I don't think the AP2 needs a reinforced diff. (Besides, Comptech was the only one making one and they are done now.)

 

does anyone remember how much tax is on the room? i'm trying to put a chart together for everyone but i forget what they charged down there

 

Nope, sorry.

 

np... just want to make sure my fellow s know what this is going to cost them..

 

I don't know, I assure you it is on accident.

Here is a pic I found:

4.77 on left, 4.56 on the right.



4.56:


4.77


The 4.56 looks significantly stronger (and was engineered to be so.)

That said, the majority of failures (as I understand it) is from the pinion gear being "pushed" out the back. This is why people go with the reinforced diff. The AP2 does have a stronger diff cap than stock. Unless you are going FI and going Drag Racing every weekend, the AP2 diff is perfect for you.

 

All this gear talk makes my head hurt. My brain just doesn't work that way, despite being raised by a mechanic.

 

I just wanna get gears.

 

i just heard the same thing (and the same comment you made about not being able to find one anyway)..

thanks

 

The gears let you trade top end speed, for low end torque.

The bigger the number of the gears, the bigger the change.

The stock gears are 4.10.

So 4.44 lowers the top end a little and gives a little more low-end torque.

4.56 a little more.

4.77 more than that.

The one negative aspect is that you will cruise on the highway at a higher RPM than you did before in the same gear at the same speed.

Does that help?
