What size diff do i have

Hi guys,
been reading a lot of stuff lately looking to find what size differential i have.
this is a real pain in the butt, but can any body help?

Possible buying a locked 3rd member from another member with the same truck later on when he goes back to stock but wont be for a while, but if that sale falls through illbuying an assembled 3rd member with an arb locker from ECGS and need to know what size to get

2013 tacoma DCLB prerunner, does not have an Elocker, 2 wheel drive

can anybody help?

 

8.4"

 

How could I tell this?

 

Remove it and check? All 05+ tacomas that don't have the 8" e-locker have the 8.4" rear differential with the bearing cap truss

 

That's what I thought too, but I'm not a percent sure

 

anybody else know?

 

He knows his shit.

 

I can not find the axle code, it's really annoying me

 

Ok I'll trust him haha

 

Is the 8.4" a stronger rear end?

I have a 2007 SR5 4x4 V6

 

Mine does not look like that

 

Just look for the A/TM code:

Hey found my code, A04C says I have an 8.0" rear end, don't have a locker tho and I thought that the lockers were only 8" and non locker were 8.4"

 

The 8.4" is still and 8" ring gear it is commonly called the 8.4" due to the thicker gear and the large bearing cap truss on the back

 

Thank you for the clarification I don't feel like I have been promoted from wearing a helmet and eating glue to just eating glue
