Re-gearing diff advice

I swear my 14 TE has 4.11's in it. It's way to peppy with F&R bumpers, winch, roof rack and bigger tires to be 3.73's.
I swear Toyota has never had a 4.11 gear set for the 8.2 rear diff. The only gears Toyota put in the 5th gen 4runner are 3.73s and 4.56s in the dozen or so 4 cylinder 5th gens they made. You can get 3.91 gears from the 2010+ 6 speed manual FJC.
 
I wanted to triple check my ratio today, so I called 3 different dealership's parts departments. All 3 told me with my VIN my ratio is 4.11. Do you guys think a 4.11 to a 4.56 will be noticeable for me?

Do you have a 5th gen 4runner? If so, you don't have 4.11 gears
 
I do have a 5th gen. It's a 2014 SR5.

However, I find it hard to believe that 3 different people looking at the parts sheet Toyota produces would give me the wrong diff ratio. It seems highly unlikely.

From The horses mouth, 2014 4runner product information sheet from TOYOTA

2014 Toyota 4Runner Product Information | Toyota

Only differential listed is 3.727 (normally stated as 3.73)

The 2014 4runner NEVER came from Toyota with a 4.11 gears, and to my knowledge no 5th gen 4runner ever did either

No idea what product sheet your Toyota dealers are looking at but ask them to take a screen shot of it and send it to you if you don't believe us.

If by some magical means you do indeed have 4.11 gears I will relent until then :gun4:
 
Yeah, I agree. That's what my product sheet says as well. Just very frustrating to get inaccurate information from a "trusted" source. Aka the dealerships.

So, what the hell is going on here? All these dealers are reading the VIN wrong? I have always thought they were 3.73..... I'm just saying it's really weird. I'll call another dealer on Monday and see what they say. At the very least, it would show some kind of glitch in the VIN system.
 
Ok for those that have 4.56 gears... what RPM are you at when running 75mph and what tire size are you running.

Currently; I'm dealing with lack of grunt in my 4runner by leaving it on 4th on the streets and only shifting to 5th once I pass 65mph. And by doing this I went from 13mpg to 14 to 15mpg. Just by forcing the transmission not to down shift all the time.

2400 at 75 with 305/70/17s (34.2") with the TC locked.
This is a very helpful tool: Gear Ratio Calculator
 
Also - FWIW it has been a looooong time since Toyota sold a 4.11 diff. Probably around 30 years ago or more. IIRC it was about 1980 or earlier.

4.11 gears are weaker than 4.10. 4.10 has a 10 tooth pinion while 4.11 uses a 9 tooth pinion. There's not a good reason I can think of why anyone would ever build a 4.11 gear set. I know they exist - even in the aftermarket - I don't know why.

Just wanting to set that straight. If a dealer ever tells you you have 4.11 gears and you're not calling in a 1978 fj40 - the dealer is probably wrong.
