ok well after tons of research and more reading than i ever thought id ever do about a lot of things im curious to know:

1: has anyone broken any PROFIELDS?

2: has anyone broken any 4140 cromo inners?

3: has anyone broken any 4340 cromo inners?

4: has anyone broken any of PIG's inners with the new design?

5: in your opinion are 4340 inners worth the extra money over 4140 when just buying inners?

6: those who have experimented with profields, old longs (with the ring), and new longs (without the ring) which seems to hold up better?

7: if you broke any of these products how is your rig setup (engine, trans, gears, lockers.....)

Heywood on this board broke one of AP's 4130 inners with 37's, 3.0 V6 and 223:1. Wasn't really abusing them and it was there first trip out, 1st trail, about 1/4 through Outer Limits.

He also had a older ringed Longfield on there that started clicking a lot after the inner gave out, but no visual damage.

I believe camo broke 1 or 2 of the 4130's, and a pair of older 4340's he had custom made???

I believe Zags broke a Profield during his testing stages. That's the only one I've heard of. I'm gonna go punish my new style Longs and new 4340's from PIG at the Hammers soon. Hope they hold up and no more R&P failures, but now I have spares

i'd have to look back at the thread, but did zags break the profield after it was redesigned. i know he busted the first design fairly easily, but then they went and redesigned it (before we even heard they were going to be making a birf) to be more like bobby's new longfields - did he break that one as well? :digging up old thread:

edit: heres zags post about the testing (snipped a little blah blah off the top )

[snip]
I was contacted some time ago by All-Pro about testing some new birfields they were develping. I thought it would be fun so I readily agreed. To be honest, the first prototype was disapointing. They were about on par with Newfields. I have run Longs for a long time and used the durability of the Longs as a benchmark. I called them with the results and they were disapointed to say the least. [snip] The set I am testing now has survived a few dozon runs up some of the best Arizona has got to offer. I was running them in my new buggy in its first comp and they held up to full awn tire smoking, pedal to the floor abuse with no problems. I was concerned that my buggy was too light to really produce an objective test, so I put them in the old red truck, setting the stops to aproximately 35 degrees from straight ahead. After being satisfied with them running trails, I spent an entire day just jamming the front wheels under every nasty ledge I could find. I finally got a bang out of the front axle, took it apart to find an exploded front hub. No spare. Bummer. On my last trip out with them I was on mission to come back with something busted. We found some big brutal rocks to play on near to the tow rig and went to town. I spotted my friend Matt (the current owner of my old rig) over every nasty spot we could find. After a few hours of this, a miscue on my part landed him on his side with the RF in a big nasty hole with the wheel bound tight. He was in double low, so I told him to try to back out of it. Since the wheel was bound tight I knew something was going to blow. I didn't get the usual birfield bang. The wheel just quit turning then started to jump.
We finally Hi-Lifted the rig out of the hole and surveyed the damage. What I found was that the splines on the inner axle had sheared. It was one of the first Chromo axles All-Pro sold that had survived some birf failures, the hub failure I mentioned, and one very nasty ring and pinion failure. It did damage the birf, cracking the inner star.

[snip]

I have tested them so far with chromo axles only, on 37x13.50" Mickey Thompson Comp Claws (bias ply), 223:1 crawl ratio and an ARB locker.

edit2: okay, im4yotas was right. he did break one of the new ones. dammned if i didnt miss that.

well shit, am i retarded or what :rasta: i thought i had read that one broke at some point, but couldnt find it and thought it was in another thread. turns out it was right there :emb3: oooooooops

ok well after tons of research and more reading than i ever thought id ever do about a lot of things im curious to know:

1: has anyone broken any PROFIELDS?

yes

2: has anyone broken any 4140 cromo inners?

Not sure what AP's original cromolly's are made of but I broke both a long and short side in one day after a year of hard wheeling

4: has anyone broken any of PIG's inners with the new design?

I don't think so but this is way I'm going after i scrounge up some cash or burn threw the pile of stock axles I have laying around

5: in your opinion are 4340 inners worth the extra money over 4140 when just buying inners?

Even if you don't brake an axle, you always risk boogering the splines. It's a risk you have to take. I think PIG's got the best product for the best price on his cromolly's right now at $219 shipped

6: those who have experimented with profields, old longs (with the ring), and new longs (without the ring) which seems to hold up better?

I broke the stub off an original long after a lot of trails and twisted the splines on a new one on it's first run. For me the weak link in these has become the stub. Now i'm running an original long with tons of trails on it on one side and brand new one in the other. we'll see which goes first. If you've been following the threads, some people are having good luck with Pro's and long's, some are not.

7: if you broke any of these products how is your rig setup (engine, trans, gears, lockers.....)

standard truggy, welded f/r with 4.10's, dual cases with 4.7's, 22re and 5spd on 38.5's

 

[OOP'S]

Nothing is "Bullet Proof" If you can't break it, Camo can!!!!!

 

[zags]

I was going out of my way to try to break the second one. I really couldn't be sure, but it appeared to me that the 4130 used and abused axle failed first, resulting in the cracked center star. That axle had seen recent hub, ring and pinion, and several birf failures prior.

went over to jigga's house yesterday, he had the new style birfs that got waisted(one at hollister, one in the driveway) and both had the stub shaft 'torn' off the bell. the ring design may not be the isssue, maybe the supplier of the core birf assembly?? (as he stated before his post was deleted?...)

who knows, youve got people wheelin just as hard in heavier rigs having success with the new birfs, only time and others wheelin on them will tell...

interesting thoughts and experiences... the main reason i ask these questions is that i havent really heard much good OR bad about profields as it seems everyone is whining about their longs... seems like too many people want the impossible out of these "super birfs"... and then theres people who want the ring welded on and some who dont blah blah blah.... looks like it only costs about $12 more to get the 4340 inners if you buy the profields/4340 "package" as opposed to buying the 4140's and profields separate ($399 for the "package" or 129 each for profields and 129 for the set of 4140's-totalling $387) unless im sorely mistaken... still some thinking to do before i order anything but after everything ive read, the 4140's do well but the 4340's do better, pick a "super birf" and be done with it
