I've swapped gears in most every Mustang I've owned, and the 8.8" rear end is super tough, so don't worry about warranty. Get the gears (4.10's FTW) - you'll thank us later!

I ran 3.73's in my '89 LX 5.0L and the 3.73's in my '11 5.0L get way better mileage than the '89 ever got on the highway. Don't fear the gear! 4.10's are awesome in the S197's.
