins/grind.gif

That is also a semi floating 14bolt not a full floating 14. The FF are stronger. ARB's are not available for them though. If you destroy a 14bff carrier with the detroit you have really done some awesome damage. That carrier is beef.

Yeah I seen it was a semifloater... My silver blazer (the DD) is staying 6 lug /forums/images/graemlins/waytogo.gif

Damn. /forums/images/graemlins/yikes.gif That is come carnage. ARB's are supposed to be one of the toughest lockers too. I think ARB's are warrantied but don't know for sure.

Sounds like I would be going to find a 14bff and a detroit or welded spiders.

Only locker I have seen eat it more that ARB with my club is the EZ locker. All the ARB's I Saw fail were all the same problem. The case bolts came loose and boom!
Now I will say that mess is the worst I have seen. Most of the time once bolts started hitting housing they know something was wrong and stoppped.
ARB is the V-Tech of the wheeling world.
 
Re: 14 Bolts and Big Blocks don\'t mix

The ARB in my rear Dana 60FF: I found 2 of the bolts (that hold the ARB carrier together) with the heads popped off. A third one was finger tight. Found this when I changed diff oil. This ARB was 12 yrs old with about 200 000 mi on it when I discoverd it. It was working OK. No noises or anything. Replaced bolts.
 
Re: 14 Bolts and Big Blocks don\'t mix

I swapped in my TBI 454 (stock) with my 14SF. I had no problems, I've gone to 14FF for detroit and because of doubler. It's also in a Sub. /forums/images/graemlins/1zhelp.gif
 
Re: 14 Bolts and Big Blocks don\'t mix

Welp...

Taking a closer look at the mess of parts, I see the big hardened rod bent!

So I am not sure if it came out and shattered the whole thing, or if the ARB brake and the rod bent.

Oh well..

14FF w detroit, here I come!
