Last Sunday, I took this pic of Cruiserdrew's 40 and a friend's FJ.

The FJ is really nice. I think it does real well offroad. But it's no FJ40.

Here's another pic of my friend's just finished 72 Resto and my FJC. We went wheelin' after that and He was impressed of what the FJC did with regular Street Tires. But there's no doubt in my mind that the ultra low gears on the 40 and the extra articulation(not much though) has it's advantages.

Your new FJ must be the automatic. The 6 speed FJ has lower 1st gear crawl ratio than the older 40. If I remember right, it's 4.69:1 for the new FJ and about 3.69:1 for the older FJ.

I'll have to go look now, because I am not totally sure on those numbers but that sounds correct and I know the newer FJ definitely was a lower geared 1st gear ratio.

 

[Cruiserdrew]

The FJ40 pictured has a 7:1 first gear. See my sig line.

It was fun hooking up with the FJC owner and his wife. He was at the start of the Rubicon "looking for a trail". To prevent death and carnage we took him over to Gerle Creek for some fun with little risk to his new FJC. He came through with such a big smile, I'll bet his lift and new tires are already on order.

Andy, noticed you put the hardtop on the 40. Looks good.
I wonder if they will offer the FJC in that green/white combo- would look pretty cool I think.

Cool did you change out the gearing, order an australian ported tranny, or put in a SM420..... all those options could get that kind of number. Well, I think maybe the australian tranny is a little higher. SM420 is my first guess?

The only tranny with a 7-1 1st is an SM420................
The Toyota trannys come nowhere close.

I am not sure if he regear'd it or not but It def had a higher crawl ratio. He was barely moving that the F155 was almost at "red-line" he had a tach. I know he's locked both front and rear so I assume he also went ahead and regear'd it.

What's the final ratio for the 40? and I have an MT6 not an automatic

edit: I read on the 40s section that the 72-73 came with 4.11 gear ratios instead of the 3.73 of the FJC

I might add that an FJ40 is nice too and does ok on road, but it is definitely no FJ Cruiser (also a 4.0 liter)! I can tell you which one I would rather drive! No offense to the antique FJ40 crowd!

Honestly, FJ40's are terrible on the road. It would be a terrible commuter. They are noisy, hot, unsafe. Offroad though, they are perfect, with the right balance of power, torque, strength and ability. No question, even from this antique owner, the FJC is a better road car, but I don't think even a lifted FJC would want to follow me through the Rubicon, antique or not.

BTW--not that it matters, but the FJ40 has a 4.2 liter, with less power, less torque, more noise, and worse fuel economy. But....it's still on the road in original form after 30 years, and can lug down and grunt at 400 RPM without stalling.

how many cylinder do the F series engine have? I know they're very low rpm engines. I guess due to the massive sized pistons.

I thought you have a 40 ?
Just count the plugs and you will have your answer.
The F is only a tad smaller in displacement.

Actually the 6 speed FJ Cruiser comes with 3.91 gears, and the Auto is 3.73.......

Yeah the older than 79' FJ40 came with 4.11 gears.

The final crawl ratio for the FJ Cruiser taking into effect all gearing was shown to be 41.84:1 for the 6 speed, and 33.76:1 for the automatic.

The Toyota trannys come nowhere close.

Like I said, the SM420 was my first guess. Usually the drop in american made transmissions are SM420 or SM465 but the 420 seems more popular.

For myself, I like to keep my Cruiser all Toyota, so I'd opt for the australian tranny which is still pretty low.

The 40 is locked up in a wharehouse in florida from when i lived there... and I never really bothered with it till I bought the FJC and like ppl have told me the LC bug bit me. It's some sort of hands me down.

before I bought the FJC I am/was more of a racing kinda guy. If you read my signature. Under the 40 there's that mustang GT killing machine
edit: so I guess the 79- 40s have a crawl ration similar to the Rubi?

This question is a tad hard on your Cruiser cred! All the F series engines have 6 cylinders, inline format. They are built to make torque at low RPM but not because of large pistons but because of a long stroke and a number of other factors. Just think tractor motor and you'll be close. It isn't sophisticated, but it's not fussy either. The F, 2F, and 3F(E) motors are all basically similar and had a production run of nearly 30 years.

The 7:1 ratio is due to an SM420-it's in my sig line! The lowest ratio cruiser tranny I know of is roughly 5:1 in first. Most in the USA came with 3.5:1. All but the 5 speed have a 1:1 final, just like the SM420 and SM465.

so I guess the 79- 40s have a crawl ration similar to the Rubi?

Not really. The Rubicon comes with a 4:1 transfer case. I think the stock t-case gears on the late model 40s (79-83) are 2.2:1.

Should mention: I own a 1981 FJ40. I have swapped out the gears in the t-case for some of those Mark's Gears from Australia. Now I'm at 3:1.

Still shopping for an FJ Cruiser...

 

[TexasBadlands]

All that gear comparison is irrelevant. If stock gearing isn't enough for you in a Toyota, just drop in a Marlin Crawler. The stock gearing is more than low enough for almost 99+ % of anything you can get yourself into in either the older FJ or the new one. Anything else is just "well my gearing is lower than yours, so there!" kind of stuff.

The stock gearing in a 40 is crap. It took me all of 50 feet into Full Size at my first BHCC to realize that. That's why I swapped in an SM420 with a 3-speed case.
Marlin doesn't make low range sets for non-split cases anymore.

50 feet into Full Size what at your first BHCC? What does all that stand for?
