sounds like we need to get a sample of how many people would be interested in 4340 rears for an fj40. :D i know this forum is just the tip of the iceberg for there client base, or i guess it is.

anyway, i guess in deciding one would need to ask themselves;
1.-if they wheel hard enough to break a stock 40 axle, which is pretty darn beefy as is., tire size would help with this part.

2.-if your gonna build the front to handle it like we do, would you like the piece of mind the cromos would offer.

3.-are you one step away from going d60s front and rear anyway so why bother.

4.-do you like keeping it cruiser so build the cruiser axle to take it.

i have no clue what it would entail to start a full prod. run on these, or how much interest would be required to make it profitable........maybe hit mud as well. :D

Would work in a full-float set up fine...

According to the folks at Dutchmans motorsports, they would not make a semi-float axle out of 4340....

Something about stresses in this application....

I would definitely buy 60 series 4340 rear axles. I suspect a lot of the guys running SOA wagons would too, as this is a weak link.

build a stronger pinion first !!!!!!!!!

Agreed.

So I guess that means I'd buy the Short Side FJ40 4340. :flipoff2:

Installed the chromoly inners and birfs in the front before Rubithon. But I still carried spares - for other people. :)

I'm in for 1 or 2 sets of stronger (whatever they are made of) FJ40 rears.

so that could be a deal killer,........ what do they make HD semi-floaters out of .......or is this even an option for us?

i have the warn ff kit id be interested in those if you made them in 4340

Id be down for those. Hurry, almost time to have my customs made..... :grinpimp:

Spend the same money (if not less) and get yourseld a OEM full-float... Still not bullet-proof, but it has solved many of my problems... I went through 3 SF shafts in ~6 months, havn't had a FF problem in 1.5 years, same trails, same thrashing, and now a heavy trailer out back :D

And when (not if) they break, I can swap it back at camp, etc... And aftermarket HD shafts are already available... :D

Sorry Hijack= Kurt HD Full Floater shafts available?? PM me a vendor. Thanks.
Hijack Over.

is there a quality aftermarket full float kit available? i know the warn kits are no more.........any others?

in theory black diamond bought writes to the ff kit from warn and will be making them

PIG can make them (and has), not sure on the quality/fit firsthand. I also had a local machine shop say they can do em too (they so stuff for Tera, Advance Adpaters, etc). The only thing holding me up is the fact I am yet to actually break a OEM FF. I picked up 9 axles in Cali two years ago... all of them are installed in trucks and too my knowledge no one has had a shaft failure. And in fact, I think I would rather have a shaft fail (in a FF of course) then a pinion...

Hijack over :D

Black Diamond was Warn's supension/axle line... it was sold to a company in the Midwest... too my knowledge they have no interest in making it again. Front Range Offroad has a FF kit for the mini-truck crowd, kits like it have been fitted to Cruiser axles using OEM stuff. If I were absolutely against sourcing an OEM FF, I would use drum brake spindles, etc and make my own, then get a inner made with splines at both ends...

I'd buy a set, but I am still concerned about their longevity in a Day to day driven truck.

Any clues on this one?

all this FF talk has got me thinking; fixing ANYTHING on a semi-float is a pain in the butt

FF would give piece of mind........or dana 60. :rolleyes:

Hey Kurt,
Whats the going rate these days for a FF rear?Also a source?

Hey Henry;)

There are plenty of guys running 60 series rears on 40 series rigs just to get width. We are breaking them. I think it's something aobut 38" tires, and 200-something to 1 low range. If you do these axles, please cover 40 and 60 series. Please. Thanks!




I would definitely buy 60 series 4340 rear axles. I suspect a lot of the guys running SOA wagons would too, as this is a weak link.

