Some one pinch me! 4.56 gears???

Scramble

Does my truck really have 4.56 gears? (3RZ - 5 Speed) I always assumed 4.10 because mine didn't come with a locker. This is a pic of my door tag & SS gear ratios.
The tag says 225/75/15 for weight but my T4R came with 265/70/16 from the dealer?
This would save me a lot of money in re-gearing.

Lift the rear tires, spin the wheels and count 20 rotations of the drive shaft and divide by 2. Only definite way to know otherwise I wouldn't trust the code.
 
I have only seen the A05A code once in a 4runner in a junkyard. Pulled the pumpkin to count the teeth and it was indeed a 4.56 gear ratio.

Pull it to verify but if I were to go on a hunch, then yea, that is what you have.

Let us know.

This makes me feel like it's Christmas morning! Not bad for a Base model!

I'm at work (nights), I will check as soon as I get up tomorrow! I have a new Hi-Lift I need to try-out anyway.
 
4cyl 4x4 manuals were the only ones that came with that ratio. I bought my 4.56 front diff from a 4 cyl 4x4 5spd. I had already upgraded to 4.56 in the rear so it was the perfect OEM option (my truck was a 2WD at first, had to convert to 5spd and 4x4. The 2wd auto 4 cyl had 3.91)
 
3rd Gen Toyota 4Runner Axle codes:

A01A - 3.73
A02A - 3.91
A03A - 4.10
A04A - 4.30
A05A - 4.56

This applies ONLY to 96-02 4Runners

So yes, you have a 4.56 gear set. Ultra rare :)
 
Btw if you ever wondered:

1A5=Desert Dune Metallic
FQ45=Tan Fabric, base model/standard interior (NOT the upmodel SR5)
A05A=4.56 Gears
W59=5speed Transmission

Also, all Base, SR5, and SR5 sport came with 15" wheels listed on the sticker. The 16" wheel/265 tire setup was considered a factory option, thusly not listed on the sticker. All Limited's say 265/70/16 on the sticker, because the 16" wheel/tire combo was considered Standard equipment instead of an Option.

I hate to be the one to say this but you have 4.56 gears because Toyota knew that 2.7L equipped 4Runners will need them even for a stock tire size.

I don't know what you mean? You aren't raining on my parade.

3RZ's came with 3.72, 3.9, 4.10 & 4.56's. I assumed I had 4.10's. I ran 275/70R16's for 10 years on my stock 99 talls & had no problem doing 80mph on the hwy.
I'm moving up to 285's (D rated) in a few weeks after I put my lift in & didn't think it would be a problem because other people here are running them on their 3RZ's. But then there's been a lot of gear ratio talk on here lately that was making me worried. If I have 4.56's I should be fine. If I have something lower I will re-gear to 4.88. with lockers. :-)

Edit: 600th Post!

Now I feel I should have taken the time to pull those diffs. Oh well. Thanks to DC for the clarification.

And to the OP, enjoy!

Thanks Josh, You lean something new every day!

Apparently I have 4.10's. Good to know! Thank you for that tidbit of information.

I love what you did with your truck. I spent one night reading your build thread. Probably 5 hrs until 5am! LOL
 
Yep if you have 265/70r16 tires you have 4.56 gears. Many 4cyl 5spd cam with them. Now if you have an e locker then wow. My TRD Sport Tacoma was 4cyl 5spd 4x4 and had 4.56 gears, it had a lot more get up and go then my V6 auto 4.10 4runner.
 
Love the MKIII supra as the avatar bwt. I miss my 87 turbo so much and want another MKIII Supra so bad as a toy.
