3.73's

[rwboring]

CJpony has a daily deal for 3.73's part number: M-4209-88373 do these fit the 2013 or just up to the 2012? If they fit they are at the lowest price I've seen.

Also, I've heard if you buy Ford Racing parts and have them installed by Ford it doesn't void your warranty, is this true with gears?

Before anyone states to search I am at work and just happened to see this but can't research it

Any input?

They should work, 8.8 rear has been the same for years

As for warranty if installed by dealer, ask your dealer. It will be up to them, thats not a gurantee

You will also need to buy an install kit and new pinion bearing because the pinion bearing that comes with the install kit does not work on the 2013 GT500. The 13GT500 uses a larger F150 pinion bearing. Lethal performance has them but I'm sure you can get these from Tousley as well. Oh, don't forget dif oil!
