ADDED NOTE: The 2011 E-Series FSM specifies C4 - 3.73 ratio. limited slip, single rear wheels
Just an FYI (and I know it is old but just adding to the knowledge base)
I just bought a mildly abused 2011 E-350 5.4L 4R75E (Trans code Q but the cross brace is marked 4R70W) Super Duty with the C4 axle designation.
The build code is:
3.73 2014981-3 L-S
The -3 does not show up here:

2014981-1 Dana 60HD '11 (Ford) Rear 3.73 4.10- 35 Sp. C-Clip More..
2014981-2 Dana 60HD '11 (Ford) Rear 4.10 4.10- 35 Sp. C-Clip More..
I'm assuming the -3 or the L-S stands for limited slip as implied by the C4 axle.
