2.28 or 4.7 Toybox?

You will have to modify the rear crossmember too so you should factor that into it. I guess since it is flat in Florida you can get by with 37" and 4.11. The whole point of gear reduction is to go slow. Anyone would spend $475 for 2.42 more in gear reductions. Which is what you are getting with the 4.7 toybox. I can run the numbers later but another option is to put in a 5 speed with the lower first gear and change the gears to 4.88. This will give you 2.05 more in gear reduction and you will have a 5th gear for on the highway. I would go with the 4.7 and be done with it. I had to make the exact decision and ended up with the 4.7 and am very happy so far.

The h55f with 4.88s would give you the same RPMs at highway speed as the h42 with 4.11s but the crawl ratio would only be 54:1. (with no toybox). If you want to use the toybox with the h55, then you have to use the 4.7 gears. I guess you could use an NV4500, but that produces another set of problems.
 
I ran a 2.28 in my toybox when I had a stick... It was very nice but honestly after wheelin with it for a while I wished I had gone for the 4.7 which is what I did (4.0 gear actually) after my auto conversion. I mostly wheel with the case in 4h and the toy box engaged. I fine it about perfect.


I'd go with the 4.7 and be done with it.

What auto and what toy box are you running!
I WANT THIS what ever it is!
I didnt think you could do a box with auto trannies?
Please, school me on the process, and if there is a thread on it, I wanna know it!

Thanks!

Kieth-Why don't you do a manual transmission conversion, and that will open up your options regarding a Toybox.

I have all the parts, I'm just waiting for the right FJ62 to come along:D

I do have a spare H42 you can have if you want to go this route.
 
I'm running a TH350 auto and the Marlin toybox with a AA adaptor between them. :) It makes everything so much easier. :)

So much easier than doing the manual conversion?
Im still thinking hard about doing a V8 swap in my rig, which means that the A440F will be going away with it, but I was unaware that you could get a toy box for an auto.
Ill have to consider this as an option.
HOw was the install? What was the wiring like?

I should probably send you a PM insted of hijacking this thread!

Sorry about that!

THanks,

Andy,
Im just considering my options for this...Since Rubicon, Ive been thinking A LOT on this mod.
What I got from George's build thread, and talking to Brett, it sounded as if it was BIG MONEY and a LOT OF WORK!

And this surprises you how?
 
Marlin is working on a A440+toybox plate


from the diesel section

We are currently working on an A440 crawler (MC26 adapter kit). The MC26 would allow the use of any T-case behind a RF1A reduction housing ( 3spd/4spd, split case, RF1A, VF1A and even Dana junk). We just have so many projects in the works that they never get finished. We have started changing this.

BTW off topic does any body know the proper Toyota name for the 3spd, 4spd and Split case? (example: RF1A is the mini truck gear drive case)

Thanks
 
Before you decide you should try to get some seat time in a Toyboxed rig with the setup you are thinking about running.
That is great advice. Last year at Tellico I did get some rides. Man do I wish I would of asked more questions on ratios they were running.

I don't think I want to go up there without any crawl and be miserable on the trails. It does make more sense to go with the 4.7 and be done. Unfortunately for me the $475 makes the difference of buying it now and getting it done or waiting too long and maybe not getting it done. 4.7 gears are $399 and a days labor if I decide to go with them at a later date.
If I was going to go with the 4.7, I think I would buy the 2.28 Toybox for $1525 and a set of 4.7 gears for $399, change the gears out before install and have an extra spare set of 2.28 gears to carry around. All at a price just under what the 4.7 toybox alone costs.
 
OR you could just do the Marks gearset...correct?
Seems like a better price-benefit, and still insanely low gearing. Less things to go wrong as well is seems.
 
With the Marks gears you loose the ability for the mid low range. You have 4 high and 4 very very low. Toybox gives you 4 high, then 4 low, then toybox only low, finally toybox and 4 low.
 
On a similar topic has anyone seen a write up on the installation of a toybox in a 60. I have found one on a 40 but there are differences. I could have sworn that at one time I was able to find one somewhere on the web but I looked for hours last night and had no luck.
 
You dont need to wait for marlin to make a toybox to A440f adapter, you can already use the mudrak 4 speed to 203 adapter setup with the auto. You just have to cut down the output shaft. I suggested the idea to cam at IPOR and since he actually has money unlike me he made it work.

The only problem for those that unlike cam have a full body is that you will probably have to give up your rear heater and the floor under it because that is where the 203 will sit.
 
I like this thread .. and leave my comment about CRatio ..

I thought it depend in tire size, engine, tranny and what kind of off road you do .. I really take those issues in mind coz I was in the middle of t-case gear set or toy box ..

My t-case come factory with 1.96:1 with 4.56 R&P and the 2.28 toy box I would be on 100:1 range .. but I really need it . ?

My answer was most of the time no .. sure there are some situations that you like to need .. :D but most of the time in my kind of off road here ( mud ) you need speed and displacement ..

For other the low end torque of my diesel engine help me ..

just my .00002 cents ..

With Marks you are replacing 2.28 with 3.05. For $100 more (not including modifying the crossmember), you can get a 2.28 toybox where 2.28 * 2.28 = 5.2. With 4.11 diffs, h42 that's 76:1 which is all your would probably "need". With Marks you only get 45:1. 40:1 is considered entrance-level crawling gears. 80:1 is supposed to be ideal for Rubicon.
 
80:1 is supposed to be ideal for Rubicon.


In a 40! Having followed Pismo Jim through the Rubicon more than once, I'd say double that figure is just right!

In a wagon, the lower, the better. If Rubicon is the goal, then the 4.7 gearing in the Toybox is a no brainer.

I totally agree with your conclusions regarding the Mark's gears----not worth it.
 
Toybox ordered:bounce: 4 to six week wait :frown:

On a similar topic has anyone seen a write up on the installation of a toybox in a 60.
There was a thread on a 60 Toybox install a couple of months ago. I think it was a silver 60. I searched and couldn't find it. I did save some pics and a few paragraphs from the thread. Rekut, PM me and I can send you what I saved.
I would still like to see more though.

I guess the Toybox has a place to bolt mounts. I'll probably mount my crossmember to the tranny though.
 
See my post above. Considering the gearing change - 1.99 or 2.28 to a 3.05 considering the $1400 price tag- it's a horrible deal.

Stock - 3.555*2.276*4.11=33.255
Marks - 3.555*3.05*4.11=44.56
Toybox - 3.555*2.276*2.276*4.11=75.69 And that's just for the 2.28 box

Sorry, meant to quote this post in my response.
