Dang noone recognizes the first huge leap of toyota axle tech when they see it?

lowgeared · « **Reply #2 on:** Jul 19, 2004, 05:18:07 PM »

Who's making these? I am still the only one of the group that still runs stock birfs in both the pickup and 4runner and the pickup is welded! I am sure my time will come, but I really enjoy going against the odds. A bullet proof cromo setup like that would be cool.

WHITE_TRASH · « **Reply #3 on:** Jul 19, 2004, 05:31:19 PM »

There are really only two people that would have the ability to get these to market, Pig from www.polyperformance.com and Bobby Long. These are Bobbys axles. Pig has some 300M :frickenwow: birfs and inners coming out later this year. Those should be killer but at nearly (estimated) triple the cost of these, guess where my money will go. These should be about $600 to your door.

I remember seeing some aftermarks birfs (Newfields, Smurfields??) don't remember which-they were actually built oversized. You had to grind on your housing to get them to fit. They also looked pretty impressive but haven't really heard much about them or seen any writeups. I don't know what material they were made from either?? Bobby Long is at the top of my list, I try to support people in the same state as me. Met him at NWRCA in Vantage in that cool red buggy thing of his. Hey Marlin...why don't you guys move to Washington and WT and I will both come work for you!!

WHITE_TRASH · « **Reply #5 on:** Jul 19, 2004, 05:44:12 PM »

I met Bobby at Goldendale this last year pretty cool guy. You know, as much as I absolutely despise california Id move there if I could work at Marlins shop. But having one in WA would be killer!

Hyena · « **Reply #6 on:** Jul 19, 2004, 06:34:25 PM »

I havent met anyone

If you had 300m birfs and inners, then wouldn't your R&P be the next week link? People with 4.88's or higher should watch out.

Gtown · « **Reply #7 on:** Jul 19, 2004, 08:00:48 PM »

If I were to buy these, in my opintion a waste of money, I would have my gear sets treated by bobby. But then your hubs go, so all part of the process.

lowgeared · « **Reply #8 on:** Jul 19, 2004, 08:04:53 PM »

You know what would really kick some ass...hub fuses. Have them fail before the axle or r&p. Warn makes them, but not for Toyotas. Easy 10 minute trail fix and your back up and running.

donkeykong · « **Reply #9 on:** Jul 19, 2004, 09:37:46 PM »

There will always be a weak link. Even if you have chromoly everything something is still weaker than everything else.

84runner · « **Reply #10 on:** Jul 20, 2004, 12:19:35 AM »

Hub fuses

never heard of those will have to look into that. And Just for the record I am still running my stock birfields and have broken a rear axle and yet to break a birfield

derek · « **Reply #11 on:** Jul 20, 2004, 06:23:09 AM »

i have popped 4 birfs, 3 inner axles and 1 longfield.
i am really looking forward to the testing on these.
i hope they turn out to be a good product.
it may be a future purchase for me unless i just go 60 up front.

YotaYota · « **Reply #12 on:** Jul 20, 2004, 07:29:35 AM »

WOW

, I wonder how these compare to the birf eliminator, yeaa the next weaakest link for me would be my r&p(not w/ a hub fuse), but youd be able to turn your steering stops all the way in, my truck will be trailerd next year so i may step down to 4.88 or 5.29's. This quote comes from SKY's website :

Need a little extra axle beef? This is the kit. Running 37" + tires on a Toyota axle is pushing the limits of the stock parts. The Birfield eliminator gives you some room to work with. Tested on various competition buggies, run in the real world, used by us.

The axles are constructed of 4340 high nickel alloy, with a 760x u joint. You may upgrade to CTM's or Aussie Joints. Kit includes all new axles, spindles, seals, u-joints, and instructions.

Currently I run either 37 inch MTR's or 39.5 TSL's. Recently while on a snow run I backed up a dirt bank with my 5000 pound 4 Runner, running my 37's. This wall was about vertical. I turned my wheels to the right full lock, my stops are actually turned in as you can turn tighter with a u-joint, and tried to move forward. Apparently the ditch was deeper than it looked, and covered in 2 ft of snow. I was digging down, not moving foward. So like most people, I took the motor up to 4500rpm's and dropped the clutch in reverse, full steering lock. Last time I did this with a set of HD Birfields and Chromo inner shafts, I spit the inner cage out of the Birfield. This time I still had no movement, but nothing broke. 3 more tries and I was moving again, much too the amazement of the other Toyota owners in the club, with no broken parts.

