4.56 rear differential

96-04 Tacoma or 96-02 4runner 8.4" rear open differential. Has the girdle on the bearing caps.

Good working order, no issues. Worked great on my 4x4 with 35" tires.

Only selling because I picked up a locker.

Located in Phoenix Az.

This will also fit 05-15 Tacoma without elocker, as well as T100

 

But not any 4Runner as 09 and down either had 8" elocker or 8" TV6 non elocker.

 

Also fits 1st gen Tundra w/o mods. The pinion flange will have to be redrilled to work with a 2nd gen. And yes will not work with 4runners.

Cant beleive Erik still has his site up. Hope it is mirrored somewhere.

 

If you have larger tires, or plans for them, its time to regear!

 

I’d love a regear, but I don’t think I’ve seen the matching front to go with it.

 

They seem to be elusive. I got the front and rear (this one) from a yard on ebay. He said he had more fronts available. I can ask tomorrow. @BartMaster1234

 

I’d probably do 4.88 if I had to regear as I already have 4.30 - this would be a great upgrade for anyone with 4.10 though.

 

For 33's?

 

I have 32's, but I have the four cyl supercharger too so the regear would help a lot.

 

The 4.56 gears with the 2.4 made a huge difference. I highly recommend getting them.

 

anyone have the 4.56 gear with 33’s? I don’t want my rpms to be too high on the highway

 

I had this 4.56 on the truck for 1 day with 33s before going to 35s. I have the V6 with automatic transmission, and felt the rpms were a little high on the freeway. I dont remember the exact rpm, maybe 2750, for sure less than 3000. The truck did move very quickly and easily from a stop/low speeds. If you do alot of rock crawling type driving, this would be a good ratio.

You might want to look up auto vs manual overdrive gear ratios, maybe it will be ok with a 5 speed V6 and 33s. Otherwise consider larger tires. 4 cylinder is another story.

Also, I was told 4.56 was not a good choice for 35s and to only consider 4.88 or 5.29. After using the 4.56, I have to disagree. It's nearly perfect, very close to 4.10 and 31s over all, maybe a 31.25~. I'm sure some will disagree.

This is a good approximate representation.
31s with 4.11 ratio = 2896
35s with 4.56 ratio = 2845
Difference = -51 rpm
31s with 4.11 ratio = 2896
35s with 4.88 ratio = 3045
Difference = +149 rpm

Basically, you can see the 4.56 with 35s is closer to a stock ratio than 4.88 with 35s. Both will obviously work.

 

Another example.


2004 Tacoma V6 Auto 4.10 31s


1996 Tacoma V6 Auto 4.56 35s

 

yea I’m on the highway a lot going at least 70 but most the time 75 or 80. I think my rpms are at around 2300 with 265/75/16 my stock gears are 3.73 but want to move up to 285s soon

 

Shooting from the hip, you probably want 4.10 or 4.30 gear ratio, assuming 3.4 V6 auto. @_anthony_
