Right now I'm stock (3.73, H4) and 30" tires in my 83. By doing the calcs, 33"s and 4:11's would be a great combo. My questions are: Has anyone found/installed junk yard ring/pinions? What Toyotas came with 4:11's? Are the axle codes the same across all Toyota trucks? I'm trying to go cheap with the JY stuff, but my truck has 250,000 + on the gears and they are just fine. I figure if I can find something in the low to mid 100,000's, then I should have no worries.

Gears in the 62 series are 4:11s. I have them with 33's and they are fine. I dont know about if you can swap them straight in but I assume you can since there isnt much difference between the two. I could be wrong though so hopefully somebody else will chime in.

....back in the saddle again....
gears in the fj40's are 4.10 or 4.11, and swap right into a 60.
FJ62s came with 4:11s, and are a direct bolt in. FJ40s prior to '81 (I think), came with 4:11s, but the pinion flanges are different. I think the difference between the flange and the shafts can be drilled out, but Im sure someone smarter than me will chime in.

I got two fronts gears (less mileage on them) out of 40's that I'm running in my 60. They are 4:11's and make the 33's run and feel like the stocker wheels. Speedo and rpms are pretty much right on and the same as the original gears and small stock tires. It's a really good match between the 33's and 4:11's. Don't really remember any problems using the 40 gears in my 60, all went in pretty easy.
Before I ran 35"s and now even 37"s (with 4.56s) I absolutely loved my 3.73s with 32"-33" tires, very economical, it was as if I had an overdrive on the highway - my RPMs were lower at 110 km/hr than having the old 31"s, fuel consumption was great and it still wheeled well, she didn't bog down too much on up-hills.

I've read a bunch of mixed reviews on 33's and 3.73's. The main reason I am looking into this is that I will occasionally be pulling a pop up trailer. I would like to move up tire size for the rubber overdrive, but don't want to lose trailer pulling power. Did you notice a loss in overall power, or would you recommend not pulling a trailer with 33's and 3.73's?Rig of Mortis said:

I have 33's w/3.73's. It works great on the freeway, pulls fine in the NW mountains to go skiing/camping - even loaded. Hill starts are a pain - first gear isn't low enough. I have to slip the clutch a lot on hills. I've pulled a light trailer with this setup. Had to slow down more on hills than w/out the trailer, but it worked. I think you can be happy as long as you have realistic expectations for how it's going to work. Now that I've used my 33/3.73 combo for two years, I think I'd be better off with 4.11's and going slower on the freeway.

Here is the scoop:
You can run 3rds from an FJ40. Up until 1979 they were 4.11 (9 tooth pinion, 37 tooth ring gear). Early to 1977 were coarse spline = weaker. So if you go this route, I reccomend 1978 diffs only. The bolt pattern of the 78 flange is the same as FJ60 through the 84 model year. Starting 1979 the 40s went to 3.70.
The FJ62 diffs are also fine spline 4.11. The flange pattern matches the FJ60 from 1985-1987. It's a direct bolt in. The output splines are all the same so if your bolt pattern is wrong, just swap the flange.
One other option is the gears out of an 80 series rear (note-rear only). I'm not sure the whole third will swap. The gears will, and they are 4.10 (10 tooth pinion, 41 tooth ring gear). There are quite a few sets of these around from people who have gone to lower gearing in their 80 series.
For 33's the 4.11s are an excellent ratio that feel "normal". For towing, I would be tempted to go even deeper, like 4.56 or 4.88. In my opinion a 60 series is a poor choice for a tow vehicle.

Can I just confirm that both Ryan S and lovetoski are running 3.73s.
Have you swapped your factory gears?
Please correct me if I'm wrong here, but wasn't the only 60 series that came with 3.73s from the factory a BJ60 (3.4 L diesel)?
I was under the impression that FJ60s and 62s both had 4.11s.
Bring me up to speed.

Ive still got my stock 4.11s and with my 34s i really need more gearing. Its absolutely fine around town or on flat roads, but any kind of hill and the speedo just starts dropping. Im gonna toss in some 4.88s whenever i get the money. With a 2f, stick, and 33s, i bet 4.11s would be great though. Oh, and all US 60s had 3.73s, and 62s had 4.11s.

Cruisers from E-12/78 have 4.11 (37/9) gears.
Cruisers from 01/79-8/87 have 3.70 (37/10) gears.
All FJ62 (1988-1990) have 4.11 gears (37/9)
All FJ80 (1991-1997) have 4.10 gears (41/10).
That's my story and I'm sticking with it.
Sorry, don't know about Canada spec trucks.

First of all, thanks to you everyone for all the detailed information. And I agree that a 60 is a poor choice for a tow vehicle, but I've got too much money into it and like it too much to get something else. First trip with the trailer was OK. Only OK because I kept it at 55mph. Other than that it pulled real nice. 12.5 mpg, too, which was a nice surprise. Using the calculator in the links, I come up with 2800 RPM with 33's and 4.11's going 66 mph, which would be sweet, and plenty fast pulling the pop up. Also I get a little lower low range with the 4.11's.
BTW, I'd get BFG AT's. I know that they don't measure a true 33" and can't find the thread the true measurements are in. Anyone know what it is?
I am in the process of swapping out the 3.73's for 4.88's. Put the 33 TSLs on the 60 and the thing was gutless. Went with the 4.88's b/c sooner than later gonna upgrade the 33's to 36's

As far as the whole fuel consumption thing that was mentioned--get over it--
you drive a Land Cruiser. Last I checked, I don't love the LC for it's mileage...I am quite sure that most of you don't either.
I ran the 33's on my 40 with 4.10's and it was an OK setup, but if you are going to go to the trouble of swapping the R&P, make sure you are getting the right ratio, (especially if you're going to tow with it) b/c it is not a walk in the park to change out. If you are just doing a whole new 3rd, then that is a different story.

You can get reasonable mileage from an FJ60 if you tune, tune, tune. Get all your smog gear straight, rebuild the carb (and maybe heads), new NGK plugs and wires. The 4.11 and 33" tires is close to stock, and there are people getting 15 -16 MPG in stock cruisers.
For better mileage, TAKE YOUR FOOT OFF THE GAS, and install an H55F 5 speed.

I popped out the stock 3.70s in my 60 for 4.56s with 33s. I hated technical sections of trails and STEEP decents with the higher gears. The 4.56s are a little low on the highway but great on the trail.
Think hard about what you want to do with the truck, if there is a possiblity that you are going to a bigger tire you might consider 4.56s.
From all the literature I have seen US 60s are 3.70 not 3.73, just like FJ40Jim shows.

In my FJ62 I run BFG 33x10.5x15 AT's and have 4.56 gears.
According to my GPS, my odometer reads 4% less off of actual mileage.
This is the average over 10,000 kms.
Of course, my truck has the automatic.
I like the way it drives except for how long it takes to get up to speed.
I get about 16 mpg on the hiway.
