39.5s too big for toy axles?

[joeshmo]

well i have a set of 39.5 irocks to go on my rig,  dual cases with toy axles and a 22re.  should i expect alot of carnage, i dont like to do things more than twice so should i just save my pennies to fullsize? and i will only be locking the rear, mabey

[Thomas P]

if you run them you NEED 30 spline longs or you WILL bust birfs, i have been runnin 42's and 39.5's on toy axles for about 3 years with no probs, but i have the longs........

go with the longs as soon as i get the money i am, i have broken both my birfs in the past month. not fun and im just running 37's

[Birfailed]

37's are huge on stock birfs

[THK Matt]

im not as hard as you guys are on your axles down there. I only have snow, mud, and fire roads in my area... not to thread Jack, but 37s will kill my birfs too huh?

or not as fast as they do down there on trails you all ride.

[Ramrod]

if your not locking the front you will be fine stock no problem, if your worried about it bring a spare birf you might break one once in a while if you like to get crazy

seen em snap like twigs on 36's without a selectable locker

[THK Matt]

Ill be open in front.
aussie rear.

I should be fine then.
only thing that will lock is the hubs.

[808]

yeah i just broke mine in the snow not really doing anything. but i am also locked in the front

[THK Matt]

yeah I should be fine then.

[84socal]

the majority of the time why the stocks explode are cause there stuffed at a full turn  and theyr weakest at that point   iv run stocks full locked  on 35s and 36s     and havent broke   but maybe im just lucky  with my 3500rpm clutch dumps

but got longs now

[86bobbedtoy]

I will be running some 39.5 in a week or so
I just snow wheel,
but I hope I never break one.

[toyotanner]

i ran 37's on mine open in the front never broke a birf in a year of wheeling it that way

[THK Matt]

awesome, i have high hopes then

[joeshmo]

i just dont want to spend all the money on longs ect, only to have to go fullsize

[Birfailed]

Geez, maybe i'm a crappy driver, I had to step up to a chromo 35 spline 60 to keep from blowing up.

maybe   the majority of the guys i go to the hammers with  have tot axles and longs   and run 38s-42s   and theres one guys that seems to be able to break them   but he is a throttle jockey on 42s

[suprawheeler]

i have 41" Iroks and havent broke a long field yet

[whokrz]

I run 37" MTRs and I haven't broken a birf yet, but I drive really easy on them with not much gas. It is only a matter of time though until it breaks. My worry with longs is that the differential is looking like the weak point and that is a lot of money to replace. I carry a spare birf and save for 60s which will also give me a full floater in the rear.

[lilbuddy]

Yeah thats pretty big on stockers.

I wouldnt even run 39.5s on my chromoly'd dana44....

Just my
