Default R8 Axle Code?

What exactly is the R8 axle code? It's on my door, but I noticed it's not listed in the sticky. It seems that some sites suggests it's still a 4.10LS while others say 4.56LS.

Did they have 4.56 axles in stock Rangers at one point? Is there a definitive way to tell other than what's listed on the door?

I can tell you that unless somebody has changed it, it won't be a 4.56. Also, I thought the 4.10ls code was R7 but I'm not sure.

You can look and see if a the tag is still there with the info

will be like 4 10 8 8 which mean 4.10 8.8

The 4.56 from my understanding is a mythical axle.

If someone changed them you would have to pull the axle apart and count the teeth on the gears. Or you can lift the back up and spin one tire and count the revolutions of the other.

Rangers never had a 4.56 factory option. Your axle is a 4.10.

In 2008~2009, Ford added the R8 Ranger code for the 4.10/31-spline/3600lb axle w/Torsen geared LS that was an option in those 2 years on the FX4 Off-Road. The 4.10/28-spline/2750lb 8.8" axle w/Traction-Lok clutched LS used code R7.

For 2002~2007, The R7 code applied to any 4.10 limited slip 8.8 regardless of whether it was a 31-spline/Torsen or 28-spline/Traction-Lok.