Also, along this line, please eread Woody's article in Toyota Trails this month. While not FF, it easily could be, and there are plenty of folks making upgraded axles for minis. With this solution, you keep the biiig beefy tlc center section, and get outers that can ff and be upgraded. Caveat: then you're centered, which requires more driveline mods. Which can also be good. Marlin has several answers to that question.

man a fee and sor have them. I have broke one long side rear and thank god I had a spare.4340 inners no thanks. The only thing keeping me from getting a FF is the cost for one and the abillity to find spares.SF axles are easy to find and are cheap.(I enjoy trail repares) If shafts for FF are made available(production) and easy to get I would go in that direction. As of now I am staying with my SF and waiting for that day.

Im in.. Just another reason to put off fullsize...and a bigger aftermarket.

Just in case anyone was intrested....Moser ind. will duplicate 60 series full floater axles for $ 315 a pair cromoly...

what about useing the crusier center section and ford 9" tubes and custom axles? would be semi-floater and 9" axles with 6-lug flanges couldnt be that bad. would there be a problem with this or am i missing something?


chris :cool2:

$400-500, SOR or the guys up in Canada

PIG makes HD ones, and you can still get a set of the OEM ones (used of course) for $150 (shafts only).... I easily spent that much on all the SF shafts I broke, and its hard to put a $$$ value on having a broken SF at teh begining of the Little Sluice ;) :)

Hmmmmm.... :D

With the correct taper for the cone washers at the hub? As I recall this was the only hang-up for most axle shops... but a local machine shop assured me they could do it...

I would be interested.

Heck Yeah I"d buy em! (need FJ60 length tho!) short is same, long is different!
At Cruise Moab.. I traded Kurt (2) FJ40 long rear inners for one spare fj60 rear inner.. Whelp, I ain't got no spare no more! I have never broken a rear inner before but in the last year have seen at least 4 or 5 of em break.
I've upgraded to Fine spline pinions, upgraded to pig inners and upgraded birfs, upgraded to aisn lockouts, upgraded to a toybox and splitcase.. Now my weak link seems to be axles.
Snapped like a twig with 38 sx's and 216:1 low..
Build em and I'll buy em.. Thank you, carry on..

Alright, you win. :flipoff2:

We got the ball rolling. FJ40 and FJ60 Rear axles in progress.

Expect product in 6-8 weeks (assuming a normal production schedule)

PS we got some slick shit comming on the 80 Rears

SICK! You guys rock! Now I just need to find an 80 rear!

PS we got some slick shit comming on the 80 Rears

Can you make them in 40 and 60 FF lengths too?

Dave

Yeah, they will be special order only though.

Would it be too much to ask for 6 dowel pins and a taper for 100 series studs?
:D

Does anyone have an idea of how fullfloater Cruiser axle strength compares to a D60? Is there even a comparison? I wouldnt mind getting a FF Cruiser axle WITH the chromo inners..

-Dustin

Why buy a full floater if Polyperformance is gonna be making Bling bling semifloater inners! It isn't gonna be worth the trouble to buy a new axle when we're getting upgraded stuff we can buy! ..
Gotta start saving my pennies now! AWESOME!

Thank you sir!

Well, gee. A week after I gave up on this idea and found an offset rear full floater Dana 60, you people get this going finally.

Now I guess I'll have to find a '40 to build up for my girlfriend to use these :D

Man, with the Orion and the upgrades available for the front, this is going to be sick, sick, sick!

Now the final thing will be a C Clip eliminator.....................

disk brakes..

Think something like this might be worthwhile?
Get rid of two problem areas at the same time! I hate pulling c-clips out if something goes wrong!

or
http://www.strangeengineering.net/catalog/060.html
Just ideas! Something similar to a minitruck would be fine with me!

disk brakes..

Keeps it from running out, yes, but the C clip groove sucks, would be nice to make it go away. Also, being able to remove the axles without draining the 3rd.....

NICE! Thanks for the update, let us know when there's pricing out!

For those FF guys, I spoke with the guys at Moser at lastweeks UROC comp (Portland, IN), they have been making the Landcruiser FF shafts... They sell them through some one out of Chicago (he told me to call him to get the info). Just a FYI

I want some. Cant wait.
:D

Chromo rears with longfield 30 splines up front will be perfect. I'm thinking I might try running some 39.5 irocs with that set up.