And jus look at them:

The smurfields are stock birfs treated by a guy in canada..Cheap and he has a trade deal going for guys to get free smurfields...I have herd nothing but good things about his stuff..Comparable to bobby's stock treated and ringed birf...seems like a hasstle to get though because of customs..I am going to try a place here in oregon in newberg called nw cryo..They said 20-25 bucks to cryo treat a birf and axle..

I'd like to have a set of bobby's 30 spline axle and birfs,,and a set of pigs to try out..Will be interesting to see some test results..

Yeaa, I cant get it to work. Theres a pic on marlins main site, under axles. Theres only two people that I know of running the birf eliminator, sounds like w/ good result, Im really considering this as an option, so if you guys or anybody you know is running these let me know. Maybe Marlin or BigMike has some info for me (will buy from you if you have positive feedback)

Prism is runnning a old redline birf elim. kit in his runner.

81Toy4x · « **Reply #18 on:** Jul 21, 2004, 08:08:55 PM »

So if you run a birf eliminator kit pretty much all you can break is u-joints? Or is it common to break those axle shafts too? The ony thing I'm worried about with birf eliminator kits is someone making them then coming up with something new or go out of business or something, then I am kinda sol if something goes wrong. I'll probably never upgrade my stock birfs. I don't wheel very hard so I probly won't break em, and if I do another stock birfield will go in.

mr4x42u · « **Reply #19 on:** Jul 22, 2004, 12:03:47 AM »

no,those kits break stubs and axles as well as the joint.

81Toy4x · « **Reply #20 on:** Jul 22, 2004, 10:29:59 AM »

Oh okay. So I would rather just keep something stock in it that I can readily find at junk yards and fix.

But the main question here is - Are these kits stronger, weaker or pretty comparable to the longs that WT's first post shows

Thats what I wanna know.

Prism, Chime in, how are they

Any complaints ?? Are the worth the 7 Bills that they sell for??

HyDesertMutant · « **Reply #22 on:** Aug 05, 2004, 12:37:50 AM »

I guess I'll start thinking about these things when I break a birf. Hasnt happened yet, but then I run a TruTrac in the front and try not to throttle up a full steering lock....Yeah I guess Im a wuss, but I'm poor and I gotta watch my repair bills.

CTENG in KS · « **Reply #23 on:** Aug 05, 2004, 12:31:00 PM »

Its ok bro, I am running the tru trac in front too, no birf problems and I just hit a little brake pedal to get the front to lock up. I get up the trails so it all good in da hood.

88runner · « **Reply #24 on:** Aug 05, 2004, 01:42:48 PM »

I don't see the 30 spline as a huge leap, what is one is the fact that the axle shaft don't neck down, have no groove for the external c-clip and the fact that it is in 4340. The 300m ones should be awsome, but then r&p and lockers are more expensive then birf, so I wonder if it's really good to make a birf bomb proof. I don't know for you but I have no experience in installing gears so heach time I would change I would have to paid to have them in, maybe I would learn with some practice.

Maybe I'll do my own, I can have axle shaft made out of anything I want

for the cost of the material

Thats hard to say..I would bet there stronger..But it also depends how there abused as well..Only real world testing will figure it out..

A good quality ring and pinion are pretty strong (almost indestructable)when you get to sizes of 4.56 and up..I would still worry about busting an axle or birf before the ring and pinion..Again its a mattter of how you beat your junk..some wheel there rigs,,,some beat the shiat out of them..

Island4Runner · « **Reply #27 on:** Aug 06, 2004, 04:39:12 AM »

The reason for the 30 spline design is to elimanate the neck down in on the birf end of the inner shaft, wich is the week point... What makes the birf itself stronger is the design of the birf itself..The bell is longer, the inner race and cage is a completely different and stronger design, the balls are smaller to give the bell and inner race added thickness, all are made of 4340.....

Now everybody is thinking ok cool but now wheres the week link gonna be, the hubs, the r/p,?

? There are tricks out there to improve the hubs, bigger studs, hendrix motorsprots 4 pin hub mods...Bobby offers his heat/cyro treatment for the r/p....

For those that feel that they dont need the 30spline, dont want to risk breaking there r/p or hub's bobby has said that he will be offering the new design birf's in stock 27 spline to, for $225each.....Eather way id say great days for toy axle owners are comeing $Beer Chug\'n$ $Beer Chug\'n$

this is quote from the man himself in a reply over on the Pirate board

Quote

O.k. the cats out of the bag! The prototype inner race is 4340 but the final product inner race is made of 300M and will be longer. Yes, the inner cage and race is a patented design. The price will not change it is still at $635.00 a set, all 4 pieces. We feel this will be the strongest birfield on the PLANET! I want to design something for you guys that we can beat on with our eyes closed.
