Nope. Ford changed the pinion design for '11 and up 9.75.

What break in procedure do I need to follow when installing the gears? I should installing then on Tuesday, I ended up buying 3.73 gears and they are Genuine Ford OEM gears.

Are you having them installed at a dealership? If so, how much are they charging you? I got a quote from a local dealer for a gear swap and it just seems way too damn expensive.

Not at the dealership, at a performance and restoration shop. They do gears on all sorts of drag racing cars all the time. I was quoted $275-300 at most. How much did the dealership want?

Gears plus install was $1600. It was with 4.10s, but still more than it should have been.

The gears alone will be near double that quoted number if you have a 9.75 rear. Ford is the ONLY manufacturer for gears for the 2011+ 9.75 rear. The other bummer other than the outrageous price, 4.11 is the lowest gear made..... Hope the aftermarket steps up soon.

i hope so too

For 4.10s, yes that is true. For 3.73s, you can get them from tasca for $205. I just need to find somewhere to install that doesn't want almost a grand.

Here is what I got, I can't wait to see how big of a difference going from 3.31 to 3.73 gears and a JLP tune

Nothing like changing gears. I have always done my own using paint and checking the wear pattern. I put 4.56 in my 98 4 wd and it was a job! You should see a big diff going two sizes .
