I have a 2001 SCAB 4.6 2WD running 285/75R16 (32.8") with 8.8 / 3.08 open diff, yeah a real turd!
But I finally found a shop over here that can redo my rear end, since this is much too involved for a weekend mechanic like myself.

For the gears I finally decided to go with 4.10 because it's my dailydriver and the commute is mainly highway.

But what brand should I choose for ring & ring & pinion?
Motive
Yukon
Ford Racing

For the diff I decided to go with a Eaton Truetrac 913A561 or should I pick different brand/type?

Thanks guys!

 

Any of those brands would be fine, and a Truetrac is a good choice.

Make sure you get a programmer to correct the speedo/odo and get some good custom tunes with it.

 

My 2000 F150 5.4 with the stock Traction Lock rear was still working fine at 170k miles when my buddy sold it and I lost track of it. My current 2002 with a 5.4 and stock TL is still working fine at 142k miles. The Ford TL is much cheaper and it has done a fine job for me.

 

Got a programmer from powerhungry back in the days, so speedo/diff setting will be easy. Why would I need a custom tune?


Traction lock like a posi traction? The price on the Eaton over at summit is really nice...

 

Custom tunes are always better than canned tunes.
