38's on Toy axles? - Pirate4x4.Com : 4x4 and Off-Road Forum

Flatty · 08-22-2001, 11:37 AM

I know people have done this. I was wondering if when you do this you spend a whole lot of time outside your rig changing birfields, or are they strong enough to handle to big tires. I will be wheeling it, but not as hard as I used to wheel my Flatty. Also what kind of lift should I do to clear these. I know some MASSIVE fender chopping will be in order. I was thinking about getting some AOR orbit eye springs for the front and back with a body lift. Will this work?

I haven't broken a birf yet, 38/12.5 SX's on stock toy axles in an 85 Runner. I've been through most of the hard AZ trails. I'm going to break one some day, but I've got two full sets of them with me. JackA has broken one on each side with the same set up. I started out 190:1 and am not a throttle jockey. Steering stops are all the way out too. It all depends on your driving style and what you wheel if you'll break them. It only takes an hour to change one working casually, so I'm going to stay Toyota axled for a while and see where it gets me.

Haven't broken a birf yet either. 38.5×15.50's on 10" rims. Add to that nearly 300hp/400ft-lbs of torque and a welded front diff. Have run many of Colorado's hard trails as well the Con. I am counting the days until I do break one though <IMG SRC="smilies/biggrin.gif" border="0">

i did,t break any more than when i had 35's. average of on a trip, sometimes two.

just do it. you can always slap a 44 in there later

vova · 08-22-2001, 04:34 PM

Just run it.

...How much does this cut down on your ability to turn?

not too bad really...

Think of it this way: an extre few seconds to make a few more points on that turn, or changing a birfield? <IMG SRC="smilies/wink.gif" border="0">

Ask Sam how well this truck can get it awn!

He's still running stock birfields with 38's and so far so good!

Just run it. I have only broken 2 in like 20 tough runs. The clearance under the pumpkins is great. <IMG SRC="smilies/glasses.gif" border="0">

Sam · 08-22-2001, 09:53 PM

Dima, as Audra said, that Toy of Johns was so pimpin. He walked course #3 at the MCR like it was nothing. In fact, most obstacles I saw that thing on, he walked. I run the 35s on mine and have broken. He ran the 38s pretty hard that weekend with Birfs and didn't break. So I can only assume as long as you don't get stupid on a Birf, you can make it work.

What are you puttin these 38's on? Pics <IMG SRC="smilies/biggrin.gif" border="0">

TROYOTA · 08-23-2001, 07:35 AM

I broke a few birfs when I was running 33 tsl's. I just put some 38 x 14.5 sx's on the same 10" wheels. When I get all the clearancing done to the body, I will be ready to test it out. I am not really concerned about the Birf's. I know how I drive, and I think that is really the biggest key. I am not saying I won't break anything, but compared to some other people I know, I have a better chance at making toy running gear last longer.

camo · 08-23-2001, 07:44 AM

ok before we all get to birfs are great happy around here. remeber it is gonna depend alot on how much your rig weighs and how hard you are pushing it.

i still say do it. just be realistic about what you got. i have broken 4 dana 60 axles with my 38.

sams got the right idea......as light as possible

Hi folksGot to have my 2 bits <IMG SRC="smilies/cool.gif" border="0">

I have had the same birf's in my truck for 4 years, used at that, and never broken one using 35's and 36's now that said I will mention one or two things already said when using a birf you must be aware of it's limits
such as power while wheels are fully turned and snapping into reverse both wonderful ways to spend the next hour and a half changing a birf. Take your time on the turns and let your birf bearings ramp backwards lightly before you hammer on reverse and they will likely last awhile, but you got to admit that’s a lot of stuff to think about when your in a uncomfortable spot.

I don’t think that 35 36 or 38 will make a whole lot of difference with breakage its just how you want to wheel. Wheel hard <IMG SRC="smilies/rainbow.gif" border="0"> break it, Wheel light keep it.
Now would I put a birf diff in my next truck...Not a chance baby!

Like everyone has said, it is how you drive. I am very hard on my vehicle and with the 38's I have broken birfields, redline shafts, and I am now running a narrowed dana 44 with really good luck.

chris_danoff · 08-24-2001, 04:56 PM

Having more problems with stock rear drivelines than birfs. Birfs - 1 Shafts - 2
